his study evaluated the utility of color pattern as a tool for sex identification inbroodstocks of Arapaima gigas. To do so, 110 individuals from three study sites had their sexdetermined with vitellogenin (VTG). Then, presence of red pigmentation was systematicallyevaluated scoring from the head (0) counting scales from the base of pectoral fin towards fishtail (1, 2, 3,...). Sex and study site were the variables that had significant effects on the zero-inflated negative binomial model (p<0.01) to assess color pattern. Discriminant functionanalysis (DFA) yielded 82 % of correct classification for females and 76 % for males. With suchmethod, both sexes could be identified with similar hit rates. Differences were seen in sexualcolor pattern comparing the different study sites. Therefore, application of the method should berestricted to site-specific broodstocks rather than be a general rule for all populations. Inconclusion, sex identification in Arapaima broodstocks through color pattern may be considereda cheap alternative for broodstock management but should be used in combination with otheravailable methods to yield optimal rates for sex identification (i.e. endoscopy, cannulationand/or vitellogenin). |
