속성장을 위한 선발 1세대 전복 (Selected abalone : SA)의 성장률을 조사하기 위하여 동일 사육 환경 조건에서 대조구전복 (control abalone : CA) 과 비교실험을 하였다. 그 결과각 성장형질 (각장, 각폭 및 중량) 은 SA구가 CA구보다 유의하게 빠른 것으로 나타났다. 45일째 및 90일째의 평균 각장에있어 SA구가 CA구 보다 각각 31.7% 및 17.8% 빠르게 나타났으며, 중량에 있어서도 각각 43.7% 및 25.6% 빠른 것으로나타났다. 더욱이 90일째의 각장과 중량의 상대성장 비교에있어서도 SA구가 CA구 보다 유의적으로 높은 상관관계를 나타내었다. 이러한 결과는 선발육종기술을 이용하여 양식전복의 성장률을 증대할 수 있는 가능성을 시사하고 있다.
The growth rates of offspring (SA) of selected abalone, Haliotis discus hannai, population for rapid growth were compared to those of offsping (CA) of the control abalone at bred under the same condition. The growth traits (shell length, shell breadth and total weight) of SA were significantly faster than those of CA at this experiment. At the 45th day and 90th day, the growth rates in shell length of SA were estimated 31.7% and 17.8% faster than those of CA, total weight of SA were estimated 43.7% and 25.6%, respectively. Moreover, the relative growth rate between shell length and total weight of SA showed significant differences higher than one in CA at 90th day. The results suggest a possibility of improving the growth rate of cultured abalone using selection techniques.
