南美白对虾以其生长快,盐度适应范围广(0‰-4‰),饲料蛋白要求低、抗病能力强、肉质鲜嫩、出肉率高等特点,成为我国虾类养殖的主要品种,并迅速得到推广养殖。但淡水养殖南美白对虾产量较低,制约了南美白对虾在内陆地区的推广。产量低的主要原因是成活率低,经我们调查分析,影响成活率的重 Penaeus vannamei has become the main species of shrimp farming in China due to its rapid growth, wide range of salinity adaptation (0 ‰ -4 ‰), low feed protein requirement, strong disease resistance, fresh meat quality and high meat yield rate. Promptly promote breeding. However, freshwater aquaculture production of P. vannamei was low, which restricted the promotion of P. vannamei in inland areas. The main reason for low yield is low survival rate, after our investigation and analysis, affecting the survival rate of weight
