Possibility of intensive whiteleg shrimp (Litopenaeusvannamei) culture in outdoor pond in Choeibdeh Abadan

Abstract

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/m2. After 122 days rearing period, the highest mean weight of shrimp obtained at density of 50 indiviuals/m2 (16.91± 2.43 g) with no significant difference with that obtained at 90 indiviuals/m2 density (P≤ 0.05). Mean weight gain of the shrimp in the 70 indiviuals/m2 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 /m2. According to the results of the present study it could be concluded that 90 indiviuals /m2 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.
