南美白对虾原产于南太平洋沿岸水域，以厄瓜多尔沿岸的分布最为集中，是世界养殖产量很高的三大优良虾种之一。它具有抗病力强，生长快，离水存活时间长，能适应低盐度，肉质鲜美，对饲料蛋白质需求量低，易于进行集约化养殖等特点。李广丽等对南美白对虾仔虾对盐度突变的适应性进行了研究，为南美白对虾虾苗淡化和放养时盐度的调节提供了依据。近几年来，浙江各地修建了许多家南美白对虾淡化苗厂，从事虾苗的淡化培 Penaeus vannamei native to the waters of the South Pacific coast to the distribution of Ecuador’s most concentrated, is the world’s high yield breeding one of the three fine shrimp. It has the characteristics of strong disease resistance, fast growth, long survival time from water, adaptability to low salinity, delicious meat, low requirement for feed protein and easy intensive culture. Li Guangli et al. Studied the adaptability of salinity mutation of Penaeus vannamei, which provided the basis for the salinity adjustment of P. vannamei shrimp and stocking. In recent years, Zhejiang Province, many of the construction of the South American white shrimp desalination plant, desalination in shrimp
