A survey on effects of shrimp aquaculture on the coastal waters of Bushehr (Helleh and Mond)

The effects of aquaculture industry on the environment were evaluated by studying the water quality of Bushehr costal water during culture season 2005 and 2006. The variations of selected parameters such as total phosphorus, ammonia, chlorophyll a, pH, salinity and... Were monitored in effluent canal, influent canal and open sea in Helleh and Mond regions as monthly. Following occurrence of White Spot Disease (W.S.D) in the shrimp ponds of Bushehr province, shrimp culture suspended and entrance of effluent waters completely were blocked since August 2005, despite the absence of aquaculture sewage evaluation of environment and sampling were continued. During releasing of sewage of shrimp ponds to the coastal waters of Bushehr in Jun 2005, the average amount of ammonia in Helleh and Mond were obtained to be 0.161 mg/l and 0.194 mg/l, however the average amount of total phosphorus in Helleh and Mond regions were 0.149 mg/l and 0.043 mg/l, respectively. Although effluent water suspension, amount of ammonia and total phosphorus were increased in both region especially in June 2006. Comparing present data in Jun 2005 and recorded data from culture period 1997-2003 with permitable range of municipal and aquaculture waste show that; aquaculture industry on both regions have not had any obvious negative effect on the coastal waters of Bushehr but it seems if other sources of pollutions in the region is not controlled, then the aquaculture industry can contribute to occurrence of environmental problems.
