All LLRs (TL—FL, FL—SL, FL—TL, Gulf of Mexico (GOM), and the Caribbean Sea (Westneat and SL—TL) were estimated using linear regressions on 2002), where it has high economic importance (McBride and log10 data. The LWRs were calculated as log10W = log10 a + Murphy 2003) as a fishery resource. Off the Florida coast, b log10TL, where “a” is the intercept of the regression curve it reaches a maximum size of 84 cm fork length (FL) and a (coefficient related to body form) and “b” is the regression maximum body weight of 10 kg (McBride and Richardson coefficient (exponent indicating isometric growth) (Le Cren 2007). Due to heavy fishing pressure, there is evidence of an 1951, Froese 2006). Based on the slope (b) of the LWR, one overfished condition for L. maximus (McBride and Murphy can estimate whether fish growth is isometric (b = 3, all fish 2003, Ault et al. 2005) with population declines of 60%. dimensions increase at the same rate), hypoallometric (b < 3) Regionally, due to this condition it is classified as vulner- or hyperallometric (b > 3) (Froese 2006, Froese et al. 2011). able by the International Union for Conservation of Nature Exploring which growth (i.e., isometric or allometric) is ex- (Choat et al. 2010); thus, it is important to record as much hibited by a given species provides inference on how fish biological information as possible to understand its popula- body proportions may vary at a given geographic area or dur- tion dynamics in the region. ing a specific season.
