Overfishing and Maximum Sustainable Yield

Analyzing fish stock assessments, bycatch rates, and the economics of global fishing fleets.

Overfishing and Maximum Sustainable Yield

The State of Global Stocks

According to the FAO, approximately 35.4% of global fish stocks are overfished, meaning they are fished at biologically unsustainable levels. This figure has risen steadily from 10% in 1974.

Common Misconceptions

A frequent error in media interpretation is confusing localized transient effects with global secular trends. The figures demonstrated here isolate the multi-decadal signal from seasonal noise.

Frequently Asked Questions

Is this reversible?

On human timescales, highly unlikely. The thermal inertia of the ocean means impacts will persist for centuries even if emissions cease immediately.

How accurate are these figures?

Based on the latest AR6 synthesis and prevailing primary literature. Uncertainties are inherent in coupled non-linear climate models.
