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...
متن کاملThe effect of dietary composition and of insulin on gluconeogenesis in rainbow trout (Salmo gairdneri).
1. The activities at 15" of three gluconeogenic enzymes, D-fructose-l,6-diphosphate, 1-phosphohydrolase (EC 3.1.3.1 l), pyruvate carboxylase (EC 6.4.1.1) and phosphoenolpyruvate carboxykinase (4.1.1.32), were determined in liver, kidney, gill and muscle of rainbow trout (Sulmo guirdneri) given a commercial diet. The results indicated that liver and kidney are the main sites of gluconeogenesis. ...
متن کاملToxicokinetics 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...
متن کاملThe Effect of Osmotic and Ion-osmotic Stresses on the Mortality of Rainbow Trout (salmo Gairdneri)
I. The possibility that costs of Ionic and osmotic regulation are different in fish was assessed using mortality rates of rainbow trout exposed to an ionically active substance, sodium chloride and a non-electrolyte. mannitol, in the ambient water. 2. A 24.hr LC,, of 175 mOsm was calculated from data for fish exposed to sodium chloride concns of 400.450. 500. 550. 600,650 and 700 mOsm. 3. Simil...
متن کاملThe effect of increased metabolic rate on renal function in the rainbow trout, Salmo Gairdneri.
1. A highly significant linear correlation was found between glomerular filtration rate and urine flow rate in both freshwater and seawater trout. The percentage tubular reabsorption of water was approximately 33% greater in seawater trout than in freshwater trout. 2. As oxygen consumption increased, the urine flow rate increased in freshwater and seawater rainbow trout. The proportional increa...
