Purification and characterization of two lysozymes from rainbow trout (Salmo gairdneri)

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...

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...

Nocardial Infection in Hatchery-reared Fingerling Rainbow Trout (salmo Gairdneri).

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

Endotoxins from Escherichia coli and Aeromonas salmonicida caused marked cortisol production in the rainbow trout (Salmo gairdneri).

Biochemical analysis of vitellogenin from rainbow trout (Salmo gairdneri): fatty acid composition of phospholipids.

Vitellogenin was obtained from three year-old vitellogenic trout. Two procedures of isolation were compared: dialysis against distilled water and ultracentrifugation in the density interval 1.21-1.28 g/ml. Similar patterns were observed by gel filtration and electrophoresis for both preparations of vitellogenin, indicating that electric charge and molecular weight were not modified by either pr...
