The commercial fishery for walleyes (Stizostedion vitreum vitreum) in Lake Erie virtually collapsed in the late 1950's. The extreme decline in production was attributed primarily to a succession of weak year-classes, caused by habitat deterioration (increased water temperatures, enrichment, and pollution) in western Lake Erie. Unusually high fishing intensity and high yields of walleyes in the mid-1950's contributed to the collapse.Annual lakewide production of walleyes dropped from a record high of 15 million lb in 1956 to a record low of 717,000 lb in 1962. Canadian catches exceeded those of the United States only during the high production years of 1956–58; U.S. fishermen took 71% of the total catch in 1915–62.On the basis of the numbers of fish of the various year-classes in the fall trapnet samples at Sandusky, Ohio, in 1943–62, all but one of the 1942–52 year-classes were above average strength, and all but one of the 1953–61 year-classes were below average. Fish of the 1953–61 year-classes grew much faster than those of the 1942–52 year-classes. The strong 1948 year-class was followed by a series of progressively weaker year-classes until 1958; year-class strengths remained low through 1962.

The two insecticides found in all Great Lakes fish have been DDT (DDT, DDD, DDE) and dieldrin. Fish from Lake Michigan contain from 2 to 7 times as much of these insecticides as those from the other Great Lakes. Insecticide levels calculated on a whole-fish basis show a marked difference from species to species. Within a species there is also an increase in DDT and dieldrin levels with an increase in size. If these insecticide levels are, however, calculated as ppm of insecticide in the extractable fish oil, the differences in concentration between species and the differences between size groups becomes considerably less. Laboratory experiments indicate that fish can build up concentrations of DDT and dieldrin at the parts-per-million level from parts-per-trillion concentrations in the water.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pesticides Monitoring Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Out-of-print","usgsCitation":"Reinert, R.E., 1970, Pesticide concentrations in Great Lakes fish: Pesticides Monitoring Journal, v. 3, no. 4, p. 233-240.","productDescription":"p. 233-240","startPage":"233","endPage":"240","numberOfPages":"7","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":130476,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269747,"type":{"id":11,"text":"Document"},"url":"https://biodiversitylibrary.org/page/26094207"}],"volume":"3","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae0e4b07f02db68838e","contributors":{"authors":[{"text":"Reinert, Robert E.","contributorId":101214,"corporation":false,"usgs":true,"family":"Reinert","given":"Robert","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":308382,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":1000384,"text":"1000384 - 1970 - Species interactions of the alewife in the Great Lakes","interactions":[],"lastModifiedDate":"2016-03-14T13:57:04","indexId":"1000384","displayToPublicDate":"1970-01-01T00:00:00","publicationYear":"1970","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3624,"text":"Transactions of the American Fisheries Society","active":true,"publicationSubtype":{"id":10}},"title":"Species interactions of the alewife in the Great Lakes","docAbstract":"The alewife (Alosa pseudoharengus) has caused serious problems in the Great Lakes for almost 100 years. It entered Lake Ontario in abundance via the Erie Canal during the 1860's when major piscivores were declining, and became the dominant species in the lake during the 1870's. The alewife subsequently spread throughout the Great Lakes and became the dominant species in Lakes Huron and Michigan as major piscivores declined. In lakes where it became extremely abundant, the shallow-water planktivores declined in the first decade after alewife establishment, the minor piscivores increased then declined in the second decade, and the deep-water planktivores declined in the third decade. The consequence has been a general reduction in fishery productivity. Rehabilitation will require extreme reduction of the alewife, and restoration of an interacting complex of deep- and shallow-water forage species, and minor and major piscivores, either by reestablishing species affected by the alewife, or by the introduction of new species that can thrive under the new ecological conditions of the lakes.

During metamorphosis, the eye enlarged greatly, the snout and mouth region changed from a fleshy hood enclosing a sieve apparatus to a large sucking disc, the nasopore membrane and the branchial area shrank, the branchiopores changed in shape, the general color changed from dark brown and yellow to an intense blue-black dorsally and white ventrally, and the total length increased. Metamorphosis began in early to mid-July and did not take place after August. The duration of external metamorphosis was about 3 months for lampreys transforming under natural conditions. The mean lengths of metamorphosing lampreys from tributaries of lakes Superior and Michigan were 145 and 136 mm, respectively.

Deterioration of the caudal fin was frequently accompanied by degeneration of the dorsal and anal fins. Degenerate fins were not found on other species nor on older alewives, with the exception of one known yearling alewife at Waukegan and possibly a few of the larger fish at Milwaukee.

Growth varied considerably among year classes. Larvae of the 1963 year class were slightly longer at age II and 30% longer at age III than the III-group larvae of the 1960 year class. About 6% of 558 III-group lampreys of the 1963 year class had metamorphosed by 17 August 1966. Although the sex ratio of larvae was about 1:1, 97% of the metamorphosed lampreys were males. The distribution of pigmentation on the caudal fin and upper lip in ammocoetes less than 40 mm long permitted accurate and rapid separation of northern brook lampreys from the sea lamprey, Petromyzon marinus.

Three critical periods in the embryogenesis of hybrid lampreys were between stages 8 and 9, among stages 10, 11, and 12, and at stage 15. Embryonic development in hybrid lamprey embryos is basically identical to that of controls and is identical to that of the sea lamprey (Petromyzon marinus). Synchrony of development was observed among stages of viable hybrids and their controls but lethal hybrids generally did not maintain such synchrony. The derivative species concept has been confirmed experimentally. Questions have been raised concerning some evidence cited in behalf of the appropriateness of the concept that nonparasitic lampreys are the derived species.

The restricted distribution and age of the maria are in marked contrast to the apparently random distribution in time and place of the circular basins, some of which contain mare fillings. The circular basins are believed to be impact scars, and the maria to be volcanic fills which in each case are younger than the structures they fill.
Twenty-nine circular basins 300 km wide or wider are recognized. They are placed in an age sequence because successive stages of degradation can be recognized from the fresh Orientale basin to the almost obliterated basin containing Mare Australe.
The maria were emplaced during a short span of lunar history, although some light plains of the highlands may be older maria lightened through age. The present maria are topographically low, tend to be associated with large circular basins, and lie in a crude global belt of regional concentrations; 94% are on the hemisphere facing the Earth. Possible explanations offered for these patterns of mare distribution include impact-induced volcanism, volcanic extrusion to a hydrostatic level, isostatic compensation, lateral heterogeneity in the lunar interior, subcrustal convection, and volcanism due to disruption by Earth's gravity.

Umatilla is 3.2 kilometers below McNary Dam. Accumulations of radionuclides in the Pasco to Umatilla reach estimated by the two methods agree within about 8%. In October 1965 approximately 16,000 curies of gamma emitting radionuclides were resident in bed sediments of the river between the Hanford reactors and McNary Dam. Concentrations and accumulations of chromium-51, zinc-65, cobalt-60, manganese-54, and scandium-46 generally are much higher near McNary Dam than they are in the vicinity of the reactors. These changes are caused by an increase downstream from the reactors in the proportion of the bed sediment that is fine grained and the proportions of the transported zinc, cobalt, manganese, and scandium radionuclides associated with sediment particles.

Strain I (nonvirulent) produced no change in the relative concentration of serum components. Strains II (oral canker) and III (Jones' Barn) produced decreases in albumin and alpha globulins, and increases in beta and gamma globulins between the 7th and 20th days post infection. Birds infected with strain II began to return to normal by the 20th day, while all those infected with strain III were dead between 10 and 14 days post infection.
Two serum protein patterns resulted from infection of immune birds with the Jones' Barn strain. One showed no change in relative protein concentrations and no tissue invasion by the parasite while the other was similar to that seen in nonimmune birds infected with a strain producing oral canker. These also showed evidence of tissue invasion by the parasite.
It was concluded that tissue invasion was necessary to evoke a quantitative change in serum protein concentrations.

Thomomys talpoides. in the western United States. It also occurs secondarily in other wild rodents that come into close contact with pocket gophers.
Field studies disclosed pursuit, mating, and ovipositing at an aggregation site near Monte Cristo, Utah. Eggs were individually attached to fibrous roots suspended from the roof of shallow gopher burrows. This refinement of the host-parasite relationship has not previously been described for other North American cuterebrids.
In the laboratory, 3 gravid females produced 186–357 viable eggs; about 85% were induced to hatch or hatched spontaneously after 12 days. Dissection of 1 of the females revealed another 886 eggs, for a total of 1243.
Larvae were artificially introduced and developed in deer mice (Peromyscus maniculatus). domestic mice (Mus musculus). hamsters (Mesocricetus auratus), and meadow voles (Microtus montanus). The domestic rabbit (Oryctolagus cuniculus) appeared refractory. The rate and success of development in the 4 rodent species was variable, but terminal larval development averaged about 22 days. Warbles appeared after 8 days in the rodents, and the majority of the cysts occurred in the posterior dorsal region.
On the basis of larval characteristics, C. polita and C. thomomuris appear to be independent, valid species, though they share a common host.

Forms that decline sharply were the largest cladocerans (Leptodora kindtii, Daphnia galeata, and D. retrocurva), the largest calanoid copepods (Limnocalanus macrurus, Epischura lacustris, and Diaptomus sicilis), and the largest cyclopoid copepod (Mesocyclops edax). Two of these, D. galeata and M. edax (both abundant in 1954), became extremely rare. Certain medium-sized or small species increased in numbers: Daphnia longiremis, Holopedium gibberum, Polyphemus pediculus, Bosmina longirostris, Bosmina coregoni, Ceriodaphnia sp., Cyclops bicuspidatus, Cyclops vernalis, and Diaptomus ashlandi. Evidence is strong that the changes were due to selective predation by alewives. The alewife was uncommon in southeastern Lake Michigan in 1954 but had increased to enormous proportions by 1966; there was a massive dieoff in spring 1967, and abundance remained relatively low in 1968. The composition of zooplankton populations in 1968 generally had shifted back toward that of 1954, although D. galeata and M. edax remained rare. The average size, and size at onset of maturity, of D. retrocurva decreased noticeably between 1954 and 1966 but increased between 1966 and 1968.

The percentages of females increased from 72% of the bloaters samples in 1928-32 to 95% in 1963, and ranged from 94 to 97% in 1964-69. The unusual predominance of females was established at an early age, unquestionably before age III. Bloaters grew faster in southeastern Lake Michigan in 1960-69 than in 1954 and earlier, and were less abundant there in 1966-69 than in 1962-65. The average age of female bloaters from trawls increased from 3.5 years in 1964 to 6.0 years in 1969. The increase in average age followed a heavy drop in fishing intensity and was accompanied by a decline in recruitment. The percentage representation of age-III bloaters, for example, decreased from 62.4% in 1964 to 2.5% in 1969. The changes in biological characteristics of the bloater may partly be symptoms of a fish population that is poorly adjusted to the changing ecology of Lake Michigan.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Biology of coregonid fishes","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Univ of Manitoba Press","publisherLocation":"Winnipeg, Canada","usgsCitation":"Brown, E.H., 1970, Extreme female predominance in the bloater (Coregonus hoyi) of Lake Michigan in the 1960's, chap. of Biology of coregonid fishes, p. 501-514.","productDescription":"p. 501-514","startPage":"501","endPage":"514","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":126954,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a06e4b07f02db5f89b8","contributors":{"editors":[{"text":"Lindsey, C.C.","contributorId":112003,"corporation":false,"usgs":true,"family":"Lindsey","given":"C.C.","email":"","affiliations":[],"preferred":false,"id":504058,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Woods, C.S.","contributorId":111533,"corporation":false,"usgs":true,"family":"Woods","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":504057,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Brown, Edward H.

Some fishes of former economic importance have become commercially extinct. Several species apparently have been extirpated, especially in the tributaries. It is believed that further changes in the abundance of other species will occur in the near future. This publication consolidates the confirmed records of fish species for Lake Erie and its tributaries. One hundred and thirty-eight species of fishes are listed and, where appropriate, brief comments on present and past distribution and abundance and economic status are given. Selected references are listed as additional sources of information for each species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ohio Journal of Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ohio Academy of Science","collaboration":"Out-of-print","usgsCitation":"Van Meter, H.D., and Trautman, M.B., 1970, An annotated list of the fishes of Lake Erie and its tributary waters exclusive of the Detroit River: Ohio Journal of Science, v. 70, no. 2, p. 65-78.","productDescription":"14 p.","startPage":"65","endPage":"78","numberOfPages":"14","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":131761,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266963,"type":{"id":15,"text":"Index Page"},"url":"https://hdl.handle.net/1811/5521"}],"volume":"70","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adae4b07f02db6857b2","contributors":{"authors":[{"text":"Van Meter, Harry D.","contributorId":36887,"corporation":false,"usgs":true,"family":"Van Meter","given":"Harry","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":308572,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Trautman, Milton B.","contributorId":19120,"corporation":false,"usgs":true,"family":"Trautman","given":"Milton","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":308571,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":1013851,"text":"1013851 - 1970 - Effects of gossypol on rainbow trout Salmo gairdneri Richardson","interactions":[],"lastModifiedDate":"2025-02-04T16:29:23.730459","indexId":"1013851","displayToPublicDate":"1970-01-01T00:00:00","publicationYear":"1970","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2285,"text":"Journal of Fish Biology","active":true,"publicationSubtype":{"id":10}},"title":"Effects of gossypol on rainbow trout Salmo gairdneri Richardson","docAbstract":"Rainbow trout were fed gossypol acetate or cottonseed meals containing gossypol for 14 months.
