Length-weight relationships for 73 species and species groups as reported in the 2011-2013 national bycatch reports for pelagic longline fisheries in Hawaii and American Samoa

  • Description:
    "This report provides summaries of length-weight relationships for pelagic species reported in the Hawaii and American Samoa based longline fisheries. NOAA periodically produces a National Bycatch Report (NBR) estimating total weight by species or species group for all species taken by these fisheries. Past reports have utilized both unpublished and published estimates of lengthweight relationships to apply an average weight for an individual of each species to the total number reported in a fishery. The data sources used to generate the length-weight regression coefficients necessary to convert average length of a species (from observer collected length frequency data) have not been well documented. This report provides documentation on the data sources, sample sizes, size ranges, and assumptions used to generate the length-to-weight conversion equations for each species/species group as reported in the NBR report for 2011- 2013 catch estimates. This report does not reflect any new regression analyses, it is an attempt at documentation of where the regression coefficients used in the NBR summaries originated"--Introduction [doi:10.7289/V5CF9N42 (http://dx.doi.org/10.7289/V5CF9N42)]
