Larval development and juvenile growth of the sea cucumber Stichopus sp (Curry fish)

The global populations of Curry fish have been severely depleted over the past decade. This study describes spawning, fertilization, larval rearing, and juvenile growth in a commercially important Stichopus species. Data pooled from monthly trials conducted over 2 years indicate that, under optimal conditions, juveniles can be grown to a size of ca. 20 cm in length in 7 months. The survival rates are typically between 30 and 50%. Pilot research indicates that the growth of young sea cucumbers in abandoned abalone tanks has potential. Overall, this study demonstrates that Curry fish can be reared in captivity, thus providing an alternative to fisheries. or a way to maintain sustainable harvests and eventually contribute to the restoration of the natural populations.
