Heart rate conditioning in goldfish (Carassius auratus) and not in 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...

Nocardial Infection in Hatchery-reared Fingerling 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...

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).

Rate of gain of heat-tolerance in goldfish (Carassius auratus).

Experiments were designed to determine the rate of gain of heat-tolerance for three different groups of goldfish, Carassius auratus, respectively acclimated to 4°C., 12°C., and 20°C., and subsequently moved to a temperature S°C. higher. The rate of change of heat-tolerance showed a marked difference in the three greups, twenty or more days being required for complete acclimation in the 40C. gro...
