An evaluation of stocking density on the intensive production of juvenile brown tiger shrimp (Penaeus esculentus)
چکیده انگلیسی

Brown tiger shrimp (Penaeus esculentus) were intensively grown from PL17 to approximately 1.0 g in a tank system with artificial substrates (AquaMat®). Shrimp growth and survival performance were compared between shrimp stocked at a density of 5720 and 11,430 m− 3. Mean shrimp weight was significantly higher (P < 0.05) after 56 d culture, when stocked at 5720 shrimp m− 3 (1.46 ± 0.11 g) compared to 11,430 shrimp m− 3 (1.04 ± 0.05 g). When harvested after 56 d, shrimp survival was 31.9 ± 12.0% at a density of 5720 m− 3, which equated to a mean biomass of 2.52 ± 0.81 kg m− 3. At a density of 11,430 m− 3, shrimp survival was 21.2 ± 2.7%, which equated to a mean biomass of 2.49 ± 0.19 kg m− 3. There was no significant difference (P > 0.05) in survival and biomass between the two stocking densities. Increasing the stocking density from 5720 to 11,430 shrimp m− 3 did not significantly increase shrimp biomass production and resulted in greater production costs and greater risk of losing stock.
