1 The Body Compartments and the Distribution of Electrolytes
TLDR
The chapter provides an overview of intracellular compartment and extracellular compartment, and discusses methods for the determination of body compartments, along with reviewing compartmental spaces in fish and electrolyte composition. Expand
Primary and Secondary Effects of Stress in Fish: Some New Data with a General Review
TLDR
Handling in fish induces perturbations of various biological parameters which have been investigated or reviewed in an attempt to analyse and quantify the resulting stress, and all types of stress result in an increase in circulating catecholamines, mainly adrenaline. Expand
Stress induced elevation of plasma cortisol in adult female coho salmon (Oncorhynchus kisutch), is reflected in egg cortisol content, but does not appear to affect early development
TLDR
Cortisol was seen to clear rapidly from eggs in both experimental and control groups soon after fertilization, and there was no significant difference observed between groups by 8 dpf, suggesting that maternal cortisol clears from developing embryonic salmon by the late eyed stage and may not be a factor in later development.

Production of germline transgenic Pacific salmonids with dramatically increased growth performance
TLDR
Transgenic Pacific salmon produced by microinjection of a DNA construct consisting of chinook salmon growth hormone sequences driven by an ocean pout antifreeze protein promoter experienced dramatic enhancement of growth relative to controls. Expand
5 Hormonal Sex Control and its Application to Fish Culture
TLDR
The chapter examines the various components of hormonal sex control studies with particular reference to those factors that influence treatment success, and it is notable that the majority of studies onormonal sex control have involved gonochorist species. Expand
Manipulation of reproduction in farmed fish
TLDR
Sex control technologies have seen rapid development and application in salmonids and tilapias, as a means of increasing both production efficiency and reproductive containment, and will be applied in the near future to other farmed species including flatfish and seabass. Expand
9 - Hormonal Enhancement of Growth
TLDR
It is clear from the range of donor and recipient response relationships shown in the chapter that the growth hormone of teleosts is distinct from that of other vertebrates including the other classes of fish. Expand
Brief treatment with an aromatase inhibitor during sex differentiation causes chromosomally female salmon to develop as normal, functional males
TLDR
Treatment with a nonsteroidal inhibitor of aromatase, the enzyme that catalyzes the conversion from androgens to estrogens, for only 2 hours when the gonads were bipotent, caused genetic females to develop into normal males, providing strong support for Yamamoto's theory that androgens and estrogens are natural sex inducers in gonochoristic fish.
