Overfishing: A Global Environmental Threat to our Oceans

Overfishing A Global Environmental Threat to Our Oceans What is Overfishing? Overfishing occurs when more fish are caught than the population can replace through natural reproduction. Gathering as many fish as possible may seem like a profitable practice, but overfishing has serious consequences. The results not only affect the balance of life in the oceans, but also the social and economic of life. well-being of the coastal communities who depend on fish for their way Causes Effects Marine Lite Imbalance Access Fisheries Open Pirate Fishing Management Fishing Food Security Poor Decreased Subsidies Areas of Protected Government Lack Economic Loss Fishy Figures One in Five $25 Billion Three Quarter people on this planet depends on fish as the primary source of proteins is the value of the fish trade for developing countries per year, making it their most significant traded food product. of the world's fish stocks are being harvested faster than they can reproduce. The Impact Fish Stock Exploitation - 52% Fully Exploited- Unless the current situation improves, stocks of all species currently fished for food are predicted to Collaspe By 2048 Depleted 17% Overexploited The Dying Species of Tuna Overfishing causes Pacific Bluefin Tuna numbers to drop to 96% Skipjack Tuna Yellowfin Tund Near Threatened Yellowfin Tuna are among the larger tuna species, but is significantly smaller than the Atlantic and Pacific bluefin Least Concerned Skipjack is the most fecund of the main commercial tunas, and its population is considered sustainable Albacore Tuna Bigeye Tuna against its current consumption. Near Threatened Vulnerable tunas. To avoid overfishing of Albacore Tuna, the National Marine Fisheries Service and the Bigeye Tuna are amongst the tuna species most threatened by overfishing. The removal of large numbers of juvenile bigeye, before they reach breeding age, is a major concern to fisheries managers, scientisits and sport fishermen. Bluefin Tuna State Department work through international management forums to regulate tuna fisheries. Endangered Bluefin are the largest tuna. 90% of specimens currently fished young fish that have not yet reproduced.
