摘要
首次研究了魁蚶亲贝性腺室内控温促熟技术。３月中旬亲贝入池，人工控温，强化饲育２５～２８天，４月中下旬性腺成熟，排放精卵，比自然界提前３个月左右。水温１６℃以上是魁蚶亲贝性腺成熟的迅速期。１９９１年１１月专家鉴定认为，本研究属国内首次，居国内先进水平。
It was the first time to have researched the mature conditions for promoting maturity of thesexual gland of the ark shell by controlling water temperature. In the middle ten days of March, theparent ark shells were released into the pond which water temperature was controlled. After 25～ 28days' intensive cultivation,their sexual glands developed to maturity,and the parent ark shells began to spawn eggs and ejaculate sperms, 3 months earlier than the adult ark shells in the natural waters. The sexual gland developed fastest at the water temperature above 16℃. The result,appraised byexperts concerned in Nov. 1991,met the advarced level at home.
