When did the overfishing first become an issue?

Overfishing became a significant concern in the mid-20th century as industrial fishing techniques advanced, leading to the depletion of various fish stocks. The problem gained widespread recognition in the 1970s and 1980s when scientists and environmentalists began to document the declining populations of key species, such as cod in the North Atlantic. Increased demand for seafood and unregulated fishing practices exacerbated the issue, prompting calls for sustainable management and conservation measures.
