Cortisol and the immune system of juvenile Pacific salmon during stress and development

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...

Ecological influence of bacterial kidney disease on juvenile spring chinook salmon : effects on predator avoidance ability, smoltification, and physiological responses to stress

Creator:: Mesa, Matthew G.
Abstract:: Juvenile chinook salmon (Oncorhynchus tshawytscha) were experimentally infected with Renibacterium salmoninarum (Rs), the causative agent of bacterial kidney disease (BKD), to investigate the effects of BKD on three aspects of juvenile salmonid performance: (1) predator avoidance ability; (2) smoltification; and (3) physiological responses to stress. For these experiments, fish with...

Abstract:: Periodic determinations of plasma hormone levels suggested that changes in interrenal activity are unrelated to changes in thyroidal or gonadal activity during development (smoltification) of juvenile coho salmon (Oncorhynchus kisutch). Moreover, in an experiment where fish were reared under various conditions of crowding and water inflow rate, it appeared that...

Early development of the endocrine system in salmonids : regulation of sex differentiation and ontogeny of the stress response

Creator:: Floyd, Donald J.
Abstract:: Sex steroids, follicle stimulating hormone (FSH), luteinizing hormone (LH) and gonadotropin releasing hormone (GnRH) were measured in monosex and mixed sex populations of rainbow trout during early development. Steroids declined following fertilization, increased at hatch, then fell and remained constant thereafter. Trends toward differences in steroids between males and females...

Abstract:: A mutational analysis was conducted to investigate the functions of the tobacco etch potyvirus VPgproteinase (NIa) protein in vivo. The NIa N-terminal domain contains the VPg attachment site, whereas the C-terminal domain contains a picornavirus 3C-like proteinase.

Abstract:: Juvenile steelhead are known to associate with shiner groups, though they also compete for food. Steelhead form dominance hierarchies within cohorts and aggressively defend feeding territories against all other fish. This study focused on the differential effect of shiner competition on steelhead of different social standing. Survival of subordinate juvenile...
