Creator:: Lomnicky, Gregg A.
Abstract:: Laboratory stream communities in simulated old growth second order streams were sampled June 1984 and June 1985 to advance an understanding of their organization and development, and their response to an environmental perturbance, the toxicant dieldrin. An interpenetrating hierarchical view of habitats and community subsystems was taken to conceptualize community...

Abstract:: Effects of diet on food energy utilization by grass carp fed aquatic plants or formulated diets with varied lipid sources and levels are presented in three manuscripts. Significant effects of diet on food consumption, digestion, growth and muscle fatty acid (FA) composition of fingerling diploid grass carp fed aquatic macrophytes...

Creator:: Alabdulsalaam, Thabit Z.
Abstract:: The purpose of this research was to examine the effects of fishing on life history parameters of the spiny lobster, Panulirus homarus. The study areas selected had different levels of fishing pressure but relatively similar habitats. The lowest fishing effort was found in Hadbin while the highest fishing effort was...

Creator:: Buktenica, Mark W.
Abstract:: Crater Lake, originally barren of fish, was stocked on an irregular basis from 1888 through 1941 with several species of salmonids. Two species occur in the lake today--kokanee salmon (Oncorhynchus nerka) and rainbow trout (Salmo gairdneri). This study was initiated in the summer of 1986 to evaluate the ecology of...

Creator:: Maule, Alec G.
Abstract:: Plasma concentrations of cortisol, a glucocorticoid hormone that is immunosuppressive in mammals, increase during stress and smoltification of salmonids. There was a reduction in the ability of lymphocytes to generate antibody producing cells (APC) in vivo concurrent with increased plasma cortisol titers during smoltification of coho salmon (Oncorhvnchus kisutch). Cortisol...

Creator:: Mesa, Matthew G.
Abstract:: We examined the behavioral and physiological responses of wild and hatchery-reared cutthroat trout Oncorhynchus clarki subjected to a single electroshock, electroshock plus marking, and multiple electroshocking in natural and artificial streams. In a natural stream, trout released after capture by electrofishing and marking showed distinct behavioral changes: fish immediately sought...
