Environmental impacts in aquaculture
The impacts of aquaculture on the ecosystem have been complex. The aggregation of nutrients occurs when there is a high fish density in one location. Fish generate waste and their waste in the surrounding area has the potential to build up. This may deplete oxygen content, causing blooms of algae and dead zones. The release into the ocean of marine animal waste from aquaculture facilities will not only harm other species but will also contribute to contamination of nutrients. Water eutrophication, water quality, modification or degradation of natural habitats are the most common negative environmental impacts associated with aquaculture, introduction and transmission of aquatic animal diseases.
