Nitrogen and phosphorous budgets for integrated culture of whiteleg shrimp Litopenaeus vannamei with red seaweed Gracilaria corticata in zero water exchange system
In this study, a 2×3 factorial design with two levels of shrimp density (25 and 50 shrimp per m2) and three levels of red algae density (0, 200 and 400g per m2) was applied to calculate nitrogen and phosphorous budgets in the integrated culture of Litopenaeus vannamei with Gracilaria corticata during 45 days in a zero water exchange system. Juveniles of...

Abstract In this study, a 2×3 factorial design with two levels of shrimp density (25 and 50 shrimp per m-2) and three levels of red algae density (0, 200 and 400g per m-2) was applied to calculate nitrogen and phosphorous budgets in integrated culture of Litopenaeus vannamei with Gracilaria corticata during 45 days under zero water exchange system. Juvenile of L.vannamei (5.82 ± 0.11 g...
متن کاملEffects of temperature and salinity on nitrogenous excretion by Litopenaeus vannamei juveniles.
Excretion rates of ammonia-N, nitrite-N, nitrate-N, and dissolved organic nitrogen (DON) for juvenile Litopenaeus vannamei (3.85+/-0.83 g) were quantified in response to nine different combinations of temperature (24, 28, and 32 degrees C) and salinity (10, 25, and 40 ppt) under laboratory conditions. Results indicated that L. vannamei is ammonotelic, with ammonia-N accounting for 61.9-84.3% of...
متن کاملStudy on nursery growth performance of Pacific white shrimp (Litopenaeus vannamei Boone, 1931) under different feeding levels in zero water exchange system
Effect of different feeding levels on water quality, growth performance, survival rate and body composition of Pacific white shrimp Litopenaeus vannamei post larvae were studied in zero water exchange system. Shrimp post larvae with mean weight of 74.46± 6.17 mg were fed for 32 days in 300L fiberglass tanks containing 130L water at density of 1 post larvae L-1. There were five treatments includ...
