摘要
通过对南美白对虾的不同品系、放养密度、放苗时间以及养殖效益的统计分析发现:同一品系虾苗在不同区域养殖,虾苗的发病时间和养殖效益存在统计学差异;不同品系虾苗在同一区域养殖,虾苗的发病时间和养殖效益没有统计学差异。随着养殖密度的增大,发病虾池所占的比例增加;同时,同一品系的虾苗在不同的时间放苗,病害发生的比例和养殖效益是不同的。
From statistical analysis to different strains,stocking density,larva stocking time and breeding efficiency for Penaeus Vannamei,it was found that there was a statistical difference in incidence time and breeding efficiency when shrimps of the same strain were cultured in different region.If shrimps of different strains were cultured in the same area,there were no statistical difference in the disease onset time and breeding efficiency of the shrimps.With the increase of breeding density,the proportion of diseased shrimp ponds increased.At the same time,the proportion of disease occurrence and breeding benefits were different when the stocking time was different for same strain.
