2021 Spring Chinook Mainstem Tangle Net Test Fishery
Mainstem Columbia River Tangle Net test fishing is conducted each spring on the lower Columbia River in Catch Areas 1B and 1C (Zones 2 and 3) to evaluate the current run in regards to timing, stock composition, mark rate, and other biological data. This test fishery provides additional information to fishery managers which aides in the in-season management of the recreational spring Chinook fishery and provides a long term dataset to be used for planning future spring fisheries.
Steelhead, unclipped Chinook, and sturgeon are released immediately or are placed in a recovery box to aid in collection of biodata then released after the fish recovers. Adipose-clipped Chinook are sold to offset costs of conducting the test fishery. Upon request some upriver Chinook may be retained by Columbia River Treaty tribal members to meet immediate ceremonial needs. If a mortality occurs for a non-retainable fish it is donated to a local food bank.
The 2021 test fishery occurred from March 15th until May 10th. Fishing was scheduled one day a week, primarily on Mondays. For the 2021 test fishing period, 134 adipose clipped Chinook (111 adults and 23 jacks) were retained and sold by the agency. Columbia River Treaty tribal members retained a total of 15 Chinook (4 upriver clipped and 11 upriver unclipped (1 of which was a jack)). A total of 2 Chinook (1 upriver unclipped adult and 1 lower river unclipped jack) were donated to a local food bank.

2020 Fall Pound Net Trap Fishery
The pound net trap consists of a series of pilings with netting attached and is designed to direct fish into a netted enclosure, from which they can be gathered into a livewell, sorted, and the harvestable fish retained while the non-harvestable fish are released alive after biological data have been collected. WDFW is conducting a test fishery of a pound net trap located in Cathlamet Channel, Wahkiakum County, to evaluate the viability of these traps as an alternative commercial fishing gear and to evaluate their economic performance. In addition, data are being collected on all encountered fish stocks, including stock-composition monitoring, salmonid migration patterns, and collection of Chinook and Steelhead genetic samples. The data collected will provide WDFW with information used to ensure that impact limits set under the Endangered Species Act (ESA) are not exceeded for Chinook, Coho, and Steelhead.
Steelhead, non-adipose clipped Chinook and non-adipose clipped Coho are released alive immediately after biological data have been collected. Adipose-clipped Chinook and adipose-clipped Coho are retained and sold by WDFW to offset costs of conducting test fisheries. If a mortality occurs of a non-retainable fish it is donated to a local food bank.
Test fishing occurred between Aug 28 - Oct 16, 2020. Data in the table represent all retained and released adult salmonids encountered at the pound net for this fishing period.

Total Chinook released includes 2 adipose-clip. Total coho released includes 3 adipose-clipped and 1 unknown clip.
One non-adipose clipped coho was donated after being mis-identified as adipose-clipped and retained.
- Oct. 12-13 2018: 20 adipose-clipped coho including 3 jacks, sold by agency. Released 1 Chum and 20 largescale suckers. One adipose-clipped A-run steelhead was donated after being mis-identified and retained

2018 Spring Chinook Mainstem Tangle Net Test Fishery
Mainstem Columbia River Tangle Net test fishing is conducted each spring on the lower Columbia River in Catch Areas 1B and 1C (Zones 2 and 3) to evaluate the current run in regards to timing, stock composition, mark rate and other biological data, and to provide a long-term dataset. This test fishery provides additional information to fishery managers which aides in the in-season management of the recreational spring chinook fishery. A test fishing summary can also be found on ODFW's website.
Steelhead, wild chinook and sturgeon are released immediately or are placed in a recovery box to aid in collection of biodata then released after the fish recovers. Adipose-clipped chinook are sold to offset costs of conducting the test fishery. Upon request some upriver chinook may be retained by Columbia River Treaty tribal members to meet immediate ceremonial needs. If a mortality occurs for a non-retainable fish it is donated to a local food bank.

Spring Chinook Cathlamet Channel Research Test Fishery
The Washington Fish and Wildlife Commission in 2013 adopted the Columbia River Basin Salmon Management Policy (# C-3620), which includes guidance to "seek to phase out the use of non-selective gill nets in non-tribal commercial fisheries in the mainstem Columbia River, and transition gill net use to off-channel areas" by 2017.
In response to these directives, WDFW re-examined potential sites for off-channel "Select Area Fishery Enhancement" (Select Area) for rearing spring chinook (Oncorhynchus tshawytscha), and determined the Cathlamet Channel to have the most potential as a suitable location. The Cathlamet Channel is located in Wahkiakum County and is a side channel of the mainstem Columbia River running from approximately river mile 38 to river mile 47.
To assess the Cathlamet Channel as a potential Select Area site, research test fishing was initiated in 2013 to determine the run timing, abundance and stock composition, mark rate and other biological data of salmon returning during the late winter and spring time frame. From 2014-2018, spring chinook have been acclimated and released from net pens in Cathlamet Channel. Test fishing is used to evaluate returns of net pen fish to Cathlamet Channel.
Steelhead, wild chinook and sturgeon are released immediately or placed in a recovery box to aid in collection of biodata , then released after the fish recovers. Adipose-clipped chinook are sold to offset costs of conducting the test fishery. Upon request some upriver chinook may be retained by Columbia River Treaty tribal members to meet immediate ceremonial needs. If a mortality occurs for a non-retainable fish it is donated to a local food bank.
Test fishing typically occurs on Mondays and Thursdays from late February through early May.
