Effects of o,p'-DDE on the immune system of juvenile chinook salmon (Oncorhynchus tshawytscha)

Creator:: Milston, Ruth Helen
Abstract:: Environmental factors such as chemical contamination can have immunomodulatory effects on the immune response of fish and may be contributing to the decline in salmonid populations by augmenting disease susceptibility. Xenobiotics can interfere with the immune system at several levels of complexity, and different immune cells and processes have variable...

Sex determination in Nile tilapia, Oreochromis niloticus: gene expression, masculinization methods, and environmental effects

Creator:: Sánchez, Wilfrido M. Contreras
Abstract:: Sex differentiation in fish is a labile process that allows sex inversion in several species. The inherent capacity of fish germ cells to differentiate into oocytes or spermatocytes constitutes a key factor allowing for functional sex inversion. This thesis set out to determine the mechanism involved in steroid-induced sex differentiation...

Sex steroid profiles of coho salmon, Oncorhynchus Kisutch, during early development and sexual differentiation

Creator:: Feist, Grant
Abstract:: Whole body sex steroid levels of coho salmon, Oncorhynchus kisutch, were measured via radioimmunoassay during early development and sexual differentiation. Steroid profiles of testosterone (T), 11-ketotestosterone (KT) , androstenedione (A), progesterone (P4) , 17β, -hydroxy- 20β -dihydroprogesterone (DHP) , and 17β -estradiol (E2) were generated beginning with unfertilized eggs and...

Immune responses of juvenile chinook salmon (Oncorhynchus tshawytscha) to p,p-̓DDE and tributyltin

Creator:: Misumi, Ichiro
Abstract:: In this thesis, we examined the effects of the exposures to anthropogenic pollutants on the fish, primarily juvenile chinook salmon, immune system using newly and recently developed immune assays. In addition, we developed a new assay for measuring immunocompetence of fish. In the first chapter, the Alamar Blue assay was...

Endocrine regulation of final oocyte maturation and sex differentiation in salmonids

Creator:: Fitzpatrick, Martin S.
Abstract:: Sexual maturation and sex differentiation comprise facets of a common theme: reproduction. The endocrine system regulates many of the critical physiological processes necessary for reproduction and offers a framework within which technologies can be developed for controlling sexual maturation and sex differentiation. The studies described in this thesis were undertaken...
