Geology and ground-water resources of the islands of Lanai and Kahoolawe, Hawaii
Harold T. Stearns, Gordon Andrew Macdonald, Joel Howard Swartz
1940, Bulletin 6
Lanai lies 59 miles southeast of Honolulu, Oahu, has an area of 141 square miles, and is 3,370 feet high. (See fig. 1 and pl. 1.) Lanai City is the only town of importance. The island produces pineapples and cattle. The surface above about 1,200 feet is generally covered with...
Tagging experiments with lake trout, whitefish, and other species of fish from Lake Michigan
Oliver H. Smith, John Van Oosten
1940, Transactions of the American Fisheries Society (69) 63-84
A total of 2,902 Lake Michigan fish was tagged and released, 48.8 per cent of which were lake trout and 85 per cent lake trout, lake herring, and whitefish. A total of 388 fish or 13.4 per cent was recaptured. The percentages of returns indicated a tremendous fishing intensity for...
Scyphidia micropteri, a new protozoan parasite of largemouth and smallmouth black bass
E. W. Surber
1940, Transactions of the American Fisheries Society (69) 169-175
A small urn‐shaped peritrichous protozoan, apparently an undescribed species, was found on the gills and bodies of largemouth and smallmouth black bass in ponds at Leetown, West Virginia. A heavy mortality among a lot of fingerling largemouth bass probably resulted from suffocation due to the organisms on the gills. Specimens...
Neascus infection of black-head, blunt-nosed, and other forage minnows
G. E. Klak
1940, Transactions of the American Fisheries Society (69) 273-278
Black‐head, blunt‐nosed, and other minnows were found infested with encysted flatworms in ponds at Leetown, West Virginia. The mortality in a 2.2‐acre pond stocked with 100,000 black‐head minnows was about 250 per day during four weeks of observation. Heavy infestations caused sterility in the minnows. The cyst and parasite are...
Ridge-making thin sandstone in Frederick County, Virginia: Chapter C
R.S. Edmundson
1939, Book chapter, Contributions to Virginia Geology--II
It is generally recognized that massive thick-bedded sandstones and relatively weak shales and soluble limestones form characteristic surface features. The uncommon effect of a thin argillaceous sandstone in producing ridges in an area in northern Virginia, in which the writer has recently done detailed field work, is briefly described in...
Simplified methods for the prolonged treatment of fish diseases
F. F. Fish
1939, Transactions of the American Fisheries Society (68) 178-187
The prevention or control of epidemics of fish diseases by applying a disinfecting solution in a uniform concentration directly to the water supply of a fish pond or trough for a definite period of time has been exceedingly slow in development. In so far as can be determined, the original...
Notes on the effect of low temperature upon eyed eggs
F. F. Fish, R.E. Burrows
1939, Progressive Fish-Culturist (6) 28-31
The question has sometimes been raised whether or not any permanent injury may be inflicted upon fish eggs through their subjection to the relatively low temperatures prevailing in egg cases during shipment. This question may be argued in either direction purely upon the basis of indirect evidence which can be summoned...
