초록
이전의 연구에서 참가리비(Patinopecten yessoensis)인공종묘생산 중 수질관리를 위해 주기적으로 실시하는 환수(전량환수)가 scuticociliates 감염을 촉진 할수 있다는 가능성을 제기하였다. 본 연구에서는 수질과 scuticociliates 감염을 고려한 최적 환수 횟수를결정하고자 하였으며, 유생성장, 생존, scuticociliates 발생을 1차 기준으로 하였으며, 부가하여 중간 육성장으로 이동하여 성장 및 기형 발생율을 2차기준으로 조사하였다. 5일 간격의 환수(3T)가 가장 좋은 결과를 보였다. 잦은 환수(5T)는 수질 개선에도 불구하고 성장 둔화가 확인되었으며, 이것은 scuticociliates 의 감염과 연관이 있는 것으로 보였다. 9일간격의환수(1T) 역시 성장둔화를 보였으며, 5T 실험구와더불어 중간육성이후 성장 둔화(통계적 유의성 없음)와 비정상 발생을 유발하였다. 본 연구결과 최적 환수간격은 5-7일 사이로 나타났다.
Abstract
Our previous finding summarizing that larval sieving process is inevitable but triggers the outbreak of scutica-like ciliates (SLCs) in the seed production of Patinopecten yessoensis urged further study to determine best suggestable sieving interval in an agreeable range of water quality. In the mass seed production of the scallop, SLC outbreak was closely related to the larval sieving in which larvae were drained on the basis of every 3-day (5T), 5-day (3T), 7-day (2T), or 9-day (1T) from culture tanks onto a mesh screen and placed back into new water in cleaned tanks. The larval performance of growth and survival was clearly dependent on the sieving intervals. It was in order of 3T, 5T, 2T, and 1T for both of growth and survival and in reverse order for SLC infection frequency, confirming that larval sieving is necessary but damageable if it overwhelms the larval resistance. Interestingly, the larval damages by the sieving persisted to their ensuing spat life in terms of nursery growth, survival, and abnormality.
