Description:
This investigation has been carried out to complement the previous related study, aiming the Possibility of culturing white leg shrimp (L.vannamei) at higher densities of 50, 70 and 90 indiviuals/m^2. After 122 days rearing period, the highest mean weight of shrimp obtained at density of 50 indiviuals/m^2 (16.91± 2.43 g) with no significant difference with that obtained at 90 indiviuals/m^2 density (P≤ 0.05). Mean weight gain of the shrimp in the 70 indiviuals/m^2 density (14.35 ± 2.17g) was significantly lower than that at other densities (P≤0.05). Results showed no significant (P〉0.05) difference between survival rates, FCR and PER in the different treatments. The highest yield of 14008 kg/ha with the mean weight of 19.43 g/shrimp was obtained at the density of 90 indiviuals /m^2. According to the results of the present study it could be concluded that 90 indiviuals /m^2 could be adapted as suitable density for economically feasible culture of L.vannamei in earthen ponds in Chowibdeh site if the appropriate conditions are provided.
