Description |
In Dasyatis imbricatus only the ovary and the uterus on the left side are functional. It has a prolonged breeding season from December to July and produces 1 or 2 emibryos. The ova are ready for ovulation even before the parturition of the embryo in the uterus. The females reach maturity when they attain the size of 170-179 mm as confirmed by the ponderal index. The males in the 160-169inin size group are mature as judged by the relationship between body length and elasper length. S;xes in the commerical catches vary — 51.25% mles to 48.75% females |
