Abstract

To investigate the feeding habits of Tridentiger trigonocephalus juveniles captured in the intertidal zone of Dodun-ri, Seocheon-gun from the end of May to early June 2012, the gut contents were observed. Feeding incidence of the juveniles increased twice a day, first in the morning and second in the afternoon. The major food organisms of the juveniles (6.5~10.0 mm NL) were composed of copepods (65.4%), amphipods (2.0%), shrimp larvae (14.5%), polychaete larvae (22.6%), and etc. These food items held more than 2 percentage in the dry weight of the total food items.

두줄망둑 자치어기의 먹이생물을 조사하기 위하여 2012년 5월말부터 6월초 사이에 충남 서천군 서면 도둔리의 조간대에서 채집된 두줄망둑의 위내용물을 조사하였다. 섭식참여율은 낮 동안에 오전과 오후에 각각 한 차례씩 증가하는 경향을 보였다. 두줄망둑의 자치어의 주요 먹이생물은 copepods, amphipods, shrimp larvae, polychaete larvae 등이었으며, 이들이 건중량의 2% 이상을 차지하였다. 그중에서 copepods가 평균 65.5%로 가장 많은 양을 차지하였고, polychaete larvae, shrimp larvae 등의 순으로 많이 출현하였다. 먹이생물의 개체수 조성비를 보면, copepods가 65.4%를 차지하여 가장 높았고, polychaete larvae는 22.6%, shrimp larvae는 14.5%를 차지하였다. 먹이생물 중 copepods는 개체수 조성비가 높고 출현율도 높아서, IRI가 5,369.3으로 가장 높은 수치를 나타내었고, polychaete larvae는 653.1, shrimp larvae는 287.1의 수치를 나타내었다. 따라서 두줄망둑의 자치어기의 가장 중요한 먹이생물은 copepods, polychaete larvae, shrimp larvae 등이었다.
