Abstract

Survival with various conditions (water temperature, salinity and air exposure) and sand immersion ability for release of surf clam, Spisula sachalinensis spats, which were artificially seed produced, were investigated. Survival with water temperature conditions of spats showed no difference within the range of 4∼28 $^{\circ}C$ for 10 days. In salinity conditions, survival (%) of spats showed more than 50% in over 22 psu. In air exposure conditions, survival (%) of spats air exposed for 12 hours was no difference within below 2$0^{\circ}C$, however, that of spats air exposed for 16 hours showed below 50% at $25^{\circ}C$. In sand immersion ability, the immersion time was increased with the increase of shell length, and the immersion rate was decreased. Spats of below 15 mm in shell length were emersed more than 90% within 10 min. There was no difference in the immersion time and the immersion rate with the grain sizes of the sand bottom.

이 연구에서는 인공종묘 생산된 북방대합 치패를 대상으로 수온, 염분 및 공기 중 노출에 따른 생존율과 방류를 위한 잠사 능력을 조사하였다. 수온 4∼28$^{\circ}C$ 범위에서 10일간 치패의 수온에 따른 생존율은 차이가 없었으며 ,염분 22 psu 이상에서는 50% 이상의 생존율을 보였다. 또한 기온 2$0^{\circ}C$이하의 공기 중 노출에서 12시간 이내에는 생존율에 차이가 없었으나 $25^{\circ}C$에서는 16시간 이상에서 50% 이하의 생존율을 보였다 각 장에 따른 잠사능력은 각 장이 증가할수록 잠입시간은 길어지고 잠입률은 감소하였으며, 각장 15mm 이하의 치패는 10분 이내에 90% 이상 잠입하였다. 저질모래 크기에 따른 잠입시간과 잠입률에는 차이가 나타나지 않았다.
