초록

본 연구는 여름철 동해 남부 연안에 출현하는 청어 유어 301개체의 일섭식율 변동을 조사하였다. 어류 시료는 여름철에 3시간 간격으로 24시간 동안 소형 저인망을 이용하여 채집하였다. 청어 유어의 공위율(ratio of empty stomach), 만복도(stomach fullness), 위내용물중량지수(stomach contents index, SCI), 만복도지수(stomach fullness index, IF)는 낮과 밤의 변화에 따라 뚜렷하게 변동하였다. 공위율은 밤에 높았지만, 다른 지수들은 낮에 높아지는 경향을 보였고, 일몰 직전에 가장 높은 값을 보였다. 낮 동안 청어 유어의 위내용물은 요각류(Copepoda)와 난바다곤쟁이류(Euphausiacea)로 구성되어 있었고, 자정 근처에는 거의 소화되어 확인이 어려운 먹이생물로 구성되어 있었다.

Diel changes in feeding activity of juvenile Pacific herring, Clupea pallasii were investigated throughout the analysis of stomach contents of 301 fishes collected from the southeastern coast of Korea. Fish samples were collected every 3 hour over a 24 h period in summer using small bottom trawl. The ratio of empty stomach, stomach fullness, stomach contents index (SCI) and stomach fullness index (IF) of juvenile C. pallasii were varied markedly with day/night changes. The ratio of empty stomach tended be higher during nighttime, while the other values were higher at daytime, with showing peak before sunset. During daytime, the stomach contents mainly were made up of copepods and euphausiids, while the diets at midnight were composed of nearly digested and unidentifiable items.
