菲律宾蛤仔室内工厂化育苗试验

Experiment on the Industrial Seed Rearing of Ruditapes philippinarum

2005年5月在青岛红岛蛤原良种开发有限公司进行了室内自动控温条件下菲律宾蛤仔(Ruditapes philippinarum) 育苗试验,对试验结果进行了分析,并探讨了影响其性腺发育的因素和死亡高峰期的形成原因、对策。除此之外,还对菲律宾蛤仔浮游期和附着期的生长速率进行了比较,并对浮游期不同培育密度对生长、成活率的影响进行了初步研究。利用室内工厂化育苗技术,可以充分发挥高密度生产的优势,通过对苗种培育过程中水质、饵料和环境条件的全面控制,消除或减少敌害生物的影响,提高幼体的抗逆能力,从而杜绝抗生素的使用；在降低育苗生产环境污染的同时,向养殖户提供健康、优质的贝类苗种,是一种与环境相协调的、可持续的水产苗种培育模式。

The experiment was carried out under indoor automatic temperature control system during May 2005.The factors that influenced the development of gonad,the causes that induced the peak of death rate and the countermeasures were proposed.Moreover,the growth rate during pelagic period and attaching period was compared and the influence of density to the growth and survival rate of the pelagic larva was also studied.
