“OVERFISHING”

OVERFISHINGOverfishing is a form of overexploitation where fish stocks are reduced to below acceptable levels. Overfishing can occur in water bodies of any size, such as ponds, rivers, lakes or oceans, and can result in resource depletion, reduced biological growth rates and low biomass levels.

OVERFISHING IN BANGLADESHThe Hilsa fish, called ‘Ilish’ in

Bengali, is of national importance to Bangladesh. It’s one of the country’s main staple foods. But increased demand for the fish, which is popular throughout South Asia, has led to pressure on the fish species. Not only is the Hilsa in trouble, but so are the 3 million fishermen, fisherwomen and fishery workers who directly or indirectly depend on the fish for their livelihood.

According to fish conversation act (1950) Jatka catching, transportation, marketing and sale are restricted from November to June in each year.

Causes of overfishingOvercapacity: All over the world, many fishing industries have huge vessels, equipment and technology that they can deploy deep into the oceans.Unsustainable Fishing: This involves using nets, fishing methods and other equipment that catch too much fish to a degree that they are endangered. It also involves catching other sea animals other than fish in the process. Economic and Food Needs: The amount of fishes that fishing industries bring ashore depends on the market and needs of consumers. In the past century, humans have multiplied in many folds and the need for food and fish has also multiplied.

Impact of overfishingEcosystems Destruction According to marine ecologists, unsustainable fishing is the greatest threat to ocean ecosystems. The practice destroys the physical environments of marine life, and distorts the entire food chain in the oceans.Economic ImpactSustainable fishing ensures that people’s livelihoods are protected and the fishing business is sustained. Overfishing does not guarantee that, and soon, big investments will go waste and people will be out of work.

Ghost FishingMany large fisheries stay for weeks and months in deep seas and sometime loose their nets. These nets continue to trap and catch fishes under the water and end up killing them.PollutionOil and liquid spills, chemical and solid elements discharged into the water by fishing boats, vessels and trawlers often hurt marine life.

WHAT CAN WE DO?Safe catch limits

A constantly reassessed, scientifically determined, limit on the total number of fish caught and landed by a fishery. Politics and short time economic incentives should have no role in this.

Controls on by catchThe use of techniques or management rules to prevent the unintentional killing and disposal of fish, crustaceans and other oceanic life not part of the target catch or landed.

Protection of pristine and important habitatsThe key parts in ecosystems need full protection from destructive fisheries; the spawning and nursing grounds of fish, delicate sea floor, unique unexplored habitats, and corals.

Monitoring and EnforcementA monitoring system to make sure fishermen do not land more than they are allowed to, do not fish in closed areas and cheat as less as possible. Strong monetary enforcement is needed to make it uneconomic to cheat.
