Shrimp culture, Litopenaeus vannamei in the closed recirculation system
The project carried out at Shrimp Research station of Bandargah in 2011 to determine the production parameters such as; Average body weight, production, survival and feed conversion ratio in closed- recirculating aquaculture system for shrimp culture. This project was performed in 4 m3 fiberglass tanks. 3 tanks was chosen for the control and 3 were assigned to treatments. Considered Species in this treatment was white shrimp (Litopenaeus vannamei) that with a density of 60 pieces per square meter, and was reared for 90 days. Culture in control as usual and change water regularly, but the treatments did not change water during the period of culture. Water in the treatment tanks was going to turn the filter system and waste was removed by mechanical and coal filter embedded in the route, and after filtering was transferred to the wastewater tank. Wastewater was aerated in this tank and after 24 hours was pumped out and return to treatments tanks. In the final of project, mean weight, survival rate and production for control and treatment, was respectively, 18.27 ± 2.84 and 20.70 ± 1.47 g, 73.83 ± 4.14 and 77.17± 13.66 percent, and 0.81 ± 0.14 and 0.97 ± 0.23 kg/m^2. Statistical analysis results show that there are no significant differences found between treatments and control (P> 0.05), although in all the above criteria, the relative improvement was achieved to compared of control. But the results of feed conversion ratio was 1.27 ± 0.16 for treatments that are significantly different (P <0.05) with controls (1.56 ± 0.23). This result showed that efficiency of the food was better in closed- recirculating shrimp culture system.
