| dc.description.abstract | 이번 연구에 사용된 멸치는 남해 통영 연안에서 정치망과 권현망을 이용하여 채집되었다. 가랑이 체장범위는 1.9~14.7 cm로 나타났다. 멸치의 주 먹이생물은 50.4%의 상대중요도지수비를 나타낸 요각류였다. 요각류 다음으로 중요한 먹이생물은 47.3%의 상대중요도지수비를 나타낸 난바다곤쟁이류였다. 멸치의 섭식전략을 도해적 방법으로 나타낸 결과, 멸치는 섭식특화종으로 나타났다. 멸치의 성장별 먹이생물 조성 변화를 알아본 결과 (<8.0 cm, 8.0~10.0 cm, 10.0~12.0 cm, ≥12.0 cm) 성장함에 따라 난바다곤쟁이류의 중요도는 증가하고, 요각류의 중요도는 감소하였다. 멸치의 계절별 먹이생물 조성 변화를 알아본 결과, 춘계, 추계, 동계에는 요각류가 우점한 먹이생물이었으며, 하계에는 난바다곤쟁이류가 우점한 먹이생물이었다. | - |
| dc.description.abstract | The diet composition of Engraulis japonicus were studied using 1,087 specimens collected by set net fisheries and boat seine fisheries in the coastal waters of Tongyeong, Korea. The size of the specimens ranged from 1.9 to 14.7 cm in fork length. E. japonicus was fed mainly on Copepods, which constituted 50.4% of IRI, followed by Euphausiids, which constituted 47.3% of IRI. Graphical analysis of the diet composition showed that E. japonicus was specialist predator. Theresult of analysis in ontogenetic changes significantly exhibited among size classes (<8.0 cm, 8.0~10.0 cm, 10.0~12.0 cm, ≥12.0 cm). The proportion of Euphausiids increased, as body size of E. japonicus increased whereas the consumption of Copepods decreased. In the Spring, Autumn and Winter, the diet was dominated by Copepods. In the Summer, the diet was dominated by Euphausiids. | - |
