Intensive culture system of Litopenaeus vannamei in commercial ponds with zero water exchange and addition of molasses and probiotics

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...

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...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
