In 2018 it was estimated that nearly 90% of the world’s marine fish stocks were fully exploited, overexploited or depleted.
Overfishing is defined as too many fish being caught so there are not enough adults to breed and sustain a healthy population (Marine Stewardship Council, n.d.).
In addition to overfishing, certain methods of fishing have a greater negative impact than others. For example, trawling and dredging can damage sensitive seabed habitats.

Illegal, unreported and unregulated (IUU) fishing can also have a hugely degrading impact on the ocean. IUU fishing harms fish stocks and the marine environment by illegally taking more than is allowed or by catching in ways that are harmful. Importantly, it also undermines the livelihoods and economies of coastal communities.
Intensive fish farms cause pollution and degrade wild fish populations through their use of fishmeal and fish oil to feed farmed fish, and chemicals such as fertilisers and disinfectants, as well as the spread of diseases and parasites.
All of these pressures mean there is an urgent need to:
rewild the sea and promote wild fish populations and marine and coastal habitats to recover
enhance natural processes including those that help mitigate climate change
