斑节对虾(Penaeus mondon Febricius)是广盐性动物,对盐度的适应能力很强。据报道班节对虾可耐盐度范围为0.2-70‰,变化范围在10-20‰之间对生长没有明显影响。但盐度变化对斑节对虾成活率的影响,没见到报道。盐度是影响斑节对虾成活率的主要因素之一,在斑节对虾养殖过程中,育苗场和养成场海水盐度往往不一致,有的甚至相差很大,致使有些养殖场投苗后成活率很低。由于连续干旱或暴雨成灾也会造成虾 Penaeus mondon Febricius is a broad-salt animal that is well-adapted to salinity. It has been reported that the shrimp can tolerate salinity range of 0.2-70 ‰, the range of 10-20 ‰ no significant impact on the growth. However, the impact of salinity changes on the survival rate of Penaeus monodon did not find any reports. Salinity is one of the main factors that affect the survival rate of Penaeus monodon. During the culture of Penaeus monodon, the salinity of seawater in nursery grounds and farms is often inconsistent, and some even vary greatly, resulting in some farms surviving Very low rate. Shrimp can also be caused by successive droughts or torrential rains
