Title: AFSC/REFM: Pacific cod Localized Depletion Study
Short Name: AFSC/REFM: Pacific cod Localized Depletion Study
Status: Completed
Publication Date: 2016
Abstract:

Data from Localized Depletion study for Pacific cod 2001-2005. Study was conducted using cod pot gear to measure localized abundance of Pacific cod inside and outside of a trawl exclusion zone in the southeast Bering Sea, both before and after the intensive winter season cod trawl fishery. Data includes early feasibility and gear trials as well as before and after data from each of three years of the experiment. Pot gear was fished in 40 fixed stations in two adjacent areas, one of which was subject to heavy trawling and one within a trawl exclusion zone. Average of three or more pot catches at each station for each time period (before/after) was computed, the variable for final analysis was the change in catch at each station between the two periods. There are three main data tables. Cruise data identifies the dates, vessels, and personnel for each charter. Haul data includes information on location, date, soak time, and identifier for each pot launched, while Catch data includes numbers and weight of cod and bycatch by pot. Assorted small tables define categories for descriptive variables in main tables. Length and maturity data were collected on a random subset of cod catch. Some CTD profiles and oceanographic data were also collected.

Purpose:

Goals: 1) Development of research pot fishing gear for studying Pacific cod. 2) Evaluation of the effect of commercial fishing on local abundance of Pacific cod in the vicinity of a Steller Sea Lion haulout, to determine if intense local fishing reduces prey availability for the endangered mammal.

Data Quality

Completeness Report:

Not applicable.

Conceptual Consistency:

Catch data entered and proofed while at sea; binders hold raw datasheets and printouts of proofed data for each cruise day. All raw data files from wheelhouse, polycorder, etc. copied to central data computer and checked at sea, with daily backup. Polycorder downloaded and checked before data deleted. Haul, catch, and length data imported into spreadsheet format and checked for completeness. Post-cruise all data copied to network; spreadsheet files organized and subjected to preliminary analysis and QC. Spreadsheets from different cruises combined into master spreadsheet and Access database; some descriptive fields added.

Quality Control Procedures Employed:
