Marine fish around the world are already feeling the effects of climate change—and some are reeling, according to the first large analysis of recent trends. Rising sea temperatures have reduced the productivity of some fisheries by 15% to 35% over 8 decades, although in other places fish are thriving because warming waters are becoming more suitable. The net effect is that the world’s oceans can’t yield as much sustainable seafood as before, a situation that is likely to worsen as global warming accelerates in the oceans.
A silver lining is that the research suggests well-managed fisheries are more resilient in the face of rising temperature, says Rainer Froese, a marine ecologist with the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, who was not involved in the work. “We have to stop overfishing to let the gene pool survive, so that [the fish] can adapt to climate change,” he says. “We have to give them a break.”

The simple solution is to stop eating ocean fish; or, any fish for that matter. Now the guffs and the awe’s will likely follow. hahaha Your health will improve, as will that of the ocean. People do not need all that fat & oil in their diet. I eat algae oil for brain health, made right here in tanks in Nova Scotia {NS} To get out of this mess humans, will have to evolve whether they like it or not, despite tradition and culture. Recall, Naomi’s’ book title from 2014: This Changes Everything!
