Abstract
In six Caribbean wrasse (Labridae) species:Halichoeres bivittatus,Halichoeres garnoti,Halichoeres maculipinna,Halichoeres poeyi,Halichoeres radiatusandThalassoma bifasciatum, home range area (AHR) was positively correlated with fish total length (LT) and this relationship was not significantly different amongH. bivittatus,H. garnoti,H. radiatusandT. bifasciatum. The data for three of these species (H. radiatuswas excluded because only juveniles were investigated) were pooled and the relationship betweenLTandAHRwas analysed for juveniles and initial phase (IP) adults separately. This analysis found that once individuals of these two species become IP adults, theAHRreached a plateau, despite continued fish growth. In a separate analysis including all six wrasse species, after accounting for differences inLTusing ANOVA, it was found that IP adults required larger areas than juveniles, and terminal phase (TP) adults required largerAHRthan IP adults. Upon analysis of the distribution of activity throughoutAHRfor all species studied, it was found that 50% of the observation points (defined as the activity centre) were found in 13 to 24% of theAHR.
