摘要
2003年1～6月,对海南琼山、文昌、万宁和三亚地区的51口高位虾池进行了跟踪调查。结果表明:放养密度与养殖周期、产量和饵料系数成正相关,其相关系数分别为:0.897、0.91和0.864。放养密度和饵料系数是影响养殖成本的两个主要因素,其关系可用线性回归方程:S=7.04+0.421X+1.209C来表示。高位池最适放养密度为210～255万尾/hm2。
Pacific white shrimp(Litopenaeus vannamei) culture was examined in 51 shrimp ponds far away from intertidal zones in Qiongshan,Wenchang, Wanning and Sanya in Hainan districts during January to June in 2004. The result indicated that there were the linear correlation among stocking density, rearing period, yield, and feed coefficient with the separate correlative coefficient of 0.897, 0.91 and 0.864. The stocking density and feed coefficient were the major factors affecting the production cost. Their correlation may express as the equation : S=7.04+0.421X+1.209C. The optimal stocking density was 210～255 thousand shrimps/hm^2 in Pacific white shrimp culture.
