Overfishing has led to unsustainable depletion of global fish stocks, with 52% of stocks fully exploited, 20% overexploited, and 7% depleted. If overfishing continues at current rates, fish populations will further decline and collapse is expected by 2050, disrupting marine ecosystems and harming economies and food security. Specific concerns include declining tuna populations, with the Mediterranean bluefin tuna facing imminent extinction without fishing reductions.

6. The graph points out that current levels of fishing are obviously unsustainable.

7. These 10 ecosystems were studied for their MMSY, or multi-species maximum sustainable yield. Fishing below MMSY provides ecosystems with a chance to recover.

12. Explosive fishing – the use of dynamite or other explosives to kill fish. Causes for major destruction of reef. (15) Long-line fishing – long baited hooks used to catch swordfish, tuna, sharks, birds, and turtles. They are estimated to kill 180,000 birds worldwide every year. (11)
