Chinook, Steelhead

The sorting by species and passage efficiency of Chinook salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss) through the WESS-WFTS was assessed.

the conclusion

PNNL found that the WESS-WFTS was able to sort the fish by size, few fish had external injuries, and few unexpected events (e.g. backward transport, discontinuous transport) occurred. PNNL results support the use of the WESS-WFTS as an effective transport system for adult salmonids when used in conjunction with a volitional fishway entrance.
