Latest Theory of Fish Decline
The Delta's decline that has nothing to do with pumping water to farmers, but the only people getting punished are farmers.
Nov 11, 2015
For years environmentalists have been telling us that the major problem with fish declines in California, and especially in the Delta, is the water being exported to farmers in Central California and residents of Southern California. We know there are other reasons, of course. There is the treated sewage in the form of ammonia from treatment plants around the Delta. There is the stripped bass that eats smelt and other fish.
In early 2011 the Delta Independent Science Board reported that there are over 40 potential causes for the Delta's decline. They also said they weren't in a position to rank them. Nevertheless, the only solution continued to be to reduce water exports to farmers. No matter how many studies and findings there are, the only solution is the same.
Now, there is another study finding yet another potential cause: climate change. The decline in fish numbers has been ongoing for half a century and the only consistent correlation is warming ocean temperatures.
So, here's another theory on the Delta's decline that has nothing to do with pumping water to farmers, but the only people getting punished are farmers.
All that water, all these years, through the Delta and out to sea to save the smelt when it was climate change all along doing all the damage.
And all the water washing down the San Joaquin River to save the salmon when climate change killed their chances long ago (Salmon Belong Where They Can Thrive - Not on the San Joaquin River),
Climate change a likely culprit for declines in ocean fish
Fish populations off California’s coast have plummeted more than 70 percent in the last four decades, and scientists’ best guess is that climate change is to blame.
The precipitous decline has occurred ecosystemwide in the California current, a stretch of the Pacific that runs from the Pacific Northwest to Baja California, according to a recently published study. The decline can’t be pegged on a lone cause, such as overfishing or chemical pollutants.
