  • Description:
    "This document provides programs for estimating three measures of recreational effort using the Marine Recreational Fisheries Statistics Survey (MRFSS) data set. The programs produce estimates of target effort, catch effort and directed effort associated with a spcific fish species or species complex. A target trip is defined as a single angler trip on which the angler indicated the species was either the primary or secondary target species. A catch trip is defined as a single angler trip on which the species was caught regardless od target intention or disposition of catch (whether the fish was kept or released). A directed effort trip is defined as a single angler trip on which the species was either targeted or caught. The programs produce results consistent with expectations: catch effort exceeds effort and directed effort exceeds catch and target effort taken separately. This information can be used to evaluate trends in fishing effort and aid in estimating the potential impacts of regulation. Users of these programs are advised, however, to use caution with regard to species selection, degree of stratification and application of results. Although the MRFSS performs well at measuring activity for commonly caught species, it is designed to measre gross finfish activity and not activity in a specific fishery"--Executive summary.
