The effect of low dietary manganese intake on rainbow trout (Salmo gairdneri).
1. Rainbow trout (Salmo gairdneri) of mean initial weight 15 g were given either a low-manganese or control diet containing 1.3 and 33 mg Mn/kg dry diet respectively. 2. Weight gains over a 24-week feeding period were the same for both groups of trout. 3. Hepatosomatic index, blood packed cell volume and haemoglobin concentration, plasma protein and the activities of aspartic aminotransferase (...
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 کاملThe effect of dietary lysine levels on growth and metabolism of rainbow trout (Salmo gairdneri).
Groups of rainbow trout (Salmo gairdneri; mean weight 5 g) were given diets containing 10, 12, 14, 17, 21, 24 and 26 g lysine/kg diet for 12 weeks. By analysis of the growth values the dietary requirement of lysine in this experiment was found to be 19 g/kg diet. A similar requirement value was obtained from a dose-response curve of expired 14CO2 (following an intraperitoneal injection of L-[U-...
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 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...
