    1. reduction of essential nutrients
      1. reduced phytoplankton concentrations
      2. Accumulation of waste
        1. increased activity of benthic fauna
          1. smothering of light-dependent plants
            1. depletes oxygen supply
            2. Impacts of farming structures
              1. alters hydrodynamics of an area
                1. organic matter build up
                  1. detrimental impact on seagrass beds
                  2. Sustainability is subject to individual factors
                    1. area hydrology
                      1. waste from cultured species
                      2. Genetic shifts in wild populations due to species translocation
                        1. Introduction of exotic pathogens and infection
                          1. Fish are free from environmental contaminants
                            1. Competition with native species and escapees
                              1. Changes to environmental carrying capacity
                                1. Hybridization between endemic and translocated species
                                  1. Chemical usage prevents accumuation of heavy metals in the environment
