[Effects of salinity and Na+/K+ in percolating water from saline-alkali soil on the growth of Litopenaeus vannamei].
In order to develop shrimp farming with the percolating water from coastal saline-alkali soil, the effects of the salinity and Na+/K+ in this percolating water on the survival, growth, metabolism, and glutamic oxaloacetic transaminase (GOT), glutamicpyruvic transaminase (GPT) and Na+-K+-ATPase activities of Litopenaeus vannamei were investigated. The shrimps were cultured at the salinity 5, 10 and 15 and at the Na+/K+ ratios of 20, 40, 50, 60, 70 and 90 for 20 days. The results showed that the survival rate, growth rate, and enzyme activities of the shrimps were the highest at salinity 15, and the shrimps had higher survival rate, growth rate, and enzyme activities at the Na+/K+ ratios of 40 and 50, suggesting that after an appropriate preparation, the percolating water from coastal saline-alkali soil was available to culture the shrimps.
