What term describes a situation where the number of fish caught is greater than the rate at which they reproduce?

Explanation:
Removing fish from a population faster than they can reproduce means the stock can’t replace itself, so the population declines. This situation is known as overfishing. Because fish are being taken out quicker than new ones are born and mature, the available breeding stock shrinks and future catches drop, sometimes to the point where the fishery collapses. Other terms describe different ideas: overhunting targets land animals, not aquatic ones; overfarming refers to agricultural land or crops, not wild fish populations; overpopulation describes a population size that exceeds the environment’s ability to support it, not the rate of harvesting. Sustainable fishing aims to keep harvest within the population’s natural reproductive capacity to prevent overfishing.
