 Marine shrimp are being cultured in Asia and Latin America, depending mostly on wild broodstock. Jorge A. Montoya explored advances in the controlled reproduction of these invertebrates. He carried out his research in Costa Rica, using different commercially important species. The topics evaluated were natural reproduction, in vitro fertilization, reproductive quality of males, induced maturation of females, and embryo/nauplii tolerance to cooling, cryoprotectans, and salinity. The findings of this research can be applied by the industry for a better management of the controlled reproduction of shrimp. It was found that sperm quality of pond grown shrimp can be improved by proper husbandry, and hormonal treatment. Jorge A. Montoya investigated a new technique to reproduce females in captivity without applying the common practice of cutting one of the eyestalks. The new procedure uses a neurotransmitter, serotonin, which is a promising alternative for the shrimp industry.
