What percentage of fish are left?
An estimated 70 percent of fish populations are fully used, overused, or in crisis as a result of overfishing and warmer waters. If the world continues at its current rate of fishing, there will be no fish left by 2050, according to a study cited in a short video produced by IRIN for the special report.
Are fish going to be extinct?
Freshwater fish populations are collapsing. Nearly 1/3 of all freshwater fish are threatened with extinction. In 2020 alone, 16 freshwater fish species were declared extinct. Since 1970, mega- fish —those that weigh over 66lbs—have declined in number by 94% and migratory freshwater fish saw a 76 % decline.
