Editing Fish farming (section)

=== Ecosystem impacts ===
The large number of fish kept long-term in a single location contributes to [[habitat destruction]] of the nearby areas.<ref>{{cite journal|last1=Naylor|first1=RL|last2=Goldburg|first2=RJ|last3=Mooney|first3=H|display-authors=etal|year=1998|title=Nature's Subsidies to Shrimp and Salmon Farming|journal=Science|volume=282|issue=5390|pages=883–884|bibcode=1998Sci...282..883N|doi=10.1126/science.282.5390.883|s2cid=129814837}}</ref> The high concentrations of fish produce a significant amount of condensed faeces, often contaminated with drugs, which again affects local waterways.

Aquaculture not only impacts the fish on the farm, but it also influences other species, which in return are attracted to or repelled by the farms.<ref name=":0" /> Mobile fauna, such as crustaceans, fish, birds, and marine mammals, interact with the process of aquaculture, but the long-term or ecological effects as a result of these interactions is still unknown. Some of these fauna may be attracted or demonstrate repulsion.<ref name=":0">{{Cite journal|last1=Callier|first1=Myriam D.|last2=Byron|first2=Carrie J.|last3=Bengtson|first3=David A.|last4=Cranford|first4=Peter J.|last5=Cross|first5=Stephen F.|last6=Focken|first6=Ulfert|last7=Jansen|first7=Henrice M.|last8=Kamermans|first8=Pauline|last9=Kiessling|first9=Anders|date=2017-09-19|title=Attraction and repulsion of mobile wild organisms to finfish and shellfish aquaculture: a review|journal=Reviews in Aquaculture|volume=10|issue=4|pages=924–949|doi=10.1111/raq.12208|issn=1753-5123|url=https://archimer.ifremer.fr/doc/00406/51737/52435.pdf|doi-access=free}}</ref> The attraction/repulsion mechanism has various direct and indirect effects on wild organisms at individual and population levels. The interactions that wild organisms have with aquaculture may have implications on the management of fisheries species and the ecosystem in relation to how the fish farms are structured and organized.<ref name=":0" />
