Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
Fish density dwindled to 9.8 fish per 100 m 2 between 2001 and 2006. [17] Overfishing has reduced the herbivorous fish that keep algae populations in check and it has caused a phase shift from coral reefs to algae reefs. [5] Today, algae covers 24% of the reefs where corals once stood. [5] By 1960, fish biomass was reduced by 80% due to ...
The overfishing list reflects species that have an unsustainably high harvest rate. NOAA also keeps a list of overfished stocks. Those are species that have a total population size that is too low.

Overfishing is occurring in one third of world fish stocks, according to a 2018 report by the Food and Agriculture Organization of the United Nations. [9] In addition, industry observers believe illegal, unreported and unregulated fishing occurs in most fisheries, and accounts for up to 30% of total catches in some important fisheries. [10]
The average weight of a sheepshead is 1.4 to 1.8 kg (3 to 4 lb), but some individuals reach the range of 4.5 to 6.8 kg (10 to 15 lb). [11] This species was subjected to overfishing in the past, and is again becoming more important to commercial fisheries in the Gulf of Mexico as more desirable species, such as red drum (Sciaenops ocellatus ...
A Nassau grouper, E. striatus, ambushes its prey on Caribbean coral reefs. The Nassau grouper is a medium to large fish, growing to over a meter in length and up to 25 kg in weight. It has a thick body and large mouth, which it uses to "inhale" prey. Its color varies depending on an individual fish's circumstances and environment.
The method of fishing depends on the type and size of the fish to be caught. Trawling is used to catch shrimp, carite, snapper and cavali. The main catches from seine and gill nets are king fish, shark and carite. Fish pot catches are red snappers and jacks. Fishing is a year-round activity in the Caribbean and it directly employs thousands of ...
