摘要
以凡纳滨对虾(Litopenaeus vannamei)成虾为研究对象,设计了4个盐度梯度和4个温度梯度,采用正交试验,研究了温度、盐度及其交互作用对凡纳滨对虾耗氧率和氨氮、磷排泄率的影响。凡纳滨对虾在温度和盐度交互作用下耗氧率为0.266~0.582mg/(g.h),平均为0.419mg/(g.h);磷排泄率为0.935~2.279μg/(g.h),平均为1.532μg/(g.h);氨氮排泄率为1.222~2.656μg/(g.h),平均为1.854μg/(g.h)。统计分析显示,温度和盐度对耗氧率和氨氮、磷排泄率都有极为显著的影响(P<0.01),且两者之间交互作用极其显著(P<0.01)。
Taking white pacific adult shrimp (Litopenaeus vannamei) as the research object, the orthogonal experiment between 4 salinity levels and g water temperature levels is designed in this paper. The interaction effect of water temperature and salinity on oxygen consumption rates, ammonia-nitrogen excretion rates and phosphate excretion rates for white pacific shrimp (Litopenaeus vannamei) were studied. In the interaction effect of above-mentioned factors,the rate of oxygen consumption varied from 0. 266 to 0. 582 mg/(g · h) ,the average value is 0. 419 mg/( g · h). And the rate of phosphorous excretion varied from 0. 935 to 2. 279 μg/( g · h),the average value is 1. 532 μg/(g ·h). Meanwhile the rate of ammonia-nitrogen excretion varied from 1. 222 to 2. 656 μg/( g · h), the average value is 1. 854 μg/( g · h). The statistical analysis showed, the effect of temperature and salinity on oxygen consumption rates, ammonia-nitrogen or phosphate excretion rates for white pacific shrimp (Litopenaeus vannamei) are significant (P 〈 0.01 ), and the interaction effect is remarkable too (P 〈 0.01 ).
