Documentation for NEFSC Electronic Monitoring API
NOAA Northeast Fisheries Science Center and Fisheries Greater Atlantic Regional Fisheries Office
Reference publication of spatially and temporally synoptic length-weight observations collected along the Northeast coast of the United States during the Northeast Fisheries Science Center’s (NEFSC’s) research vessel winter, spring, and autumn bottom trawl surveys from 1992 to 1999. Length-weight parameters were calculated for 74 fish species. Results from this study are the basis of length-weight conversion factors for Electronic Monitoring discard estimates. Video review software platforms shall utilize this reference when developing applications to populate weight estimates.
Wigley, et al. (2003) Length-weight relationships for 74 fish species collected during NEFSC research vessel bottom trawl surveys, 1992-99
Reference that adjusts for seasonality in weight conversion factors according to the Wigley et. al. paper. Video review software platforms shall use this reference for assignment of season by month for discard estimates.
