【摘要】 本文报道了1991年4月25日～6月15日,利用对虾育苗室,采用人工升温和自然升温(当地水温回升较早),对太平洋牡蛎(Crossostrea gigas)亲见人工促熟的结果,使产卵期提前15～30天。产卵积温平均为668℃。同时对不同海域的亲贝外部形态及性腺发育、产卵情况作了比较。更多还原

【Abstract】 Artificial promoting maturity of Pacific oyster (Crassostrea gigas)parents were performed, in the laboratory for Chinese prawn spat rearing, by the seawater temperature rising resulted by heating artificially and warming-up naturally(the latter is much rapid in this area) during the period from April 25th to June15th, 1991. The results show that the spawn period was carried out 15-30 days inadvance. The accumulated temperature was 668℃ in average. The outer morphology,gonad development and the spawning features in different areas were compared.更多还原
