global fish stocks

Global fish stocks refer to the total populations of fish available in oceans and seas that can be harvested sustainably. These stocks fluctuate based on natural factors and human activities like fishing. Overfishing—catching more fish than the population can replace—leads to declining stocks, risking the health of marine ecosystems and future food security. Sustainable management aims to balance fishing levels with the natural capacity of fish populations to ensure their long-term availability for both ecosystems and human use.
