Length-Weight Relationships of 22 commercial fish from Margarita Island, Venezuela

Length-Weight Relationships (LWR) were calculated for 22 commercial fish species caught by the artisanal fishing fleet of Margarita Island, Venezuela. A total of 1610 specimens were analysed, distributed in the following species: Lagocephalus laevigatus, Sphyraena guachancho, S. barracuda, Lutjanus purpureus, L. analis, L. griseus, Rhomboplites aurorubens, Lachnolaimus maximus, Priacanthus arenatus, Scomberomorus cavalla, S. brasiliensis, Euthynnus alletteratus, Auxis thazard, Sarda sarda, Thunnus atlanticus, Rachycentron canadum, Caranx hippos, C. crysos, Selene setapinnis, Alectis ciliaris, Trachinotus carolinus and Elops saurus. These length-weight relationships can be used to improve fish statistics because of difficulty in obtaining weight of the fish in field.
