부산 주변해역에서 출현하는 살살치(Scorpaena neglecta)의 식성

Abstract

The feeding habits of Scorpaena neglecta were studied based on an examination ofthe stomach contents of 478 specimens collected between January and December 2006 in theCoastal Waters off Busan. The specimens ranged from 9.0 to 23.5cm in Standard length(SL). S. neglec-ta is a piscivore and consumes mainly teleosts such as Acropoma japonicum , Coelorinchus multispi-nulosus , Chaeturichthys stigmatias. Its diet also includes crabs, shrimps, cephalopod and stoma-topod. Smaller individuals (16 cm SL) consume mainly crabs and shrimps. The proportion of theseprey items (crabs and shrimps) decreases with increasing fish size, and this decrease parallels theincreased consumption of fish. The mean prey size sharply increases between 12 and 20 cm SL of S.neglecta size.
