The effects of environmental stressors on cardiac gene expression and contractility in rainbow trout (Oncorhynchus mykiss)

Creator:

Momoda, Tracey S.

Abstract:

Rainbow trout (Oncorhynchus mykiss) experience a variety of stressors in their natural environment as well as in aquaculture that can have negative effects on their physiology. The effects of physiological stress and endocrine disruption have been well described in fish. However, there is a scarcity of information on the effects...

Influences of environmental acidification on salmonid reproduction

Creator:

Weiner, Gary S.

Abstract:

Reproduction of salmonid fishes in acidic water was studied using the rainbow trout (Salmo gairdneri). Adult trout were exposed to various levels of hydrogen ion (pH levels 4.5, 5.0, 5.5, and control [6.5 to 7.1]) during the final 6 weeks of reproductive maturation. Reduced survival rates of the progeny of...

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...

Gene expression in the liver of rainbow trout, Oncorhynchus mykiss, during the stress response

Creator:

Momoda, Tracey S.

Abstract:

The extent to which responses to stress are maladaptive or adaptive to the long-term survival of fish remains to be better understood. The aim of this study was to identify differentially expressed genes in the livers of rainbow trout, Oncorhynchus mykiss, responding to an experimental stressor. Gene expression responses were...
