Warming oceans and drying fisheries
Increasing ocean temperatures adversely affect fishing economies worldwide. Due to rising temperatures, several fish leave to find cooler water to inhabit. A new study finds tropical nations of Northwest African countries vulnerable to this migration of fish. Especially the nations reliant on fishing economies. Moreover, it could not find any policy interventions to help compensate potential losses. Kimberly Oremus, an assistant professor, said researchers were unable to find any law on what happens when a fish leaves a nation’s Exclusive Economic Zone (EEZ). These zones were established to give a country national jurisdiction over a fish resource. The study also predicted that north west African EEZs could lose 6-25% of their fish species by 2050. Another 30-58% of fish species could be lost by 2100, in moderate to severe scenarios. In addition, researchers examined 127 international fisheries argeements. However, they were unable to find any preparation for the exit of stock, climate change or range shifts. Oremus said policy makers should think about compensation, a measure which could prevent over-fishing.
