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]
Destructive fishing practices are fishing practices which easily result in irreversible damage to habitats and the sustainability of the fishery ecosystems.Such damages can be caused by direct physical destruction of the underwater landform and vegetation, overfishing (especially of keystone species), indiscriminate killing/maiming of aquatic life, disruption of vital reproductive cycles, and ...
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.
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.

These methods facilitate destructive fishing practices that damage ocean ecosystems, resulting in overfishing. [ 2 ] Unsustainable fishing methods vary in scale, ranging from commercial-grade equipment (such as bottom trawling ) to consumer-grade equipment such as fishing rods and nets . [ 3 ]
Bottom dragging gear such as beach seines can damage corals by abrasion and fracturing. A beach seine is a long net about 150 meters (490 ft) with a mesh size of 3 centimeters (1.2 in) and a weighted line to hold the net down while it is dragged across the substrate and is one of the most destructive types of fishing gear on Kenya's reefs.

Less known than its beaches are Trinidad’s satellite islands and islets. Indeed, the country of Trinidad and Tobago is comprised of more than just its two main land masses.
