Length-weight relationships of four finfish commercial species from the southern Gulf of Mexico

نویسندگان

چکیده

The relationship between total length and weight (LWR) of four commercial species finfish captured in the southern Gulf Mexico (Lachnolaimus maximus, Ocyurus chrysurus, Mycteroperca bonaci, microlepis) was estimated. Two these are region by small-scale fleet, while other two targeted semi-industrial fleets using harpoons, handlines, long-lines. For assessment, organisms were sampled at landing decks study area periods: 1996-1999 (semi-industrial fleet) from April 2017 to May 2018 (small-scale fleet). A 2780 individuals which 2775 used obtain LWR functions. showed negative allometric growth with b < 3 for 2017-2018 period, positive > period. This type information is an important input stock assessment that support fisheries zone under high fishing pressure levels.
