Seismic refraction measurements were used to draw a new bedrock contour map in Morris County, New Jersey, where the major ground‐water supplies are found in Quaternary sand and gravel deposits filling pre‐Pleistocene channels. Aquifer performance tests aided in tracing the continuity of the Quaternary aquifers in these channels. In one case, the lack of continuity between two wells substantiated the seismic prediction that two separate channels were involved. The success of the seismic exploration emphasizes the value of using such methods, so that test drilling can be devoted to exploring the more favorable areas for production wells.

The cyclostomes have been shown to have only feeble immunologic responsiveness. One of their number, the hagfish, appeared to be totally lacking in the ability to actively acquire antibodies.
Among the elasmobranchs, the sharks have received the most study immunologically. This group demonstrated a variable response to antigenic stimulation
Of the teleosts, the salmonids and the cyprinids have been the more frequent recipients of experimentally introduced antigens. These fishes, as well as other species of teleosts, are quite active and quite consistent in their response to various antigens.

Two of the samples are from the basal ash fall that preceded the ash flow eruptions; one of these two samples was collected within 1 m of the contact of the Bishop Tuff with the underlying Sherwin Till. The third sample is from near the present exposed surface of the Bishop Tuff. The minimum age of the Sherwin Till (Kansan?) is thus 0.7 million years. The samples used for previously published age determinations of about 1 million years were probably contaminated with older material. Paleomagnetic results from five widely separated localities indicate that the welded part of the Bishop Tuff became magnetized when the geomagnetic field was normal and that it may have cooled in several centuries or less. The Brunhes-Matuyama polarity epoch boundary is now uncertain in the range of 0.7 to 1.0 million years.
One to three whole-rock samples from each of more than a dozen discrete plutonic intrusions in the east-central Sierra Nevada batholith have been analyzed for Sr87/Sr86 and Rb/Sr ratios to obtain information on initial Sr87 abundances.
The initial Sr87/Sr86 ratios in the rock magmas forming this province appear to have been in the range 0.7073 ± .0010 in the majority of cases. This range is definitely higher than that found for modern alkali-type and tholeiite-type basalt magmas of oceanic regions, which commonly range between 0.703 and 0.705. However, it is much lower than the average Sr87/Sr86 ratios found in Precambrian sialic regions which range from 0.71 to 0.73. It seems clear therefore that the Sierra Nevada magmas were not derived solely either from the typical source regions of oceanic basalt or from the melting of ancient crustal sial. It is possible that these magmas represent a mixture of oceanic basalt and crustal sial, as would be the case of anatexis in a geosyncline containing much volcanic material of fairly recent origin and some terrigenous sialic detritus. They may instead be of mantle derivation with admixtures of crustal material assimilated during their rise.
The whole-rock Rb-Sr age results derivec from the study indicate that the Lamarck and Mount Givens Granodiorites and the alaskite of Evolution Basin and porphyritic biotite granite of Dinkey Lakes form a younger group of intrusive rocks of 90 ± 10 m.y. Although the sampling was not designed for isochron age studies, it appears that most of the remaining rock units are considerably older.

All strains oxidized glucose and gluconate, produced NH3 from 1 % peptone, grew at 6, 12, 20 and 30° and produced cytochrome oxidase. Lipase was produced by 17 of the strains, while 15 produced gelatinase, and 16 produced fluorescent pigment. These and other characteristics used to identify fish-spoilage pseudomonads are also useful for identification of fish-pathogenic pseudomonads. Species determinations from the present data were not attempted. However, from previously published data on speciation of Pseudomonas, most of the 20 strains appeared to be closely related to or identical with P. fluorescens.

This work requires the production of numerous individual series of lake herring, lake whitefish, and several species of chubs from parent fish of positively known identity. The offspring of individual pairs or groups of fish must be held in individual tanks from the time they hatch until they reach maturity. One of the important problems in this project has been the poor growth of most fish. Though some have grown well, their growth has been less than that of the same species in nature, and a few fish from each hatch have grown very slowly. Irregularity of feeding may contribute to the slow growth of laboratory fish. The hatchery caretaker feeds them several times during his 8-hour workday, but they must go without food during the remaining 16 hours. The high metabolic rate of small fish, however, appears to make them strongly inclined toward almost continual feeding. Belief that greater, more regular food consumption would result from a mechanical feeder providing a continuous supply of food over a longer period of the day led to development of the equipment described in this paper.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Progressive Fish-Culturist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor & Francis","publisherLocation":"London, UK","doi":"10.1577/1548-8640(1965)27[173:AFFSFH]2.0.CO;2","collaboration":"Out-of-print","usgsCitation":"Joeris, L.S., 1965, Automatic feeder for small fish held in tanks: Progressive Fish-Culturist, v. 27, no. 3, p. 173-174, https://doi.org/10.1577/1548-8640(1965)27[173:AFFSFH]2.0.CO;2.","productDescription":"2 p.","startPage":"173","endPage":"174","numberOfPages":"2","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133297,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":267037,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/1548-8640(1965)27[173:AFFSFH]2.0.CO;2"}],"volume":"27","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa8e4b07f02db667528","contributors":{"authors":[{"text":"Joeris, Leonard S.","contributorId":104430,"corporation":false,"usgs":true,"family":"Joeris","given":"Leonard","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":308323,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":1013697,"text":"1013697 - 1965 - Two new species of Plistophoroa (Microsporidea) from North American fish with a synopsis of Microsporidea of freshwater and euryhaline fishes","interactions":[],"lastModifiedDate":"2025-05-09T15:50:14.948968","indexId":"1013697","displayToPublicDate":"1965-01-01T00:00:00","publicationYear":"1965","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2434,"text":"Journal of Protozoology","active":true,"publicationSubtype":{"id":10}},"title":"Two new species of Plistophoroa (Microsporidea) from North American fish with a synopsis of Microsporidea of freshwater and euryhaline fishes","docAbstract":"Two new species of Microsporidea, Plistophora salmonae from steelhead and rainbow trout (Salmo gairdntri) and Plistophora crpedianar from gizzard shad (Dorosoma cepedianum) are described.

This study is based on 3,705 fish collected on a reef south of Isle Royale near the eastern end. The mean lengths of humper trout from commercial gill nets were smaller than those of lean lake trout. Members of age-groups VII, VIII, and IX represented 81.5 per cent of the commercial humper catch. The body-scale relation was described by two intersecting straight lines. The weight of humper trout increased as the 3.282 power of the length. Growth in length was slow and ranged from 1.6 to 3.5 inches per year. Annual increments were greatest in the first, sixth, and seventh years. Growth in weight was also slow but increased each year. Humper trout became legal (1 1/2 pounds) in the eighth year of life and reached 5 pounds in 11 years. All fish longer than 19.1 inches and older than age-group VIII were mature; the shortest mature fish were: males, 12.7 inches; females, 14.7 inches. At minimum legal size, 98 per cent of the males and 56 per cent of the females were mature. Humper trout produced an average of 1,351 eggs per fish or 516 per pound.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor & Francis","publisherLocation":"London, UK","doi":"10.1577/1548-8659(1965)94[75:AGMAFO]2.0.CO;2","collaboration":"Out-of-print","usgsCitation":"Rahrer, J.F., 1965, Age, growth, maturity, and fecundity of 'humper' lake trout, Isle Royale, Lake Superior: Transactions of the American Fisheries Society, v. 94, no. 1, p. 75-83, https://doi.org/10.1577/1548-8659(1965)94[75:AGMAFO]2.0.CO;2.","productDescription":"9 p.","startPage":"75","endPage":"83","numberOfPages":"9","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133467,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266935,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/1548-8659(1965)94[75:AGMAFO]2.0.CO;2"}],"volume":"94","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae3e4b07f02db68927e","contributors":{"authors":[{"text":"Rahrer, Jerold F.","contributorId":76679,"corporation":false,"usgs":true,"family":"Rahrer","given":"Jerold","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":308434,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70010521,"text":"70010521 - 1965 - Eocene and miocene rocks off the northeastern coast of the United States","interactions":[],"lastModifiedDate":"2020-11-24T00:26:49.155915","indexId":"70010521","displayToPublicDate":"1965-01-01T00:00:00","publicationYear":"1965","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1372,"text":"Deep-Sea Research and Oceanographic Abstracts","active":true,"publicationSubtype":{"id":10}},"title":"Eocene and miocene rocks off the northeastern coast of the United States","docAbstract":"A grab sample from a depth of 1675 m at a point south of Cape Cod contains early Eocene planktonic Foraminifera and is correlated with the Globorotalia rex zone of Trinidad.

The large amount of attention recently being given to water shortage and the expected rapid increase in demand for water is probably to some extent clouded because there are certain simple facts about water availability and water use which, though readily available, are not generally either known or understood.
Probably most people react to information in the public press about present and possible future water shortages with the thought that it is going to be more difficult in the future to supply the ordinary household with water for drinking, washing, and tbe culinary arts. As a matter of fact that may be true to some extent, but it is not the salient aspect.

By a dilutionaddition modification of the flame-spectrophotometric method, sodium and potassium have been determined in 40 specimens of alpine ultramafic rocks. Samples represent six regions in the United States and one in Australia, and include dunite, peridotite, pyroxenite, and their variably serpentinized and metamorphosed derivatives.
The median value found for Na2O is 0.004 per cent, and the range of Na2O is 0.001–0.19. The median value for K2O is 0.0034 per cent and the range is 0.001–0.031 per cent. Alkali concentrations are below 0.01 per cent Na2O in 28 samples and below 0.01 per cent K2O in 35.
Derivation of basalt magma from upper-mantle material similar to such ultramafic rocks, as has been postulated, is precluded by the relative amounts of sodium and potassium, which are from 200 to 600 times more abundant in basalt than in the ultramafic rocks. Similar factors apply to a number of other elements. No reasonable process could produce such concentrations in, for example, tens of thousands of cubic miles of uniform tholeiitic basalt. The ultramafic rocks might have originated either as magmatic crystal precipitates or as mantle residues left after fusion and removal of basaltic magma. Injection of ultramafic rocks to exposed positions is tectonic rather than magmatic.
The Redwood Falls area includes about 80 square miles in southwestern Minnesota and is about 100 miles west of Minneapolis and St. Paul. Its surface is a gently undulating glacial-drift plain, interrupted in part by the large Minnesota River valley and the tributary Redwood River valley. The drift plain was laid down by the Des Moines lobe of the Wisconsin Glaciation and consists chiefly of ground moraine and several subdued recessional moraines. The glacial drift rests either on Precambrian gneiss or on thin patches of Cretaceous sedimentary strata that overlie the Precambrian bedrock.
\nThe glacial drift consists principally of till and some outwash and ranges in thickness from 0 to about 260 feet. It is the chief source of ground water, yielding small supplies almost anywhere in the area and large supplies in at least two places. Where the drift is absent, thin, or impermeable, small yields commonly are obtained from the Precambrian bedrock.
\nThe most notable aquifers in the area are three buried outwash deposits that are associated with a conspicuous southeastward-trending buried bedrock valley. The tops of the aquifers occur about 70,120, and 200 feet below the land surface, and their maximum known thicknesses are about 25, 55, and 45 feet, respectively. The aquifers are confined largely by relatively impermeable till; however, owing to the movement of water through the till, the drift may be regarded as a hydraulic unit.
\nThe main source of recharge to the ground-water reservoir is local precipitation, and most of the natural discharge is by evapotranspiration. The water table ranges in depth from 0 to about 30 feet below the land surface.
\nAquifer tests were made on the three outwash aquifers to determine their hydraulic characteristics. The coefficient of transmissibility (T) of the 200-foot aquifer is about 126,000 gpd (gallons per day) per ft, and the coefficient of storage (8) is about 0.0002. The T and S values of the 120-foot aquifer are about the same as for the 200-foot aquifer. For the 70-foot aquifer the value of T is about 70,000 gpd per ft, and S is about 0.0007. The data suggest that when the artesian head in the aquifers is lowered by pumping, recharge is induced by leakage from the confining beds.
\nThe 120-foot aquifer is considered the best known source of ground water In the area. The city of Redwood Falls has used this aquifer for its water supply since August 1955 and, in 1960, pumped about 106 million gallons from it. The water level in the aquifer had stabilized by late 1956; considerable additional water probably can be obtained from the aquifer. Although the 70-foot aquifer is not as extensive or as thick as the one at 120 feet, large amounts of water probably can be obtained from this aquifer also. The 200-foot aquifer is narrow, elongate, and irregular in form and appears to be very permeable only locally.
\nChemical analyses show that water from the glacial-drift aquifers is primarily of the bicarbonate type, is hard, and contains an excessive amount of iron. In places water from the Precambrian bedrock is much softer than water from the drift.

Two military bases are in the area; \r\nAnchorage is the largest city in Alaska and the chief transportation center \r\nfor this part of the State. \r\nThe bedrock in the Anchorage area is chiefly Tertiary shale in the lowland \r\nand metamorphic rocks of Mesozoic age beneath the adjacent mountain \r\nslopes. Glacial drift which underlies nearly the entire area has an average \r\nthickness of several hundred feet and appears to include at least five sheets \r\nof deposits, two of which are exposed. The drift consists of till, outwash stream and lake deposits (sand and gravel), and estuarine (and lake) deposits \r\n(clay and silt). The stratigraphy and lateral distribution of the deposits are \r\ncomplex, but data at hand s, how that the thickest deposits, including all the \r\nestuarine and lake sediment and most of the stream-deposited sediment, \r\nare beneath the lowland away from the mountain wall, and that the deposits \r\nnear the mountains are till and subordinate outwash sediments. \r\nDeposits of sand and gravel laid down by outwash streams in channels and \r\non outwash plains are the most important aquifers, and the only \r\nones which yield large quantities of ground water from single beds. Thin \r\nlayers of sandy or gravelly material in till are also important aquifers although they yield relatively small quantities of water. Bedded sand and \r\nsilt associated with the estuarine and lake(?) clay commonly becomes unstable during drilling and pumping, and has been successfully developed in \r\nonly a few wells. Unconfined aquifers are extensive, but permeable saturated \r\nmaterial is thin in many places and water supplies available from them are \r\nsmall or undependable in those places. The most important aquifers are confined or artesian. Clay and till form the confining beds: the till is somewhat 'leaky' in many places. Near Anchorage the buried water-bearing \r\nbeds appear to be interconnected and to form a single artesian system. The \r\nwater table and piezometric surface slope from the mountain wall of the \r\nlowland toward the estuaries, and the flow of the ground water is in that \r\ndirection. The aquifers are recharged by the infiltration of precipitation \r\nat the land surface and of surface water through stream beds: near the mountains the artesian aquifers are probably recharged in part by percolation from \r\nthe water-table aquifer, and far from the mountains the water-table aquifer \r\nis probably recharged in part by upward flow from the underlying artesian \r\naquifers. In several valleys and in a few other places, in the lowland, artesian wells flow at the land surface. \r\nThe outwash sand and gravel are moderately to very permeable; most \r\nof the other water-bearing material are much less permeable. The co- efficient of transmissibility for some single beds of sandy gravel is as high \r\nas 60,000 to I00,000 gpd per ft (gallons per day per foot); for the entire \r\nsection of glacial drift at and near Anchorage it is believed to be of the \r\norder of 200,000 gpd per ft. Calculations based on this value for the total \r\nsection and on the slope of the piezometric surface indicate that in the \r\nimmediate vicinity of Anchorage about 5 million gpd flows through each \r\nmile-wide section of the drift (measured in a northeast-southwest direction, perpendicular to the direction of flow), under normal (nonpumping) conditions. Under conditions of continuous heavy pumping the slope of the piezometric surface is steepened, flow is increased, and additional recharge is induced. \r\n\r\nThe highest yield reported from a well in this area is 2.600 gpm (gallons per minute) with 35 feet of drawdown: the highest reported specific capacity is 180 gpm per ft of drawdown, for a well pumped at. 270 gpm. \r\n\r\nOnly a few wells in the area have been developed for high yields.

In good light, bright colors are visible through a 20-power spotting scope for more than 1 mile. Retention of collars was about 90 percent for 1 year and more than 80 percent for 2 years.

California","docAbstract":"Deposits of ferruginous nickeliferous lateritic soils formed by weathering in place of ultramafic rocks occur at several places in northwestern California and southwestern Oregon, mostly in the Klamath Mountains province. Most of the deposits have been derived from relatively fresh peridotite, although at least one deposit was formed on serpentinite. The accumulations of lateritic soil are on flat-lying to gently sloping surfaces in a terrain that has been extensively dissected and deeply entrenched.The thickness of the deposits ranges from a few feet to more than 50 feet, and may vary widely in any given deposit, for the bedrock surface is commonly highly irregular. The deposit at Nickel Mountain, Oregon, is unique, because it is the only one in which the nickel silicate, garnierite, is plentiful. At Nickel Mountain, garnierite, accompanied by abundant microcrystalline quartz, occurs in veinlike bodies and boxworks that lie at the base of the soil zone and persist in depth along joints and fractures into the underlying slightly weathered or fresh peridotite.Mineralogical studies and chemical analyses show that weathering of the ultramafic rocks destroyed olivine and much of the orthopyroxene and serpentine minerals. Secondary minerals formed are predominantly hydrated ferric oxides (goethite); minor amounts of a montmorillonite mineral, chlorite, and talc were also identified. The kaolin group and bauxite minerals were not found. Except for garnierite at the Nickel Mountain deposit, no nickel-bearing mineral was identified. Nickel may occur, however, in montmorillonite, chlorite, and talc where it substitutes for Mg to a limited extent; in serpentine minerals that were not destroyed by weathering; and possibly in combination with ferric hydroxides. Cobalt may also occur in the clay minerals and probably is associated with trace amounts of manganese oxide or hydroxides.The lateritic soils in northwestern California and southwestern Oregon are similar to soils formed by lateritic weathering of ultramafic rocks in Cuba, the Philippines, New Caledonia, and other tropical regions of the world. They have, however, a higher content of SiO 2 and MgO, and a lower content of Fe 2 O 3 than deposits formed in tropical climates. The California and Oregon deposits are considerably smaller and lower in average metal content which, because they are widely scattered in a rugged, relatively isolated terrain, makes them unpromising as likely reserves for commercial exploitation in the foreseeable future.Most of the deposits are regarded as having been formed by chemical weathering in a climate having alternating wet and dry seasons, probably similar to that prevailing today. Their age is uncertain but may range from post-Miocene to Pleistocene.
This discussion of the lithology and microfauna of the clastic facies of the Ecocene and Paleocene rocks of Florida is based mainly on data obtained from the study of many cores taken in the Oil City corporation Walton Land and Timber Co. well 1, Walton County, Fla. Although the fauna of the middle Eocene rocks in western Florida is composed mainly of species that have been reported from rocks of equivalent age in the western Gulf Coast, its distinctive species, and poor representation of a few species that are diagnostic in the western area. The assemblages of small Foraminifera in the lower Eocene rocks are composed, mainly, of specimens of species that have been described from outcrops of the Wilcox Group in Alabama. The microfauna of the clastic facies of the Paleocene in western Florida is informally called the \"Tamesi' Fauna\" in this report. This Fauna is particularly important because it contains abundant Glorotalia velasconesis, a diagnostic species of the Velasco (Paleocene) Formation of Mexico, is also diagnostic of the \"Tamesi fauna.\" On the basis of the environmental preference of Recent analogous pelagic forms, the preferential environment of the containing sediments, it is inferred that the \"Tamesi fauna\" developed in a subtropical, open sea environment.
The Effect of the temperature, salinity, bathymetry, and associated factors on the distribution of Recent pelagic species of Foraminifera has been discussed by several authors. Similar controls were probably effective during Paleocene time. The presence of certain species of pelagic Foraminifera in one Paleocene unit, and their absences in another, is therefore not necessarily an index to the relative position of the units in the vertical time sequence. The stratigraphic distribution of the benthonic species of the \"Tamesi Fauna\" in western Florida is usually accord with their stratigraphic distribution in the Paleocene beds in other parts of the Gulf coast. Consequently, on the basis of the foregoing enviromental and distributive data, it is suggested that the \"Tamesi Fauna\" of the clasttic lithofacies of the Paleocene in western Florida respresents an interval of geologic time that is equivalent to the represented by the Clayton, Porters Creek, and Naheola formations of Alqabama and Correlative stratigraphic units in other parts of the Gulf region. It is believed that the outer neritic Paleocene sediments of west Florida grade northward into the inner-neritic Paleocene sediments that crop out in Alabama. Fifty seven species of Foraminifera that are characteristic of the cored Paleocene section in the Walton well, and recorded from 37 other wells distributed across northwestern Florida and southern Georgia, are discussed and figured. Two species are describes as new: Epoides libertyensis and Cibicides libertyensis.

The maximum recorded trap life was 29 months, and the greatest estimated age was 36 months. Opossums did not enter traps readily, and the average period between consecutive captures was 31 days. Trap records indicated that opossums range over long, narrow areas rather than circular ones, probably associated with stream courses. Opossums begin to breed in Maryland in early February and young are found in the pouch until August. Evidently the first breeding period accounts for most of the young produced. The sex ratio of those trapped was slightly higher for males than females, but did not differ significantly from an expected sample from an even sex ratio. The trapping results indicated a production rate of from 4 to 5.4 young per adult female, but this is based on the assumption that young and adults have the same trap response. Opossums appear to favor low, damp woods rather than upland woods or open areas.

The fish tagged in June-July 1960 were mostly undersized (less than 17 inches long) whereas those captured on the spawning grounds and tagged in November 1959-61 were almost all legal size. Of the 374 recoveries (28.7 percent), nearly all were made during the first 2 years after tagging. The earliest returns were from fish which were among the largest when tagged. Over one-half of the recoveries were made within 5 miles of the tagging site; the greatest distance traveled by an individual was 25 miles. The fish tagged in June-July 1960 grew 1.6 inches the first season and 1.2 the second. Of 27 whitefish recaptured within 6 months from the November 1959-61 group, 17 (63 percent) had lost length (range from decrease 0.1 to 1.4 inches). Whitefish of the June-July group recaptured during the second growing season after tagging gave an exploitation rate of 22.6 percent. First-year returns from the November 1959-61 tagging gave an exploitation rate of 20.5 percent. The true exploitation rate probably is higher since no allowance has been made for tagging mortality, loss of tags, or unreported recaptures.

It is one of the least studied of the coregonines; the present report is but the second for Great Lakes waters. Commercial production in Lake Michigan has been tightly confined to the northern portion. The period 1924-30 showed the best production: 200,000 to 359,000 pounds. Since 1956, production has been around 10,000 pounds or less. The present age and growth study is based on 208 fish collected by gill net in December 1951. The relation between total length in inches (L) and the weight in ounces (W) is described by the equation log W = -2.7232 + 3.2940 log L. Age-group III made up 66.3 percent, and age-group IV, 20.6 percent of the sample; age-groups V, VI, and VII combined contributed only 5.9 percent. The average length for all fish in the sample was 14.5 inches. Growth was calculated from a previously published linear body-scale relation with an intercept of 1.1 inches on the axis of fish length. The increments of calculated length declined steadily from a maximum of 4.6 inches the first year to 1.0 inch the eighth. A 3-year-old Lake Michigan fish (12.3 inches) is as long as a 5-year-old Lake Superior fish, and an 8-year-old Lake Michigan fish (18.9 inches) is 0.9 inch longer than the oldest (12 years) from Lake Superior. The smallest mature males and females were in the length intervals 12.0-12.4 inches and 13.0-13.4 inches, respectively. All males over 1.4 inches and all females over 14.9 inches were mature. The youngest mature males were in age-group II; 36 percent of II-group males but none of the females were mature. All fish older than age-group III were mature.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor & Francis","publisherLocation":"London, UK","doi":"10.1577/1548-8659(1964)93[46:AAGOTR]2.0.CO;2","collaboration":"Out-of-print","usgsCitation":"Mraz, D., 1964, Age and growth of the round whitefish in Lake Michigan: Transactions of the American Fisheries Society, v. 93, no. 1, p. 46-52, https://doi.org/10.1577/1548-8659(1964)93[46:AAGOTR]2.0.CO;2.","productDescription":"7 p.","startPage":"46","endPage":"52","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":266922,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/1548-8659(1964)93[46:AAGOTR]2.0.CO;2"},{"id":132989,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"93","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae4e4b07f02db689b6b","contributors":{"authors":[{"text":"Mraz, Donald","contributorId":21502,"corporation":false,"usgs":true,"family":"Mraz","given":"Donald","email":"","affiliations":[],"preferred":false,"id":308378,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":1000316,"text":"1000316 - 1964 - Age, growth, sex ratio, and maturity of the whitefish in central Green Bay and adjacent waters of Lake Michigan","interactions":[],"lastModifiedDate":"2016-02-25T15:28:23","indexId":"1000316","displayToPublicDate":"1964-01-01T00:00:00","publicationYear":"1964","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1664,"text":"Fishery Bulletin of the U.S. Fish and Wildlife Service","active":true,"publicationSubtype":{"id":10}},"title":"Age, growth, sex ratio, and maturity of the whitefish in central Green Bay and adjacent waters of Lake Michigan","docAbstract":"This study is based on 1,023 whitefish, Coregonus clupeaformis (Mitchill)--819 in seven samples from five localitites in central Green Bay in 1948-49 and 1851-52 and 204 in a single 1948 collection from northwestern Lake Michigan proper. Records of age indicated unusual strength for only one year class--1943 which strongly dominated the 1948 sample from Lake Michigan and the 1949 sample from Green Bay and was well represented in the 1948 collection from green Bay. Collection of 1951-52 without exception were dominated by age group III. Length distributions of samples varied widely according to the age composition. Among fish more than 2 years old, the length distributions of age groups overlapped broadly. Several 1-inch intervals included fish of four age groups. The length-weight relation varied considerably among central Green Bay samples, but differences among localitites were nearly equalled by the year-to-year difference at a single locality. Lake Michigan whitefish were generally lighter than those from Green Bay. Weight increased to the 3.386 power of length in Green Bay (combined samples) and the 3.359 power in Lake Michigan. Growth in length, calculated by direct proportion from diameter measurements of growth fields on scales, differed among localities in central Green Bay and between samples of different years at a single locality. If permanent locality differences exist they are not large and can be obscured by the evident annual fluctuations of growth. The grand average calculated length of Green Bay whitefish (combined collections) exceeded that of Lake Michigan fish in all years of life. The advantage was greatest (2.2 inches) at 3 years (calculated lengths of 16.0 inches and 13.8 inches) and subsequently declined to 0.5 inch at 9 years (lengths of 24.6 and 24.1 inches). Both groups reached the minimum legal length of 17 inches during the fourth growing season. Green Bay whitefish also had the larger calculated weights. The advantage reached 9.3 ounces in 3 years (calculated weights of 22.4 and 13.1 ounces). In years of life 4-9, the weight advantage over Lake Michigan fish ranged from 8.7 ounces, (seventh year; weights of 74.4 and 65.7 ounces) to 12.2 ounces (ninth year; weights of 96.2 and 84.0 ounces). Comparison of growth of whitefish at four localities in northern Lake Michigan indicates that fastest growth is in central Green Bay and slowest near the Fox Islands. Growth is intermediate and similar in northwestern Lake Michigan proper and sorthern Green Bay. Youngest mature male whitefish in green Bay belonged to age group II and youngest mature females to age group III. All IV-group fish were mature. Shortest mature males were at 14.5-14.9 inches and shortest mature females at 16.5-16.9 inches. All males longer than 17.9 inches and all females longer than 18.4 inches were mature.

Although specific determination of these isolates was unsuccessful, they were separated into three groups according to morphological and cultural characteristics. Rhizoctonia solani Kuehn was isolated in rare instances. In inoculation studies, isolates of R. solani were pathogenic to P. pectinatus, whereas inoculations with Pythium spp. proved inconclusive, even though one group of isolates exhibited pathogenic tendencies.
