通过观测莱州湾海湾扇贝8~10月内脏得率及向往得率的变化规律,对海湾扇贝的秋季生殖习性进行探讨,认为:海湾扇贝用秋季半人工育苗法替代室内加温育苗法可获得较好苗种。投放采苗袋20天后,秋苗平均壳高4.96mm。产卵前,内脏得率呈上升趋势,之后下降;肉柱得率一直呈上升趋势。
By observing the variation of visceral rate and entitative rate from August to October in Laizhou Bay Gulf Scallop, we studied the autumn reproductive habits of Gulf scallop. It is concluded that the use of semi-artificial seeding seedling instead of indoor heating and nursery method in Gulf scallop Good seed. After putting seedling bags for 20 days, the average height of autumn seedlings is 4.96mm. Before spawning, the rate of viscera showed an upward trend, then decreased; the rate of meat pillars has been on the rise.
