摘要
进行了塔形马蹄螺(Trochus pyramis Born)的人工促熟及催产实验。结果表明,塔形马蹄螺的生物学最小型为:雄性个体壳高1.33cm,雌性个体壳高1.42cm。塔形马蹄螺人工促熟的适宜温度为26～28℃,用叉珊藻(Jania arborescens Yendo)为饵料促熟塔形马蹄螺的效果较好。经促熟的实验贝采用降温阴干的方法进行催产效果较好,实验贝的催产率最高可达95%左右。
An experiment for artificial promoting maturation and inducing spawning in Trochus pyramis Born was undertaken in the paper. The results show that the biological minimum size of T. pyramis Born is 1.35 cm for males and 1.47 cm for females in shell height, that the optimum temperature for artificial promoting maturation in T. pyramis Born is 26-28℃, that feeding with Jania arborescens Yendo for artificial promoting maturation is more effective, and that the induction effect by drying the artificially matured individuals in shade at a 10℃ lower than the water temperature is better, the discharging gametes proportion of the experimental individuals arrives at as high as 95%.
