Ocean Plankton Extinction Could Bring Local Fisheries Down With It

Calanoid copepods are a plankton species that are a vital food source for fish larvae and therefore important for all commercial fisheries.

Major heattrapping gases emitted as a result of human activities have caused Global Warming over the past century, raising the average global temperature by about 1°F (0.6°C). Oceans respond more slowly to this change, though it has been recorded that the warming has occurred at a depth of about 2,300 feet (700 meters), where most marine life thrives.

 
Tiny sea creatures, ocean plankton, are facing looming extinction because of these rising ocean temperatures. Research led by Deakin University (Warrnambool, Australia) and Swansea University (UK) has found that a species of cold water plankton in the North Atlantic, that is a vital food source for fish such as cod and hake, is in decline as the oceans warm. This will put pressure on the fisheries that rely on abundant supplies of these fish.

 “There is overwhelming evidence that the oceans are warming and it will be the response of animals and plants to this warming that will shape how the oceans look in future years and the nature of global fisheries,” explained Deakin’s professor of marine science, Graeme Hays.
