Nitrogen and phosphorous budgets for integrated culture of Litopenaeus vannamei with red sea algae Gracilaria corticata under zero water exchange system

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...
