摘要
设计了一个对虾养殖防病新模式，并进行了小规模试验，获得初步成功。 在 ４个３０～４０ｍ２的露天水泥池中，各放入 ３ｃｍ的大苗 ５００～７００尾（每亩约 １０ ０００ 尾），经 ９０余天的养殖，对虾成活率 ８０％左右，个体 １０ｃｍ，平均体重 ８０尾／ｋｇ；饵料 系数约１．５。新模式的立足点是防病，特点是设置一蓄水沉淀池，用含氯消毒剂处 理养殖用水，配备充气增氧设施，选择优质配饵，合理投喂，使各种水质理化因子及 生物因子尽量人为可控，从而使对虾养殖在一种相对稳定的生态环境中进行。
A New model of disease prevention for shrimp culture was designed, small scale experiment was conducted and desirable result observed. In four concrete tanks sized 30-40 m2, 500-700 juveniles of 3 cm length were respectively stocked (about 10 000 shrimp/mu). After 90 days culture the survive of about 80% with an average body length of 10 cm, 80 shrimps per kilogram and a feed conversation ratio of about 1. 5 were achieved. The characteristics of this new culture model is to prevent shrimp diseases by sedimenting and disinfecting culture water with chloride-disinfectant, installing aeration facility, feeding high quality feed and a reasonable feeding strategy. These measures may enable shrimps to grow in a relatively optimum ecological environment.
