However, latest estimates suggest that if global fisheries had been better managed, 16 million tonnes more seafood could have been harvested every year, helping to feed a burgeoning population .
The global population is set to reach 10 billion by 2050  and food production urgently needs to be made sustainable and equitable to ensure healthy diets for all. Effective management of fisheries allows stocks and ecosystems to recover, in turn increasing the amount of fish that can be sustainably harvested in perpetuity.
Dr Rohan Currey, Chief Science and Standards Officer, Marine Stewardship Council said: “Tackling over-fishing is a ‘win-win’ for our planet. By conserving our rich marine resources, we also enable more people to have the protein they need to live healthily. We know the practises that need to be adopted in order to enable sustainable fishing. What we need now is international will and cooperation to implement these across all waters, borders and species globally. Future generations have the right to sustainable food sources. As the global population continues to rise, the need to harness our natural resources responsibly is more urgent than ever.”
In recent years, more fisheries than ever before have been adopting sustainable fishing practices. In 2020 there were 409 fisheries around the world certified to the MSC’s sustainability standard, with another 89 undergoing assessment . To be MSC certified, a fishery must show the fish stock is healthy, that it minimises its impact on the environment and has effective management in place.
However, to accelerate change, fisheries need the support of governments to ensure that catch limits are in line with scientific advice, that illegal, unregulated and unreported fishing is tackled, and that harmful subsidies which encourage over-fishing around the world, are eliminated.
