The Potential of Artemia-mediated Delivery of a Gonadotropin- releasing Hormone Analogue to Induce Ovulation in the Cardinal Tetra (Paracheirodon Axelrodi)

Artemia-mediated delivery of a gonadotropin- releasing hormone analogue (GnRHa) to broodstock cardinal tetras showed the potential to induce ovulation, as assessed by manual stripping. Exposure of the Artemia to the GnRHa for between 30 and 60 min was optimal for inducing ovulation while shorter and longer periods showed a trend to a decreasing percentage of ovulating fish. Further research on this method is warranted as the method could be applied to other fish species.
