Abstract:

An experiment was conducted to determine effects of different salinities (1‰, 5‰, 10‰, 15‰, 20‰, 25‰, 30‰, 35‰, 40‰) on growth rates of two full-sib families of Litopenaeus vannamei. The results suggested that salinity has different effects on the two families. For family B03, no obvious differences in body length and body weight existed in salinity range from 10‰ to 40‰. The growth of family B08 changed obviously with salinity, which increased with salinity in the range of 1‰ to 15‰ but decreased when salinity varied from 15‰ to 40‰. The mean survival rate of family B03 was higher than that of family B08. Both families did not show good tolerance to salinity between 1‰ and 5‰. Our findings provide evidence for the selective breeding of new line of L. vannamei.

Key words: Litopenaeus vannamei, salinity gradient, growth, body length, body weight
