Background: Due to the fact that shrimp effluent is a factor for eutrophication of water resources and on the other hand is a good source of organic matter, so it can be used again to cultivate suitable species.
Aim: The possibility of laboratory modeling of integrated agriculture with seawater was investigated using shrimp effluent. Methodology: 1000 shrimps with an average weight of 0.5 g were purchased from Pars Abzistan Breeding Center and kept in fiberglass tanks at the Marine Fish Research Station of the Persian Gulf Research Institute of the Persian Gulf University of Bushehr. After the adaptation phase, the shrimps were randomly selected and distributed in two 4000 liter polyethylene tanks. After shrimp tanks, Gracylaria red algae were cultured in four 300 liter tanks with a volume of 200 liters. After Gracylaria algae reservoirs, four 300 liter polyethylene reservoirs with a dewatering volume of 200 liters were raised. Forty young juveniles with an average weight of 26±1 g were purchased from the Marine Fish Breeding Center of Imam Khomeini Port and kept in fiberglass tanks at the Marine Fish Research Station of the Persian Gulf Research Institute of the Persian Gulf University of Bushehr. After that, Donalilla microalgae were cultured in 300 liter polyethylene tanks (four tanks) with a dewatering volume of 200 liters, and finally Artemia was cultivated in four 300 liter polyethylene tanks with a dewatering volume of 200 liters. In this experiment, the effluent of the previous stage was used in each stage.
Conclusion: The results showed that Gracylaria, Donalila and Artemia do not perform relatively well in absorbing nitrogenous forms. This indicates that the use of these organisms as biological filters does not have the potential for ecologically sound action and does not help to improve water quality.
