TLDR
A single intraperitoneal T4 injection was found to be impractical owing to rapid T4 turnover, and frequent injections would be required which would probably not eliminate surges in plasma T4 due to intra peritoneal injection.About:

9 - Hormonal Enhancement of Growth
TL;DR: 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.

Chapter 17 Fasting and starvation
Isabel Navarro,Joaquim Gutiérrez +1 more
TL;DR: The chapter presents a brief overview of gross metabolic and enzymatic changes observed in fasting and starving fish and elaborates various parameters of endocrine regulation during fasting and starvation in fishes.
Journal ArticleDOI
Application of thyroid and steroid hormones as anabolic agents in fish culture
TL;DR: This review is directed towards evaluating the role for thyroid hormones and steroids in fish culture, with particular attention given to the following topics: growth, appetite, food conversion, carcass composition, salt water tolerance, species specificity, deleterious responses and economic implications.
Journal ArticleDOI
Effects of thyroxin, cortisol, growth hormone, and prolactin on lipid metabolism of coho salmon, Oncorhynchus kisutch, during smoltification.
TL;DR: The results indicate that T4, cortisol, GH, and PRL all stimulate lipid mobilization in developing salmon by enhancement of lipolysis and suggest that T3, Cortisol,GH, andPRL are among the factors which contribute to smoltification-associated lipid depletion.

Measurement and regulation of thyroidal status in teleost fish
J.G. Eales,S. B. Brown +1 more
TL;DR: The stages in teleost thyroid function and its regulation are reviewed, from the initial biosynthesis of the TH to their eventual interaction with putative receptors, which is highly responsive to physiologic state and environmental variables.

The Thyroid Gland.
TL;DR: The rapid growth of knowledge in recent years concerning the physiology and biochemistry of the thyroid hormones and the pathogenesis and treatment of thyroid diseases has no doubt been responsible for the recent spate of books dealing with these subjects.

4 - Thyroid Function and Its Control in Fishes
TL;DR: This chapter discusses the exhaustive review of thyroidal function in fishes and discusses the four components of thyroid, such as the brain, a complex of nervous afferents to a center, presumably in the hypothalamus, regulates pituitary thyrotropic secretion.
Journal ArticleDOI
The influence of temperature on histological and radiochemical measurements of thyroid activity in the eastern brook trout, Salvelinus fontinalis Mitchell
D. E. Drury,J. G. Eales +1 more
TL;DR: Histological and radiochemical techniques for assessing thyroid activity were compared on yearling brook trout acclimated at 5, 12, and 15 °C to determine the mean thyroid follicle epithelial cell height.

Measurement of circulating thyroxine in several freshwater teleosts by competitive binding analysis
D. A. Higgs,J. G. Eales +1 more
TL;DR: A competitive binding analysis using human thyroxine-binding globulin (TBG) and Sephadex columns was the most satisfactory of several methods tested for measuring fish plasma thyroxines concentrations.
