We are generally surprised by the overall lack of information on the economics of California’s commercial and recreational salmon fisheries.

So as oceans heat up, a fish’s metabolism accelerates to cope with the rising temperatures and they need more oxygen to sustain their body functions.
But fish gills do not grow at the same pace as the rest of their body, resulting in a decline of oxygen supply and in growth.

At the same time, there were a million more Central Valley salmon being harvested each year in sport and commercial fisheries along the coast and in the rivers of the Central Valley.

Although the report at first blush appears to be very pessimistic, a closer read reveals a more optimistic view that “most of these fishes can continue to persist if appropriate actions are taken.” The authors have stated that they “are optimistic that positive change is imminent and that if the solutions are fully implemented, many of the species reviewed in the…report will thrive in the future.” Importantly, “the time to act is now” according to CalTrout.

Efforts to restore fish passage and river habitats over the past several decades have paid off quite remarkably, but those efforts are now in jeopardy due to the recent drought and impending changes in water management in the Central Valley and Butte Creek.

Dan Farber writes, “President Trump ordered EPA and the Army Corps to review the Obama Administration’s WOTUS rule, which sets expansive bounds on federal jurisdiction over water bodies and wetlands.
