Collaboration in Time of Crisis: Responding to the Oroville Dam Emergency

Multiple partner agencies provided assistance to salmon & steelhead stranded as a result of the deteriorating Oroville Dam spillway, as well as to fish in the Feather River hatchery downstream.

Person cleaning mud and sediment from the steelhead eggs. As a result of the damage to the Oroville Dam spillway, sediment levels in the Feather River increased significantly over a short period of time. The Feather River Hatchery obtains its water directly from the Feather River for operation of the facility. In order to reduce the impacts associated with high levels of turbidity, Feather River Hatchery staff worked continually to clean mud and sediment from the steelhead eggs, housed in "egg stacks," which were too sensitive to be moved elsewhere. This extensive effort helped save approximately 700,000 threatened California Central Valley steelhead, while engineers from the California Department of Fish and Wildlife developed alternative means of bringing clean water to the developing eggs.

Heavy Southern California Rain Brings Life Back to Drought-Stricken Creeks

After five years of drought, southern California has finally received some much-needed rain. Many creeks have been dry and disconnected from their estuaries and the ocean this year due to drought. Now, the water is flowing again! This is a welcome repriev

NWFSC Wins AAFCO Approval of Taurine in Fish Feeds

All over the world, the demand for delicious, safe, and healthy fish is increasing, to the point that fish farming, or aquaculture, is now the fastest-growing food-producing sector in the world. Consequently, the demand for feed ingredients, especially fish meal and fish oil, has increased dramatically in recent years. If growth in this industry is to be sustained, we need to find viable replacements for fish meal and fish oil in aquaculture feeds.

Ocean Acidification to Hit West Coast Dungeness Crab Fishery, a New Assessment Shows

The acidification of the ocean expected as seawater absorbs increasing amounts of carbon dioxide from the atmosphere will reverberate through the West Coast’s marine food web, but not necessarily in the ways you might expect, new research shows.

The study modeled the potential risks of ocean acidification (under a future decrease in pH) on the West Coast marine food web and fisheries over 50 years, from 2013 to 2063. Most fisheries we explored were negatively affected by a future decrease in pH. State-managed fisheries were the most affected, particularly because of the strong decline in valuable Dungeness crab. Coastal pelagic fish like sardines were only slightly affected. Credit: NOAA Fisheries

Early Action Key to Reducing Sea Lion Impacts on Salmon, New Study Finds

A new study used the same kind of models that scientists use to track disease to instead examine how some California sea lions have learned to prey on salmon gathering to ascend fish ladders at Bonneville Dam.
