Abstract

This experiment was conducted to evaluate the effects of different substrates in rearing tank on growth and body composition of juvenile sea cucumber Apostichophus japonicus. Sea cucumber (average weight 3.6) were randomly distributed at a density of 10 juvenile per tank into nine tanks providing three different substrates including free-substrates, sand and wave-shaped plastic sheet as (shelter). Juveniles were fed with a commercial feed once in every 2 days for 8 weeks. At the end of the experiment, survival of sea cucumber was not affected by the presence of substrates (P>0.05). Weight gain and specific growth rate of sea cucumber reared in the tanks with sand were significantly higher than those of sea cucumber reared in the tanks with shelter and without substrate (P<0.05). Crude protein and crude lipid of whole body in sea cucumber reared in free-substrate tanks were significantly higher than those of juvenile reared in the tanks with other substrates (P<0.05). Higher ash content was obtained in sea cucumber reared in the tanks with sand compared to that of juvenile reared in the tanks with other substrates (P<0.05). The results of this study suggest that growth and proximate composition of whole body of sea cucumber was significantly affected by substrates. Among materials tested, sand may be a proper substrate for sea cucumber culture.

본 연구는 사육수조 내 shelter와 sand가 어린 해삼의 성장 및 체조성에 미치는 영향을 조사하기 위해 수행되었다. 사육수조에 shelter와 모래를 넣지 않거나(Con), shelter (Shelter)와 모래(Sand)를 각각 넣어 사육 조건을 달리하여 평균체중 3.6 g의 어린 해삼을 3반복으로 수용하여 수입 분말사료(조단백질 16.8%, 조지방 0.3%)를 8주간 공급하였다. 생존율은 80% 이상으로 모든 실험구간에 유의한 차이가 없었다(P>0.05). 증중율과 일간 성장율은 Sand 실험 구에서 가장 높았고, Con 실험 구에서 가장 낮은 값을 보였다(P<0.05). 해삼의 단백질과 지질 함량은 Con 실험구에서 가장 높게 나타났으며, 회분 함량은 Sand 실험구에서 가장 높은 값을 보였다(P<0.05). 이상의 결과로 보아, 사육수조 내 shelter와 모래는 어린 해삼의 성장과 체조성에 영향을 미치며, 모래는 어린 해삼의 적정 성장을 위한 사육수조의 기질로 사용될 수 있을 것으로 판단된다.
