Climate change threatens extinction for 82 percent of California native fish

Salmon and other native freshwater fish in California will likely become extinct within the next century due to climate change if current trends continue, ceding their habitats to non-native fish, predicts a study by scientists from the Center for Watershed Sciences at the University of California, Davis.

 

The study, published online in May in the journal PLOS ONE, assessed how vulnerable each freshwater species in California is to climate change and estimated the likelihood that those species would become extinct in 100 years.

 

The researchers found that, of 121 native fish species, 82 percent are likely to be driven to extinction or very low numbers as climate change speeds the decline of already depleted populations. In contrast, only 19 percent of the 50 non-native fish species in the state face a similar risk of extinction.

Is that,that the fish will become extinct period,or extinct from california?

Here in our native cornish waters,changes are occuring.

Gilthead bream,a species from mainly south of the channel is now quite common here in the summer.

Great fish they are too,both to eat and sell.

Think it's a case of 6 of one and half a dozen of another.

Freshwater fish in California. I agree there has been a northward movement of fish in Cornish waters. The Plymouth Oceanography group have done a study on this but I don't have it to hand.
