초록

사육 염분의 급성교환 실험에서, 해수의 담수화가 1시간 이내에 이루어졌을 경우 농어, 유어들은 다소의 스트레스 반응과 이온의 변화가 있었으며. 24시간 뒤에도 정상 회복이 더딘 것으로 나타났다. 그러나 5시간에 걸친 담수화 과정 중에 스트레스 반응은 담수화 직후 높게 나타났지만, 24시간 후 빠르게 정상으로 회복되는 것을 알 수 있다. 장기간 염분별 사육실험 결과, 20 ppt가 가장 높은 사료섭식량을 나타내었고, 2 ppt구가 가장 낮았다. 사료효율 또한 2 ppt구이 가장 낮게 나타났고, 10 ppt구가 가장 높았으며, 실험구별 유어의 성장은 실험 종료시 10, 20 및 30 ppt구가 2 ppt보다 유의하게 높은 길이 성장을 보였다. 무게 성장은 실험 종료시 20 ppt가 가장 빠른 무게 성장을 나타내었고, 다음으로 30 ppt, 10 ppt. 2 ppt순으로 나타났다. 염분별 사육유어의 혈액 성상은 2 ppt~30 ppt 사육수에 있어 농어 유어들의 혈액 조성은 큰 차이가 없는 것으로 나타났다.

Two experiments were conducted for the physiological and growth responses of yearling sea bass, Lateolabrax japonicus (total length 24.4$\pm$1.5 cm, body weight 125.4$\pm$25.4 g) by the manipulation of salinity. To study the physiological responses of the sea bass by acute salinity change, we changed water salinity from 30 ppt into 2 ppt in rearing tank through 1 hour or 6 hour. To access the effect of salinity in the growth of sea bass, we also examined the growth of the sea bass in 2, 10, 20 and 30 ppt for 180 days. After salinity change, all yearlings appeared some stress response and ions changes in blood. The yearlings showed a slow recovery by an acute salinity exchange, but a fast recovery by slow salinity exchange. In the study about the influence of salinity in growth, although the food intake of yearlings in 20 ppt was significantly higher than the yearling in the other salinities, feed efficiency was higher in 10 ppt than the other salinities. However, the food intake and the feed efficiency in 2 ppt were significantly lower than in other groups. The growth of yearlings was significantly faster in 20 ppt than in the other salinities, but the growth showed significantly slower in 2 ppt than in the other salinities.
