Research

The Fisheries Project functions as a research and fish production program. Staff, with help from the fishing community, is experimenting with various methods to improve fish survival and reduce impacts on wild and endangered species.

One strategy is to release the fish from the pens at high tide after dark. Because all the pens are influenced by daily tidal currents, the fish are flushed out by the outgoing tide. Research has shown that juvenile salmon go with the flow.

 

Releasing the fish under the cover of darkness significantly reduces the chance of birds eating the fish on their way to the ocean. Predation by double-crested Cormorants, Caspian terns and other birds accounts for the consumption of substantial numbers of Columbia River smolts on their route to the ocean.

  

In a project to reduce bird predation, project staff, in collaboration with ODFW's Gnat Creek hatchery, used a below-water feeding method to prevent fish from becoming accustomed to feeding at the surface. In another pilot project, entire net pens were floated from their estuarine site in Youngs Bay into the mainstem of the Columbia, where fish were released into deeper waters.
