Deep-sea fisheries are those that take place at depths ranging from 400-500 m to 1600 m.
Most of these fisheries sprang up at the end of the last century in response to the decline and sometimes the collapse of traditional stocks.
Although some of the commercial species caught at these depths are commonly known and other captured species may not be.
Long lifespan, late sexual maturity, slow growth and low fertility rates make these species very vulnerable to overfishing.
Deep-sea species are generally associated with vulnerable habitats of interest such as seamounts or deep-sea coral reefs.
Fishing gear commonly deployed in these fisheries has an impact on marine ecosystems, through by-catch of non-targeted species, as well as on marine habitats.
Oceana is working towards the sustainable exploitation of deep-water species and the protection of the habitats on which they depend.
