Sea cucumbers are easily fished in shallow waters around the world, which are processed to dried ones, and their prices are very high; therefore, exploitation has often been excessive. Overfishing has led to local depletion in some places. Several procedures such as stock management and restocking using hatchery-produced juveniles(seeds)are prompted to recover sea cucumber stocks. Such attempts should be carried out with knowledge not only applied sciences of fisheries biology but also related basic sciences such as ecology, physiology and genetics. In this paper, some examples are shown in aquaculture and resource management such as hormonal inducer of spawning used in hatcheries, DNA markers to detect hatchery-produced sea cucumbers, and appropriate regulation of fishing months using ecological information of seasonal distribution patterns and reproductive seasons. Both applied and basic sciences would be useful to develop solutions for aquaculture and fishery resource management.
