Allometric relationships for species captured in longline fisheries from the western north Atlantic

Le résumé fourni par la source

Commercial landings data provide the platform upon which most research, assessments, and management plans are based. Data collection authorities obtain information from commercial records; however, commercial records are often in native units that are of limited use for data analysis. Conversion factors are used to convert landed condition weight or landed units of commercial seafood products to whole weight. Although many fisheries land product in whole form which does not require conversion, others record product in gutted, headed, carcass, fillet, tail, loins, fins or some other partial form of the fish. Conversion factors are also necessary for product landed in units other than weight in pounds, such as number, thousands, bushels or dozens. In addition, shellfish and crustacean fisheries generally land product as bushels, bags, baskets, numbers, shell on, shell off, or meat only. Conversion factors are then applied to these landed conditions or units with the resulting output of whole weight in pounds.
