fish populations
Marine species counts
Fish populations are the total numbers of fish in a given species, region, or ecosystem.
Marine biologists and fisheries managers track fish populations to assess ecological health and set catch limits: Salmon populations have declined sharply in recent decades.
The term appears frequently in discussions of overfishing, conservation, and environmental change.
