摘要
本试验利用一个室外露天水容量为187立方米的水泥池进行马氏珠母贝人工育苗,一次育出贝苗5065万只,平均每立方米水体收贝苗27.08万只。室外大池育苗具有耗饵量少,节约人力,培育的幼虫和贝苗生长快和产苗量大等优点,能够迅速提高贝苗总产量,解决目前存在的贝苗(?)足的困难,值得提倡推广。
In this experiment a large-scale outdoor concrete tank(Water depth 1.7m.,187 cubicmetre capacity)was used to breed the larvae of pearl oyster(Pinctada martensii).Itproduced satisfactory results with a total yield of 50,650,000 spats(average 270,800 spatsper cubic metre).Comparing with in-door little water body,the breeding method of pearl oyster lar-vae in large-scale outdoor thank possess the following advantages:1.The larvae and spats grew well and fast;2.Only a little amount of food-organism supply is needed.3.The labour consumed are less.4.The total amount of the spats yield are very high.The method of breeding pearl oyster larvae in large-scale outdoor concrete tank arerecommended for commercial production.
