方斑东风螺水泥池养殖不同底质的生长与存活试验

为了解方斑东风螺水泥池养殖适宜的底质,水泥池底铺设不同底质进行对比试验。结果表明：在池底铺沙情况下,添加10%海泥或添加1%的贝壳,不影响方斑东风螺的正常生长与存活,体重、壳高生长速度分别是23.7～25.1mg/d和105.3～110.4μm/d,不同池生长、存活无明显差异;底沙添加海泥达到30%时,初期东风螺的生长受到不良影响,但随着换水次数的增加,逐渐趋于正常;池底不铺沙时体重生长速度为10.0mg/d,仅为其他池的39.8～42.2%,存活率仅为其他池的65.1～67.6%。认为东风螺水泥池养殖必须铺沙,底沙可适当含泥,含泥量不高于10%。

Tested on the growth and survival of Babylonia areolata culturing in cement pond different substrate

To understand that the B.aerolata culturing in the cement pool suitable bottom substrate,the laying different substrate on the concrete bottom to comparative tests.The results showed ： that the situation in the bottom sanded,when it was added 10% of sea mud and added 1% shell,it can not affect the normal growth and survival of B.aerolata,the growth rates of body weight and shell height of B.aerolata were 23.7 ～ 25.1 mg/day and 105.3 ～ 110.4μm/day,no significant difference in survival and the growth different pools;When the bottom of sand add up to 30% of sea mud,the growth of B.aerolata were adversely affected initial,but it became normal gradually with the increase in the number changing the water;When the bottom did not sanded,the weight rate of B.aerolata is 10.0mg / d,that is only the 39.8 ～ 42.2% of other pools,and it＇s survival rate is only 65.1 ～ 67.6% of that.This paper argues that： the B.aerolata culturing in the cement pool must be sanded on bottom.The bottom substrate may be appropriate added sea mud,but the mud is not higher than 10%.
