Evaluation of Ovaprim and human chorionic gonadotropin doses on spawning induction and egg and larval quality of pinfish, Lagodon rhomboides

Doses of 0.25 and 0.50 mL/kg Ovaprim were efficient at induction of FOM and spawning in pinfish. Superior fecundity, fertilization and 3 day post hatch (DPH) survival rates, as well as larger 3 DPH larvae support lower Ovaprim doses as the preferred choice for use with this species. Conversely, the 4000 IU/kg HCG dose performed the best of all HCG doses evaluated eliciting the greatest spawning frequency from female pinfish.
