AbstractSea cucumber, Apostichopus japonicus, is the main cultured species in China. The main culture style for this species is the sea ranching model. Field trials were conducted in bottom-cages to preliminary reveal optimal releasing size, as well as maximum density of A. japonicus in an integrated multi-trophic aquaculture sea ranching area. Different sizes (4-30 g ind(-1)) and densities (336-1342 g m(-2)) of sea cucumbers were cultured for 13 months in Rongcheng Bay, Shandong Province, China. The size experiment showed that sea cucumber of all sizes grew throughout the experimental period. Sea cucumbers < 15 g had high mortality in summer and low SGR in winter, while larger individual (> 20 g ind(-1)) had no advantage of growth. Sea cucumber sizes of 15-20 g may be suitable for release, considering their higher survival rate and SGR. The density experiment showed that the high biomass group had a low SGR and that the maximum release biomass was 793 g m(-2) based on a regression analysis. The optimal practical release season for sea cucumber was spring based on the results of two field experiments.
