The fish trade involves the buying and selling of fish and seafood products, both domestically and internationally. This trade supports economies by providing jobs in fishing, processing, and distribution. It includes various species, such as salmon, tuna, and shrimp, which are harvested from oceans, rivers, and aquaculture farms. Sustainable practices are essential in the fish trade to prevent overfishing and protect marine ecosystems. Regulations and certifications, like those from the Marine Stewardship Council, help ensure that fish are sourced responsibly. Consumers are increasingly interested in knowing the origins of their seafood to make informed choices.
