Pacific Fisheries Bycatch Program

Prior Projects



Pacific Hake Midwater Trawl Fishery
Examining how artificial illumination (e.g., LEDs) can influence the behavior and escapement of Chinook salmon out a bycatch reduction device. Collaborators: PSMFC, Northwest Fisheries Science Center Marine Habitat Ecology group (NWFSC MHE), and F/V Miss Sue.

Evaluation of flexible sorting grid excluders designed to reduce salmon and rockfish bycatch. Collaborators: PSMFC, NWFSC MHE, F/V Perseverance, F/V Raven and Foulweather Trawl.

Testing of an open escape window bycatch reduction device designed to reduce Chinook salmon and rockfish bycatch. Collaborators: PSMFC, NWFSC MHE, F/V Miss Sue, F/V Predator, and Foulweather Trawl.

Groundfish Bottom Trawl Fishery
Evaluating how illuminating the headrope of a selective flatfish trawl can affect catches of groundfishes, including Pacific Halibut. Collaborators: PSMFC, NWFSC MHE, SINTEF, and F/V Miss Sue.

Examining the size-selection characteristics of T90 mesh and diamond mesh codends and evaluating their efficacy to improve catch utilization. Collaborators: PSMFC, NWFSC MHE, Oregon Department of Fish and Wildlife (ODFW), F/V Last Straw, and NET systems.

Evaluation of selective flatfish sorting grid bycatch reduction devices designed to reduce catches of rockfishes, sablefish, and Pacific halibut in the nearshore flatfish fishery. Collaborators: PSMFC, NWFSC MHE, SINTEF, F/V Miss Sue, and Foulweather Trawl.

Testing of flexible sorting grid excluders designed to reduce Pacific halibut bycatch. Collaborators: PSMFC, NWFSC MHE, F/V Miss Leona, F/V Miss Sue, Dantrawl, and Foulweather Trawl.

Ocean Shrimp Trawl Fishery
Determining how catches of eulachon, juvenile groundfishes, other fishes, and ocean shrimp are affected by altering the level of artificial illumination (e.g., number of LEDs) along an ocean shrimp trawl fishing line. Collaborators: PSMFC, ODFW, SINTEF, NWFSC MHE, and F/V Miss Yvonne.

Investigating how artificial light in the vicinity of the rigid-grate bycatch reduction device and along the fishing line of an ocean shrimp trawl can alter eulachon, groundfishes, and ocean shrimp catches. Collaborators: PSMFC, ODFW, and F/V Miss Yvonne.

Testing footrope modifications designed to reduce the bycatch of demersal groundfishes, and eulachon, and minimize disturbance rates of benthic macroinvertebrates. Collaborators: PSMFC, ODFW, NWFSC MHE, and F/V Kylie Lynn.

Fishermen´s Loaner Video Camera System Program
Autonomous underwater video camera systems for fishermen to borrow for their use in evaluating industry-designed bycatch reduction devices. Collaborators: PSMFC, NWFSC MHE, and fishing industry.
