서해연안 조간대에 서식하는 왜풀망둑 (Acanthogobius elongata) 자치어의 먹이생물

Abstract

To investigate the feeding habits of Acanthogobius elongata juveniles, the gut contents of the juveniles, captured in the intertidal zone of Dodun-ri, Sochon from the end of May to early June 2018, were observed. Feeding incidence of the juveniles increased twice a day, first in the morning and second in the afternoon. The major food items of the juvenils (7.0〜10.5 ㎜ NL) were copepods, amphipods, shrimp larvae and polychaete larvae. These food items held more than 2 percentage in the dry weight of the total food items.
