刀额新对虾又称基围虾、沙虾。对底质无严格的选择,广泛栖息于近岸浅海沙泥底海区。适应的水温为10～37℃,最佳生长温度为17～32℃。当天气寒冷,透明度大时隐藏在底质中,深度可达8～10厘米,适温期白昼也常潜伏于底质中,仅露出两眼和触须。黄昏时进行捕食,夜间活动较多。对盐度适应范围广,能在淡水中生长,也能在盐度为35％。以上的海水中生存。对低溶氧忍受力比较强。能在pH值为7.0～9.0的水中正常生活。
Knife new shrimp, also known as shrimp, shrimp. Strict selection of the substrate, widely inhabit the coast of shallow sea sand mud bottom area. Adapt to the water temperature of 10 ~ 37 ℃, the optimum growth temperature of 17 ~ 32 ℃. When the weather is cold and transparent, it is hidden in the sediment with a depth of up to 8 to 10 cm. During the suitable temperature period, the daytime is often lurked in the sediment, exposing only the two eyes and the tentacles. Predation at dusk, night activities more. To adapt to a wide range of salinity, can grow in fresh water, but also in the salinity of 35%. Survival in the sea above. Endurance of low dissolved oxygen is relatively strong. In the pH value of 7.0 to 9.0 in the normal life of water.
