Abstract

Comparisons of growth and survival rate in different culture systems for juvenile abalone were determined in the West Coast of South Korea from June, 2000 to April, 2001. Daily growth rate reached at the maximum by $148.6{\pm}48.96\;{\mu}m/day$ with a stagnant system and at the minimum by $95.3{\pm}21.45\;{\mu}m/day$ with a sprinkler culture system. Survival rate of the juvenile abalone was significantly higher than that in sprinkler culture with a rotary culture (P<0.05). The highest survival rate was 50.0% in the rotary culture and 38.3% was observed in the stagnant culture system. The results from this study indicate that effective survival and growth rate could be predicted in the rotary culture system.

서해안에서 사육시스템 종류에 따른 참전복 치패의 성장과 생존율을 구명하기 위해서 2001년 6월부터 8월까지 연구하였다. 참전복 치패의 일간 성장률은 정체식 수조에서 $148.6{\pm}48.96\;{\mu}m$로 가장 높게 나타났으며, 살수식 수조에서 $95.3{\pm}21.45\;{\mu}$로 가장 낮게 나타났다. 생존율은 살수식 수조보다 회전식 수조에서 높게 나타나 유의한 차이를 나타냈으며(P<0.05), 회전식 수조에서는 50.0%의 높은 생존율을 보인 반면, 정체식 수조에서 38.3%로 가장 낮았다. 본 연구결과는 회전식 수조에서 치패의 성장과 생존율이 가장 높게 나타났다.
