본 연구는 전복 먹이종류에 따른 성장 효율성 검토를 위하여같은 어미에서 생산된 같은 크기의 개체를 사용하여, 동일한사육환경 내에서 천연먹이인 미역(UP), 다시마(LJ) 및 시판용전복 배합사료(FD) 를 공급하였다. 그 결과, 각장형질의 성장은 미역(UP) 및 다시마(LJ) 를 공급한 실험구가 배합사료(FD) 실험구 보다 유의적으로 빠른 것으로 나타났다. 반면, 증체율은 해조류를 공급한 실험구(UP 및 LJ) 보다 배합사료(FD) 실험구가 높게 나타났다. 이러한 결과는 먹이의 종류에따라 패각의 성장과 근육부위의 성장이 각각 다르게 나타날 수있다고 생각된다.
The effect of three different diets (formulated diet, FD; Undaria pinnatifida, UP; Laminaria japonica, LJ) on growth in the Haliotis discus hannai for 90 days was investigated. The shell length of UP (80.62 ± 1.92 mm) and LJ (81.14 ± 1.16 mm) were significantly faster than those of FD (79.38 ± 1.69 mm) (P < 0.05). However, shell breadth and total weight were no significant difference among three diets. On the other hand, the weight gain of FD (16.65% for 0-45day and 25.71% for 45-90day) tend to have higher than those of UP (14.57% and 23.30%) and LJ (12.65% and 24.51%). This results shows that seaweed diets (UP and LJ) help the shell growth of abalone and formulated diet (FD) help the weight gain of abalone. Therefore, the growth of shell and muscle will depend on different diets.
