Title: Species Composition - Bycatch Reduction Engineering Research
Status: Completed
Abstract:

Through key regional collaborations with the Pacific States Marine Fisheries Commission, Oregon Department of Fish and Wildlife, Alaska Fisheries Science Center, and the fishing industry, the Marine Habitat Ecology Team at the NWFSC has been able to pursue a wide-ranging array of conservation engineering projects relevant to reducing bycatch in the west coast groundfish and ocean shrimp trawl fisheries. Examples of types of research projects pursued during any given year include: 1) Reducing Chinook salmon, eulachon, rockfish, and Pacific halibut bycatch in midwater and bottom trawl fisheries using Bycatch Reduction Devices (BRDs), 2) Examining selectivity characteristics of codends that differ in mesh size and configuration in bottom trawl fisheries, and 3) Testing other novel bycatch engineering modifications to mobile and fixed gears. Much of our current work has been in response to the fishing industries concerns over catches of overfished and rebuilding rockfishes and Pacific halibut allocated in the Pacific coast Groundfish Trawl Rationalization Catch Share Program. The trawl rationalization program, starting in January 2011, established formal Annual Catch Limits (ACLs) and individual catch share quotas. In addition to ACLs, fishing opportunities may also be limited by hard caps or IBQs for non-groundfish species (e.g., Chinook salmon, and Pacific halibut). Bycatch of overfished and prohibited species in the west coast groundfish trawl fishery has the potential to constrain the fishery such that a substantial portion of available harvest may be left in the ocean.

Data Quality

Quality Control Procedures Employed:

Manual review of data is performed as the data is captured. These data were collected and processed in accordance with established protocols and best practices under the direction of the projects Principal Investigator. Contact the dataset Data Manager for full QA/QC methodology.

Data Management

Have Resources for Management of these Data Been Identified?: No
Approximate Percentage of Budget for these Data Devoted to Data Management: 0
Do these Data Comply with the Data Access Directive?: No
Is Access to the Data Limited Based on an Approved Waiver?: No
If Distributor (Data Hosting Service) is Needed, Please Indicate: No
Approximate Delay Between Data Collection and Dissemination: 180
If Delay is Longer than Latency of Automated Processing, Indicate Under What Authority Data Access is Delayed:

The time required to perform quality control.

Actual or Planned Long-Term Data Archive Location: NCEI-MD
Approximate Delay Between Data Collection and Archiving: 365
How Will the Data Be Protected from Accidental or Malicious Modification or Deletion Prior to Receipt by the Archive?:

The Northwest Fisheries Science Center facilitates backup and recovery of all data and IT components which are managed by IT Operations through the capture of static (point-in-time) backup data to physical media. Once data is captured to physical media (every 1-3 days), a duplicate is made and routinely (weekly) transported to an offsite archive facility where it is maintained throughout the data's applicable life-cycle.
