Climate Change Making Fishes Move towards North
As per a newly published research in journal Nature, climate change is making fishes head towards north from around two decades so as to look for cooler areas. William Cheung, a scientist from University of British Columbia said in his paper, published on Wednesday, that there is probability of major changes in the fishery industry as the global fisheries are getting dominated by warm-water species.
Cheung is of the view that the results show that change in catch of fishery should be expected. And with that the fishing industry also has to adapt the changes in the new species. Various scientists till the time tried to look for the impact of climate change on gradually warming ocean but weren't able to find anything. So, Cheung took up the approach of fish to find out the changes.
For this study, Cheung linked the records of global fisheries with the fact that what temperature suits to which species. He then calculated something using the earlier analyzed data and calls its calculation as `mean temperature of the catch'. He was quoted as saying, "We looked at the change in mean temperature of the catch over the large ecosystems in the world. We find that after accounting for the effects of fishing as well as the effects of natural ocean variation, the mean temperature of the catch is increasing".
