Aquatic Pollution and Coastal Management

Unit 13 : Coastal zone and anthropogenic activities

13.11.Aquaculture
Aquaculture can potentially serious environmental impacts. These include the clearance of mangroves and other coastal vegetation for ponds, declining water quality caused by nutrient enrichment and oxygen depletion of out flowing water and the introduction of non-native species, which may escape the aquacultural ponds and disrupt natural ecosystem functioning. While aquaculture has great potential for alleviating the pressure on wild stocks, some caution is necessary. Sites and species used in aquaculture should be selected for their suitability in order to minimize impact on the environment.
