Download or read book Clinical Methods for the Assessment of the Effects of Environmental Stress on Fish Health written by Gary A. Wedemeyer and published by . This book was released on 1977 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clinical methods are presented for biological monitoring of hatchery and native fish populations to assess the effects of environmental stress on fish health. The choice of methods is based on the experience of the authors and the judgment of colleagues at fishery laboratories of the U.S. Fish and Wildlife Service. Detailed analysis methods, together with guidelines for sample collection and for the intrepretation of results, are given for tests on blood (cell counts, chloride, cholesterol, clotting time, cortisol, glucose, hematocrit, hemoglobin, lactic acid, methemoglobin, osmolality, and total protein); water (ammonia and nitrate content); and liver and muscle (glycogen content).

Available in PDF, EPUB and Kindle. Book excerpt: This history of the salmon in the Great Lakes describes the decline and extinction of the Atlantic salmon in Lake Ontario in the 1800's; the failure to establish, by salmon culture, permanent or sizable populations of Atlantic or Pacific salmon in any of the Great Lakes in 1867-1965; and the success of plantings of coho and chinook salmon in the Great Lakes, 1966-1970 -- particularly in Lake Michigan.
Download or read book Atlantic Salmon Salmo Salar written by Florence T. Wright and published by . This book was released on 1975 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: North American stocks of Atlantic salmon (Salmo salar) have been declining. One measure being employed to reverse that trend is increased hatchery production. As with husbandry of other animals, intensive rearing is usually associated with higher than normal health risks. Research on diseases of Atlantic salmon can help prevent, reduce, or otherwise control mortality due to problem parasites, infections, and other diseases. For planning of research as well as for diagnostic work, health management, and husbandry, published information on diseases of the Atlantic salmon must be readily available. Inasmuch as the literature is widely scattered, the purpose of this work is to compile a bibliography from international sources on the diseases (detection, diagnosis, identification, and control) of Atlantic salmon. Most of the references are arranged alphabetically by author, either have been annotated by the staff of the Eastern Fish Disease Laboratory, or are abstracts by the author.

Download or read book Biology of the Redtail Surfperch Amphistichus Rhodoterus from the Central Oregon Coast written by Donald E. Bennett and published by . This book was released on 1977 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data on certain aspects of the life history of the redtail surfperch were collected along the central coast of Oregon, from April 1967 through April 1969. Annulus formation occured during February through June, usually earlier in young than in older fish. Mating occurred from late December to early January, and the young were born from July through September. The number of embryos per female ranged from 1 to 39 (mean 13.3) and increased linearly with the length and weight of the females. Food of the fish from the surf zone included crustaceans (by far the most important group in both frequency of occurrence and total volume) and (in order of decreasing importance) fishes, mollusks, and polychaetes. Parasites of the redtail surfperch were immature nematodes (Anisakinae) ; the digenetic trematode Genitocotyle acirra; the monogenetic trematode, Diclidophora sp.; and the copepods, Caligus sp., Clavella sp., and Argulus catostomi.

Book excerpt: Prediction equations correlating density of fingerling rainbow trout with growth, yield, and food use efficiency indicated that ammonia nitrogen resulting from high fish densities wes responsible for reductions in all three factors. These predictable density-dependent responses present fish-culturists with alternatives of density selection for evaluation and attainment of specific goals. In examples, fish-culturists, by manipulating density, could achieve rapid growth, produce the maximum weight possible, balance yield with cost, optimize fish quality, or combine two or more of these goals.
