Protein synthesis in different tissues of mature rainbow trout (Salmo gairdneri r.). influence of triploidy

Cadmium accumulation and protein binding patterns in tissues of the rainbow trout, Salmo gairdneri.

Rainbow trout were exposed to defined levels of cadmium in their aquarium water for differing periods at a variety of near-lethal concentrations that ensured the survival of the majority of the fish. The gills, liver and kidney together accounted for 99% of the accumulated load of body cadmium in the fish under these conditions. Although the proportion of total cadmium present in the liver rema...

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...

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

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...

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).
