Oxygen deficiency and negative temperature as teratogenic factors in rainbow trout (Salmo gairdneri Rich.)

Respiratory control of arterial pH as temperature changes in rainbow trout Salmo gairdneri.

RANDALL, D. J., AND J. N. CAMERON. Respiratory control of arterial pH as temperature changes in rainbow trout Salmo gairdneri. Am. J. Physiol. 225(4) : 997-1002. 1973.-Arterial blood pH decreased as temperature increased, dpH/dT was 0.017 unit/“C and was independent of the acclimation history of the fish. Ventilation volume increased in proportion to oxygen uptake with temperature. Changes in w...

Lactate and Proton Dynamics in the Rainbow Trout (salmo Gairdneri)

Chronically cannulated rainbow trout were subjected to 6 min of severe burst exercise and monitored over a 12 h recovery period. There were shortlived increases in haematocrit, haemoglobin, plasma protein, Na and Cl~ levels. Plasma [Cl~] later declined below normal as organic anions accumulated. A much larger and more prolonged elevation in plasma [K] probably resulted from intracellular acidos...

Toxicokinetics of Fenvalerate in Rainbow Trout (Salmo Gairdneri)

An in vivo rainbow trout (Salmo gairdneri) preparation was used to evaluate the gill uptake and toxicokinetics of [3H]fenvalerate ([R,S]-α-cyano-3-phenoxybenzyl [R,S]-2-[4-chloro-phenyl]-3-methylbutyrate), a synthetic pyrethroid insecticide. Fish were exposed to technical-grade fenvalerate (0.28 or 23 ng/L) or an emulsifiable-concentrate formulation (16 ng/L) for 36 to 48 h. No significant effe...

Oxygen Consumption and Swimming Performance in Hypoxia-acclimated Rainbow Trout Salmo Gairdneri

1. Swimming performance and oxygen consumption of normoxic (control) and hypoxia-acclimated (P02 — 40mmHg) rainbow trout, Salmo gairdneri Richardson, were monitored at >145, 60 and 40mmHg. 2. Maximum swimming velocity at 40mmHg was reduced from >54-8cms"' to 41-4cms" in controls and to 40-6cms" in hypoxiaacclimated fish. 3. Normoxic oxygen consumption of control fish ranged from Q-T-SmgOzkg-'h(...
