| Abstract | ||||
| The rapid expansion of intensive sea cucumber farming makes it necessary to optimize the culture procedures to maximize the production in a profitable economic method. In this study, the effects of feeding rhythms and two stocking densities on the growth of sea cucumber Holothuria scabra were examined under controlled conditions. Specific growth rate, total weight increment, weight gain day-1 were determined for the sea cucumber fed in day-time; night-time and on two stocking densities (10 and 20 juveniles m-2). The impact of the feeding rhythm and stocking density on sediment quality was also evaluated. The feeding regimes did not affect the growth performance of sea cucumber, although the night feeding showed faster growth and the highest specific growth rate and daily weight gain when compared to the day-time feeding. Stocking densities tested showed a decrease in specific growth rate with the increase of stocking density, although it was not significant. In conclusion, this study showed that stocking of sea cucumber juveniles up to 20 individuals m-2 is viable for farming under supplemental feed. | ||||
