초록

수온은 양식 대상어의 종자생산에 영향을 미치는 중요한 환경 요인이다. 본 연구는 최근 급격한 자원 감소를 보이고 있는 한해성 어종인 명태의 안정적인 종자생산을 위한 기초자료로 활용하기 위해 수온이 명태의 부화 및 초기 자어 성장에 미치는 영향을 조사하였다. 수정란의 생존율은 5℃가 8℃와 11℃에 비하여 높게 나타났으며, 부화율은 8℃에서 가장 우수하게 나타났다. 그러나 첫 부화, 50% 부화 및 완전 부화까지의 소요 시간은 11℃가 5℃와 8℃에 비하여 빠르게 나타났다. 12주간의 사육기간 동안 자어의 생존율은 5℃가 8℃와 11℃에 비하여 높게 나타났으나, 성장은 11℃가 5℃와 8℃에 비하여 높게 나타났다.

This study aimed to investigate the effects of different water temperature (5, 8 and 11℃) on egg hatch and larval growth of walleye pollock Gadus chalcogrammus to improve rearing techniques for this species. Survival of eggs maintained at 5℃ was higher than that of eggs maintained at 8℃ and 11℃. The greatest hatching rate was obtained for larvae maintained at 8℃. However, time to first, 50% and 100% hatch of eggs maintained at 11℃ was shorter than at 5℃ and 8℃. A higher survival was observed in larvae reared at 5℃ compared to 8℃ and 11℃ and the greatest growth was observed in larvae reared at 11℃ compared to 5℃ and 8℃ during the feeding trial. This study demonstrated the importance of water temperature, as it affects culture performance of eggs and larval pollock. The results from this study provides valuable information for further development of pollock aquaculture.
