Dietary Iron Requirement of Goldfish (Carassius auratus) Fry
To estimate the dietary iron requirement of common goldfish, Carassius auratus (Linnaeus, 1758), eight isoproteinous diets containing graded levels of dietary iron (FeSO4.7H2O) ranging 34.27-537.14 mg/kg were fed to triplicate groups of C. auratus fry in glass tanks. The rearing medium was groundwater passed through a reverse osmosis water treatment unit. Fish were fed 3% of their body weight p...
متن کاملLatent inhibition experiments with goldfish (Carassius auratus).
Evidence of latent inhibition was sought in a series of experiments with goldfish. In Experiment 1, goldfish were given nonreinforced preexposure to a color that subsequently predicted shock in an activity conditioning situation; their performance did not differ from that of control animals preexposed to a markedly different color. In Experiment 2, a group of goldfish given nonreinforced preexp...
متن کاملIsolation of Shewanella putrefaciens from Goldfish (Carassius auratus auratus)

متن کاملAcoustic stimulation of the ear of the goldfish (Carassius auratus).
Microphonic potentials were recorded from the ears of the goldfish during acoustic stimulation in a situation where sound pressure and particle displacement could be varied. Microphonic potentials from fishes with the swim bladder intact were proportional to sound pressure. After removal of the swim bladder, sound pressure sensitivity declined by 20-35 dB and the response was generated in propo...
