Salmon fish7/2/2023 Competition: Evidence indicates non-native salmon species do not compete well against native species.Among the concerns addressed in that report: The department also requires fish transport permits to ensure fish are not at risk of disease.ĭNR owns aquatic lands on which aquaculture operations take place, and leases those lands to operators.Ĭounties issue shoreline permits to net pens.įish management issues of escaped Atlantic salmonĮxisting biological data strongly suggests that escaped Atlantic salmon do not pose significant risk to native fish populations, based on research outlined in a 1999 report. WDFW reviews permit requirements, fish escape prevention and response plans, and monitors the health of farm-raised fish in collaboration with the Northwest Indian Fisheries Commission fish health group. Here is a summary of key state agency roles:Įcology manages the state water quality permits required for commercial net pen operations. These relationships include WDFW's co-management of salmon and other species with the state's treaty tribes. Permitting and oversight of aquaculture operations in Washington waters involves multiple state agencies. There was no direct evidence of Atlantic salmon spawning or hybridized specimens. An analysis of otolith and scale samples strongly indicated that all of the captured juvenile fish were hatchery escapements and all of the adults were net pen escapees. Between 20, WDFW's Aquatic Invasive Species Unit conducted 882 surveys for the presence of Atlantic salmon across 174 water bodies, and collected 192 Atlantic salmon.In 2017, more than 100,000 fish escaped when a net pen facility containing about 305,000 fish failed near Cypress Island. Before 1996, no significant escapes of Atlantic salmon from pens in Washington were recorded.Risk to native fish by Atlantic salmon was determined to be low. In 1990, at the direction of the Legislature, WDFW published a programmatic environmental impact statement of net pen aquaculture.No adult Atlantic salmon returned as a result of the releases. The most recent effort by WDFW was in 1981, when attempted introductions were made via the release of cultured Atlantic salmon smolts. Numerous attempts were made in the 20th century by agencies on the Pacific coast to introduce and establish Atlantic salmon.Commonly expressed concerns surrounding escaped Atlantic salmon include competition with native salmon, predation, disease transfer, hybridization, and colonization.īased on WDFW's study, the evidence strongly indicates that Atlantic salmon aquaculture poses little risk to native salmon and non-salmon species.The Washington Department of Fish and Wildlife (WDFW) examined potential threats that escaped Atlantic salmon could pose to native species in a 1999 report, " Atlantic Salmon in Washington State: A Fish Management Perspective.".Atlantic salmon ( Salmo salar) are important worldwide in commercial aquaculture and recreational fisheries and are cultured commercially in marine net pens in Puget Sound.Monofilament recovery and recycling program.
