Abstract

The shrimp, Metapenaeus affinis, was reared in two types of basins with water salinities of (1 and 5) mg/L with initial weights of 1540 ± 278.75 mg and final weights of 1765 ± 273.91 mg and 1891.67 ± 324.66 mg, respectively. Weight gain was 225 ± 5 mg and 347 ± 47 mg, growth rate was 0.464 ± 0.082 mg and 0.678 ± 0.033 mg/day, and survival rates were 60% and 80%, respectively. Statistical analysis showed no significant differences (P≥0.05) between weight gain, growth rate, and growth rate of the shrimp rearing at the two ponds with different salinity levels (1 and 5) mg/L. Significant differences (P≤0.05) were found in feed conversion ratios and survival rates.
