Pond production of Pacific white shrimp (Litopenaeus vannamei) fed high levels of soybean meal in various combinations

摘要: Abstract The objective of this study was to demonstrate the feasibility four diets formulated contain high levels soybean meal in combination with either poultry by-product, fish meal, distiller's dried grains solubles, or pea production for L. vannamei . Outdoor ponds and tanks were utilized evaluate response shrimp over culture period. pond trial conducted 0.1-ha stocked juvenile shrimps (mean weight ± S.D., 0.038 ± 0.004 g) at 35 shrimp m −2 cultured under standardized conditions 18 weeks. same dietary treatments plus a commercial reference diet offered (initial weight 2.1 g) maintained outdoor (800 L) 12-week results demonstrated that final ranged between 5054 5265 kg ha −1 , mean varied from 15.98 16.28 g, survival ranging 86.6 93.7%, FCR 1.32 1.37. There no differences (P ≥ 0.05) notable trends variables among different test diets. Shrimp reared confirmed these findings. Average weights 18.53 19.00 g, 97.3 98.7%, 1.30 1.33. tank also showed weight, survival, Diet containing partial fishmeal benefit on growth performance L comparing combinations solubles meal. Therefore, studies practical feeds had negative impact performances
