Anchovy sustainability varies depending on the specific species and region. Overall, anchovy populations can be abundant and resilient, making them a relatively sustainable choice. They reproduce quickly and have short lifecycles. Wild-caught anchovies are often harvested using purse seining or netting methods, which can have low bycatch rates. Some regions have implemented strict management measures to protect anchovy stocks and prevent overfishing. Anchovy fish farming is less common but has been explored as a potential alternative to ease fishing pressure; however, it presents challenges in terms of sustainable feed sources and potential impacts on the environment. It's important to choose anchovies from well-managed fisheries and sustainable sources to support their long-term viability.
