Business and biodiversity :: Fishery

Fishing can have direct and indirect effects on biodiversity. Apart from direct effects on certain target species also other species of fish, birds and mammals are effected by changes in the ecosystem or because they are taken as by-catch. Fishery can also have other effects on biodiversity as fishing equipment can spread disease or alien species.
Aquaculture produces table fish, clams and crayfish and also restocking fish for sport. The direct effects of aquaculture on biodiversity are for example escapes from fish and shellfish cultures and the spreading of disease to wild stock. Further eutrophic discharge such as surplus fodder and excrements also has an effect on the local environment.

Environment and Fisheries (DG Environment)

Europe’s fishing industry has a vital interest in ensuring the conservation of marine ecosystems as all fishing and aquaculture activities depend on a plentiful supply of quality marine resources. The overexploitation of fish stocks has a devastating impact both on Europe’s marine life and fishing industry. The EU’s Common Fisheries Policy (CFP) puts in place a series of measures designed to reduce and eliminate over fishing. The ultimate goal is to reach a sustainable balance between the needs of the fishing sector and the available fish stocks.
