The effects of night-lights on feeding by the black rockfish Sebastes inermis in the cage of the Tongyeong marine ranching area were investigated by analyzing the stomach contents of 200 individuals from July 2004 to August 2004. In night-lights groups, black rockfish consumed mainly copepoda, amphipoda and polychaeta; also those in control area fed on copepods, amphipods and polychaets. Copepods (57%) and amphipods (32%) were the major prey organisms for all study period in night-lights. While, major prey items in control area were copepods (88%). Growth of the black rockfish reared in night-lights conditions were significantly higher than that of those in control area. |
