A note on the growth of the juveniles of Holothuria scabra in concrete ring

Abstract

Although the seed of sea cucumber was produced more than sixty years back in Japan and China no serious attempts were made to farm them nor used the seed so produced to ranch and enrich the natural populations. Sea cucumbers are slow growing animals which live for a number of years. It Is expensive to maintain them for a longer period in the hatchery and therefore the seed Is sea ranched. Holothuria scabra reaches mEirketable size in 18 months and full size in two years time.
