Abstract

Stomach contents of Hexagrammos otakii collected from mid-western coast of Korea were analysed to determine dietary composition, and ontogenetic and temporal dietary variations. Fish total length (TL) ranged between 5.6 and 32.4 cm. H. otakii primarily consumed amphipods, carid shrimps and teleosts, but also ate various benthic crustaceans and other invertebrates with small amounts. Carid shrimps and teleosts dominated the diet of both immature and mature fishes. Amphipods and polychaetes were secondary, and the former more frequently consumed by smaller specimens, while the latter was more abundant in the diets of larger fishes. DISTLM (distance-based linear modelling) showed diet composition of H. otakii varying significantly with TL, season and water temperature, but did not with maturity.

본 연구는 서해 중부 연안에 출현하는 쥐노래미 (Hexagrammos otakii)의 위내용물 분석을 통하여, 위내용물 조성과 성장 및 계절별 식성변화를 분석하였다. 쥐노래미의 전장 (total length, TL)은 5.6 cm에서 32.4 cm의 범위였다. 쥐노래미는 단각류 (amphipods), 새우류 (carid shrimps), 어류 (teleosts)를 주로 섭식하였고, 그 외 다양한 저서 갑각류와 무척추동물을 소량 섭식하였다. 새우류와 어류는 미성어 (immature)와 성어 (mature)의 위내용물에서 공통적으로 우점하였다. 단각류와 갯지렁이류 (polychaetes)는 그 다음으로 우점하였는데, 단각류는 작은 크기의 어류에서, 갯지렁이류는 큰 크기의 어류에서 그 비율이 더 높았다. DISTLM (distance-based linear modelling) 결과, 쥐노래미의 위내용물은 전장, 계절, 수온에 따라 유의하게 변하였지만, 성숙도와는 관련이 없었다.
