Growth parameters of the spiny lobster (Panulirus argus) in the Great Caribbean: a review
The aim of this review is to compare the growth parameters of the spiny lobster (Panulirus argus) in three fishery regions: Caribbean Sea, Northern and Brazil. A high variability in the estimates of L∞ and K has been observed in the studies of 42 growth parameters in ten locations. The mean size of L∞ by sex was significantly different between regions (P <0.05). However, there was no significantly different in parameter K between the sexes (P = 0.2015). The results of the nonparametric SNK test demonstrated that average L∞ (199.78 mm) of male were highly significant differences (P <0.05) of the average L∞ of females in the Caribbean (172.27 mm) and Brazil (142.42 mm) region. The average L∞ of Northern region (male and female), female of Caribbean and male of Brazil appear to have come from the same sample. This is perhaps not viable and the reason behind such conclusion is that the multiple range test was not able to determine differences accurately when samples are small (n=3). In Northern and Brazil, the occurrence to detect statistical differences between growths parameters was not possible and thus, we decide to calculate the von Bertalanffy growth curve for P. argus at this previous regions per sex.
