Book Description
Thermal, oxygen and conductance characteristics are described for two impoundments of the White River in Arkansas and Missouri, from 1963 to 1967. Warming of hypolimnetic waters in Beaver lagged behind that of Bull Shoals owing to epilimnetic turbidity. Annual heat budgets for Bull Shoals were consistently higher than those of Beaver Reservoir; when adjusted for mean depth, heat budgets did not differ significantly from those of natural lakes. Successive annual increases in water transparency, depth of thermocline formation, and oxygen content of underlying waters were evident in new Beaver Reservoir. Oxygen distribution graded from clinograde through orthograde in both reservoirs. Irregular patterns of oxygen distribution were related to the manner in which winter-stored water was depleted or retained. Comparison with other waters for nearly all measurements realted to biological productivity suggests an oligomesotrophic classification. Average conductance of Beaver Reservoir was inversely correlated with inflow volume; in Bull Shoals Reservoir, highest values were in periods of high inflow and water exchange.

Book Description
Studies on two hemoflagellates of fish were carried out to determine biological parameters: host range, vector relations, in vivo culture, in vitro culture, pathogenicit, and cryogenic preservation.
Author: Florence T. Wright Publisher: ISBN: Category : Atlantic salmon Languages : en Pages : 28
Book Description
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.

Book Description
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.

Book Description
Partial antibody characterization indicates that specific channel catfish immunoglobulins are macroglobulins with characteristics like those of most fish immunoglobulins and similar to those of human immunoglobulin-M.
