“…The cultured fish showed components of a circadian rhythm in their instantaneous OCR. 13 Kadri et al revealed a clear daily feeding rhythm in caged sea-winter salmon during the summer, with peaks in feeding activity in the early morning and evening and a marked depression during the early afternoon. Several behavioral studies have indicated that many fish are entrained to diurnal variation.…”

“…[4][5][6] For example, Fanta et al reported that adult female Notothenia neglecta maintained under a controlled 24 h light regimen (with 8 h of dimness), showed a clear circadian rhythm in their muscular oxygen levels and motility, and low amplitude oxygen consumption and respiratory frequency in response to gradual anoxia. 13 Kadri et al revealed a clear daily feeding rhythm in caged sea-winter salmon during the summer, with peaks in feeding activity in the early morning and evening and a marked depression during the early afternoon. 14 They observed that the feeding pattern was not entrained to food availability; instead, the pattern may have been a direct response to environmental conditions, especially to light and/or temperature.…”

To compare metabolic activity rhythms between wild and cultured black rockfish Sebastes schlegeli, we measured long‐term oxygen consumption rates (OCR) using an automatic intermittent‐flow respirometer under constant temperature and darkness. Oxygen consumption rates peaked among wild black rockfish at 12.4 h intervals, which corresponded to a circatidal rhythm. The wild fish were probably exhibiting responses that corresponded to tidal events in their natural environment. However, when captured wild black rockfish were kept under laboratory conditions (12 h light [L] : 12 h dark [D]) for 30 days, the OCR shifted to a circadian rhythm (24.1–24.9 h). The OCR of cultured black rockfish that had been reared in a tank for 9 months peaked at approximately 24 h intervals, corresponding to a circadian rhythm. The results of this study suggest that the differences in OCR patterns between wild and cultured fish were mainly due to differences in the environmental conditions between tidal and non‐tidal habitats.

Effects of pentachlorophenol (PCP) on the oxygen consumption rate of the river puffer fish Takif ugu o bscurus 'Marine Biotechnology Lab., and 'Chemical Oceanography Division. Korea Ocean Research & Development Institute, Ansan. PO Box 29. Seoul 425-600. Korea ABSTRACT: Laboratory bioassays were conducted to determine the effects of pentachlorophenol (PCP) on the oxygen consumption of the river puffer fish Takifugu ohscnrus. Oxygen consu.mption of 6 to 9 mo old puffer fish was measured with an automatic intermittent-flow-respirometer (AIFR). Oxygen consumption rate was s~gnificantly increased by exposing fish to concentrations of 50, 100, 200 and 500 ppb PCP Follow~ng exposure to 50 or 100 ppb PCP, the instantaneous rate of oxygen consumption was considerably increased. T obscurus exposed to 200 ppb PCP, however, exhibited a breakdown in the biorhythm of oxygen consumption presumably due to a strong physiological stress caused by the higher PCP concentrations. River puffer fish exposed to 500 ppb PCP died in 10 h.
