Establishment, characterization, and viral susceptibility of two cell lines derived from goldfish Carassius auratus muscle and swim bladder.

The response of the swim bladder of the goldfish (Carassius auratus) to acoustic stimuli.

The Secretion of Inert Gas into the Swim-bladder of Fish

The composition of the gas mixture secreted into the swim-bladders of several species of fish has been determined in the mass spectrometer. The secreted gas differed greatly from the gas mixture breathed by the fish in the relative proportions of the chemically inert gases, argon, neon, helium, and nitrogen. Relative to nitrogen the proportion of the very soluble argon was increased and the pro...

Effects of troxerutin on mRNA expression of the genes encoding lysozyme and tumor necrosis factor-α and histology in goldfish (Carassius auratus) skin

Troxerutin, a derivative of the natural bioflavonoid rutin, has important biological effects, including immunostimulatory activity. This study aimed to evaluate the effects of dietary troxerutin supplement on histology and mRNA expression of the genes encoding lysozyme and tumor necrosis factor-α in goldfish, Carassius auratus skin. Fish fingerlings with mean initial weights of 2.74 ± 0.08 g we...

Acoustic 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...

Effect of Light and Music on Growth Performance and Survival Rate of Goldfish (Carassius auratus)

 Environmental enrichment is one of the methods for improving fish growth performance. In the present trial, the effects of both light color and music on growth performance and survival of goldfish (Carassius auratus) (initial mean weight: 4.15±0.08 g) were investigated for 2 months. Two light color treatments (red light and white light) and three music treatments (M0: without music, M30:30 min...
