چکیده
This study aimed to determine the optimum stocking density that supported optimization of water quality and production white shrimp (Litopenaeus vannamei) ponds. was conducted in 2 different cycles, namely cycles 14 15 with densities each cycle, 94 150 shrimp/m2. Each cycle represented by ponds, ponds B5 B6. Experimental animals used were post-larvae stadia 9-10 (PL 9-10) a size 9-12 mm. parameters observed included (brightness, salinity, temperature, dissolved oxygen, pH, alkalinity, ammonium, nitrite) performance (average body weight, average daily growth, biomass, feed conversion ratio, survival rate, intake). Water rearing medium reached value at indicated higher oxygen (4.0-5.3 mg/l) lower ammonium (0.5-3.0 compared shrimp/m2 (4 0.0-5.0 mg/l; 1.0-3.0 mg/l). A showed than SR (18.20-19.77 g/shrimp; 0.30-0.48 g/day; 80.60-80.90%) FCR (1.11-1.33) (17.18-17.40 0.45-0.50 73, 92-78.32%; 1.64-1.75). The results this could affect performance.

متن کاملSuitability studies of inland well waters for Litopenaeus vannamei culture
The inland farming of penaeid shrimp in low-salinity waters is now de facto in many regions of the world, yet there is little information pertaining to the suitability of waters with various ionic compositions for shrimp culture. In the present study, short-term (48 h) survival of Pacific white shrimp, Litopenaeus vannamei postlarvae (PL), and long-term (4 weeks) growth and survival of juvenile...
