Objectives and Tasks

Objective Task
1. Coordinate activities with Columbia River commercial fishers and resource managers. a. Coordinate all objectives, tasks and activities to ensure that all impacts or take of fish, whether listed under the ESA or not, will be consistent with agreements, policies and management principles of the fishery managers of the Columbia River.
1. b. Coordinate selection of specific fishing times and places to ensure that the objectives of all parties will be met. Obtain necessary permits to conduct fishery.
1. c. Promote dialogue and participation by all parties affected by the development of selective fishing gear.
1. d. Host meetings as needed with involved and interested parties to refine work plans and report on progress.
2. Estimate the catch per set to +/- 10% at 95% confidence for the tangle net and conventional gill net fisheries. Estimate the age and size for each species caught to +/- 10% at 95% confidence for the tangle net and conventional gill net fisheries. a. Purchase and prepare gear, contract with fishermen, train technician. Consult with experienced tangle net operators.
2. b. Fish tangle net at several locations for several target species, document fishing.
2. c. Collect biological data about catch, tag salmon with numbered visual tag.
2. d. Compare the estimates of stock composition of the catch from the tangle net with the catch from a commercial gill net fishery.
3. Estimate the proportion of fish caught in the tangle net that are brought aboard dead (can not be revived) by species, to +/- 2% at 95% confidence for each set. a. Estimate the number of fish from each set that were brought aboard dead after capture in the tangle net.
3. b. Estimate the number of fish of each species, size, age and condition grade that were released live. For each fish released live, biological data will be collected to classify the fish.
3. c. Document the soak times, hang ratios, and net lengths that maximize the survival of captured fish.
4. For each species, estimate the pecentage of fish released from the tangle net that survive to complete their migration, to +/- 25% at 90% confidence. a. Notify as many people as possible who are likely to recover a tag about the study. Visit Columbia River sports groups, commercial fishing groups, hatcheries, and biologists in person.
4. b. Observe PIT tag detections on dams. Monitor jaw tag recoveries at counting windows on dams. Monitor recapture rates of tagged fish in our experiment and in nearby fisheries.
4. c. Hold fish for 24 hours in individual containers and observe condition at release.
4. d. Estimate the long-term survival of released fish by recovering tags at spawning grounds and hatcheries.
4. e. Radiotag 50 fish per year, representing different species and condition grades when brought on board. Relocate radiotagged fish for 3 days after release. Note subsequent relocations of radiotags during later surveys.
5. Test whether egg viability is affected by capture and release from the tangle net. a. Select up to three hatcheries where tagged fish are recovered and which have sufficient incubation space.
5. b. Spawn tagged fish into separate containers. Spawn untagged fish of similar size into separate containers. Rear to eyed stage.
5. c. Count number of live eggs per female and compare tagged to untagged fish.
6. Share results of experiment with tribal and non-tribal fishermen and resource managers on the Columbia River and in other areas where this technology might be viable. a. Prepare written annual report for distribution to interested parties.
6. b. Give oral presentations for interested parties and promote discussion. Travel to areas where interest is this technology is high.
6. c. Submit article to peer-reviewed journal at completion of study.

Other Budget Explanation

Schedule Constraints: Fishing may be restricted by the Columbia River managers, and by the weather. Insufficient tags released for the 1999 brood may inhibit completion of objectives 2, 3, 4, and 5 in FY1999, and 2000 brood tagged in late FY2000 will be recovered in FY2001.

Section 7. Abstract


On the mainstem Columbia River, salmon may be harvested in mixed stock commercial fisheries such that fishers targeting salmon from stronger runs inadvertently catch weaker species and stocks. Our goal is to evaluate tangle nets as selective fishing gear for exploiting strong anadromous fish stocks while allowing live-release of non-target fish species and stocks on the Columbia River. We will conduct a no-take commercial fishery using the tangle net on the lower Columbia River. Activities will be coordinated with Columbia River fishers and resource managers. The ability of the net to catch target fish and the survival of released fish will be evaluated. This project addresses Measure 8.3 (Develop alternative harvest opportunities) in the Columbia Basin Fish and Wildlife Program. The tangle net will be fished at different times for a variety of target species and the catch biologically characterized. In the first year one net will be fished, and in the second year, two will be fished simultaneously. Live fish brought on board will be tagged and biological data will be collected before release. To evaluate short-term survival, up to 20 salmon per fishing day will be held in individual containers for 24 hours before release or tagged with a radiotag for later relocation. Survival will also be estimated from tag recoveries. The composition of the catch from the tangle net will be compared to conventional gill net fisheries. At the end of this three-year project, we expect to be able to recommend whether tangle nets are a viable selective fishing gear and should be admitted into the fisheries. Our results will be presented in annual reports and submitted for publication in a peer-reviewed journal.
