Crab Pot Escapement Study
More than 12,000 crab pots are lost and become derelict every year in Puget Sound, killing over 177,000 harvestable crabs and costing the fishery more than $700,000. The Northwest Straits Foundation works to eliminate impacts of lost crab pots through targeted removals, research, and prevention outreach and education.
One way to minimize harm from lost pots is to ensure that trapped crab can excape when the legally required biodegradable escape cord disintegrates. Unfortunately, our experience removing over 3,900 crab pots in Puget Sound shows that not all crab pot escapement mehcanisms effectively allow crab to escape, killing and estimated 12,000 to 30,000 crab annually.
The Crab Pot Escapement Study was designed to determine the effectiveness of commonly used recreational pot designs and test simple modifications to increase escapement effectiveness. The study determined the escapment rates of Dungeness crab from 13 different crab pot configurations used in the Puget Sound recreational crab fishery.

Derelict Gear Removal program receives Salish Sea Science Prize
Northwest Straits Foundation earned the Sea Doc Society's prestigious Salish Sea Science Prize at the Salish Sea Conference in Seattle on May 1. The prize was awarded in recognition of our work removing derelict gear from the Salish Sea and documenting the positive impact to marine animals and habitats of the Northwest region lf the Salish Sea.
The award was given by Dr Joe Gaydos, Director of SeaDoc Society. In his commendation for the Foundation's commitment to eliminating harm caused by derelict fishing gear in Puget Sound, Dr. Gaydos concluded that our work, "serves as an example to the world for how science is a crucial foundation for designing healthy ecosystems and drives ecosystem recovery."

About the Northwest Straits Marine Conservation Foundation
The Northwest Straits Foundation is the non-profit partner of the Northwest Straits Marine Conservation Intiative. The Foundation works to preserve and protect the marine resources of the Northwest Straits by supporting scientific, restoration, and education projects in collaboration with county Marine Resources Committees and the Northwest Straits Commision. The Foundation, Commission and the Marine Resources Committees collectively advance the work of the Northwest Straits Marine Conservation Initiative, a nationally recognized, innovative approach that brings sound science and an ecosystem perspective together with citizen energy and entrpreneurship to the challenge of marine conservation. Read more about the Foundation's collective impact on the Initiative's work, and read our 2014 Report to the Community here.Learn more about the Northwest Straits Commission, and the seven county Marine Resources Committees here.

Gear Removal to Date
As of June 30, 2015, the Northwest Straits Foundation has removed more than 5,660 derelict fishing nets and 3,800 shellfish pots from Puget Sound, restoring 813 acres of important marine habitat.
More than 466,000 animals, representing more than 260 unique species, were found entangled in this gear. Species found include porpoise, seals, sea lions, scoters, grebes, cormorants, canary rockfish, Chinook salmon, and Dungeness crab. For a complete report of our progress to date, click here. To view of map of the locations where nets have been removed click here.
Deepwater nets: We also know there are untold numbers of nets in deeper water, possibly entangling endangered rockfish and other deepwater species and destroying habitat. Three species of deepwater rockfish, Bocaccio, yelloweye, and canary, are listed under the federal Endangered Species Act. NOAA and Washington Department of Fish and Wildlife identify derelict fishing nets as a likely stressor on these rockfish and recommend the removal of derelict fishing nets to help recover the species. Deepwater derelict net removal is also a Near Term Action identified in the 2012 Puget Sound Action Agenda.
The Northwest Straits Foundation is actively removing derelict fishing nets from Puget Sound in waters to 105 feet, but currently does not operate below that depth due to diver safety concerns. A June 2013 report, Deepwater Derelict Fishing Gear Removal Protocols: Identifying and Assessing the Feasibility of Removal of Deepwater Derelict Fishing Nets from Puget Sound, Washington was commissioned by the National Oceanic and Atmospheric Administration (NOAA) Protected Species Program and explores various deepwater removal protocols, including the use of remotely operated vehicles (ROVs), grapples, and deepwater divers.
The most promising protocol identified in the report is the use of ROVs to remove deepwater derelict fishing nets. A pilot project to test this removal method in shallow water prior to testing in deeper water is recommended. Known nets in both shallow and deep water are identified for this pilot project. The Northwest Straits Foundation is currently seeking funding for this pilot project. The report was written by Natural Resources Consultants, the firm that manages the field work for the Northwest Straits Foundation’s derelict fishing gear program. Click here to view the full report.
Crab pots: Approximately 12,000 crab pots are lost and become derelict every year in Puget Sound, costing the fishery up to $700,000 in lost harvest revenue. Northwest Straits Foundation is working to address the problem of crab mortality in derelict crab pots, and to develop a strategic approach that reduces the negative impacts of crab pot loss. We support local outreach efforts to aimed at recreational crabbers to promote best crabbing practices. The Foundation recently completed a crab escapement study to investigate escapement rates of different styles of crab pot designs, to determine the most effective ones, and to use the research to promote best fishing practices to state and tribal crab fishery managers. We identified designs and low-cost modifications that are shown to be most successful at allowing crab escapement. Read more about our research and preliminary results of the crab escapement study in our March 2015 newsletter.
ARRA Project Complete
In 2010, the Foundation completed an 18-month project with $4.6 million dollars of economic stimulus funding from NOAA. The project enabled us to ramp up our removal operations from one boat operating part time to four full-time removal vessels. For more information, click here.

The Northwest Straits Initiative is committed to eliminating harm from derelict fishing gear in marine waters of Puget Sound.
What is derelict gear?
Derelict fishing gear includes fishing nets, lines, crab and shrimp traps or other equipment that is abandoned or lost in the marine environment. Such gear poses many problems to marine animals and people.
