Pituitary activation by bacterial endotoxins in rainbow trout (Salmo gairdneri).

Studies on the glomerular filtration rate of rainbow trout (Salmo gairdneri).

The rainbow trout (Salmo gairdneri) and its anadromous form, the steelhead trout, maintain their milieu intbrieur hypotonic to the environment after transfer to sea water (Houston, 1959, i960). Such a transfer involves the physiological adjustment from a condition of continual hydration and electrolyte depletion to the opposite circumstance of a sustained tendency towards dehydration and excess...

Testicular feed back on the hypothalamo - pituitary axis in rainbow trout ( Salmo gairdneri R . )

A testicular feed back on the hypothalamo-pituitary system was studied in male rainbow trout (Salmo gairdneri) after bilateral castration and steroid or testicular supplementation. Experiments were carried out at various periods of the spermatogenetic cycle ; in March-April (resting stage), June (initiation of spermatogenesis), October (end of spermatogenesis and before spermiation), and Decemb...

The effect of hypoxia and anaemia on the swimming performaance of rainbow trout (Salmo gairdneri).

Acid-base Regulation following Exhaustive Exercise: a Comparison between Freshwater- and Sea Water-adapted Rainbow Trout (salmo Gairdneri)

Blood acid-base regulation following exhaustive exercise was investigated in freshwater(FW) and seawater(SW) adapted rainbow trout (Salmo gairdneri) of the same genetic stock. Following exhaustive exercise at 10°C, both FW and SW trout displayed a mixed respiratory and metabolic blood acidosis. However, in FW trout the acidosis was about double that of SW trout and arterial blood pH took twice ...
