Abstract
To investigate the food organisms and feeding selectivity of slimy (Leiognathus nuchalis) during the postlarval stage, the gut contents of the fish, captured in Kwangrang Bay in 1995, were observed. The food organisms in the gut were composed of copepod egg and nauplius, Tintinnopsis spp. and Codonellopsis sp. The indices of relative importance (IRI) indicated that Tintinnopsis spp. was the most dominant food item (
주둥치 후기자어의 먹이생물과 선택성을 조사하기 위하여 1995년 여름 광양만에서 채집된 주둥치 후기자어의 장내용물을 조사하였다. 주둥치 후기자어의 장에서 관찰된 먹이생물의 종류는 요각류의 난과 nauplius 유생, 유종섬모충류의 Codonellopsis sp.와 Tintinnopsis spp. 등이었다. 상대중요성지수에 의하면 Tintinnopsis spp.가 주 둥치 후기자어의 가장 중요한 먹이생물이었으며 (
