Title: AFSC/FMA/NPRB Halibut Bycatch Video Field Test
Short Name: AFSC/FMA/Halibut Bycatch Video Field Test

Abstract:

These data arise from a field test of electronic monitoring (EM) of vessels participating in the Pacific halibut fishery off Alaska. A side-by-side comparison was made of the hook-specific catch data reocrded by fishery observers and EM video reviewers.

There are two main components of this data: the data collected by observers and the data recorded by video reviewers (electronic monitoring). The observer data are stored in an oracle database. The hook-specific EM data have been matched to the obsever data (individual hook to individual hook) and are stored in an MS Access Database.

Purpose:

The goal of this project was to test the ability of EM systems to operate in a commercial setting by comparing estimates of bycatch based on data collected by an observer with estimates of bycatch based on data collected using electronic monitoring (EM).

This data was collected to meet two main objectives. The first objective of this reseach were to collect catch and bycatch data collection commercial halibut fishery longline vessels using three data collection methods 1) using EM 2) using standard Alaska Fisheries Science Center Observer Program monitoring and 3) using hook-specific documentation of catch. The second objective was to evaluate the relative efficiency, cost, and bias of each of two bycatch estimation methods (EM, NMFS Observers) relative to a standard (hook-specific catch documentation) to determine their suitability for use in fisheries management.

Data Quality

Representativeness:

These data were subject to inseason review, and comprehensive debriefing. Data are subjected to automated error checking whenever changes are saved.

Accuracy:

There are multiple layers of error checking. Initial values include database check constraints. Once transmitted extensive automated error checking occurs and near real time data confirmation and/or corrections are communicated to the observers.

Bias:

Sampling bias due to the constraints of the physical environment is a known limitation, but does not appear to be significant over time.

Quality Control Procedures Employed:

These data were subject to inseason advising, automated error scripting, and comprehensive debriefing.
