在水温24~25℃条件下,凡纳滨对虾幼虾在碱度为10.10~38.78 mmol/L、盐度为0.100%~0.350%、pH 8.5~9.5的碳酸盐类盐碱水环境中,饲养15 d,存活率为70%~50%,平均体长增长量1.72~0.52 mm/d,并随着盐碱化程度的提高都呈下降趋势。水环境因子对幼虾生长的影响存在着多因子间的相互作用。K+质量浓度、pH、碱度、离子系数以及Ca2+/Mg2+值、Na+/K+值对幼虾体长增长量的影响都不显著(P>0.05)。Ca2+、Mg2+质量浓度、Ca2++Mg2+总浓度和盐度可能是东北地区碳酸盐类盐碱水域影响对虾生长的主要环境因子;高盐碱环境驯化可提高幼虾存活率及其生长性能。
Under the conditions of water temperature of 24 ~ 25 ℃, juvenile Litopenaeus vannamei was bred in the carbonate saline-alkali water environment with the alkalinity of 10.10-38.78 mmol / L, the salinity of 0.100% -0.350% and the pH of 8.5-9.5 The survival rate was 70% ~ 50% and the average body length increment was 1.72 ~ 0.52 mm / d for 15 d, which showed a decreasing trend with the increasing of salinization degree. Water environmental factors on the growth of juvenile shrimp there are many factors between the interaction. K + concentration, pH, alkalinity, ionic coefficient, Ca2 + / Mg2 + and Na + / K + had no significant effect on the growth of juvenile shrimp (P> 0.05). Ca2 +, Mg2 + concentration, Ca2 + + Mg2 + concentration and salinity may be the main environmental factors that affect the growth of shrimp in carbonate saline-alkali waters in northeast China. Domestication of saline-alkali soil may improve the survival rate and growth performance of juvenile shrimp.
