英文摘要	the aim of this study is to investigate the potential of using marine sponge hymeniacidon perleve to remove total organic carbon (toc) in integrated aquaculture ecosystems. in sterilized natural seawater (snsw) with different concentrations of toc, h. perleve removed approximately 44-61% toc during 24 h, with retention rates of ca. 0.19-1.06 mg/h center dot g-fresh sponge, however no particulate selectivity was observed. the highest initial toc concentration, in which about 2.7 g fresh sponges could remove toc effectively in 0.5-1, snsw, is 214.3-256.9 mg/l. the highest capacity of toc removal and clearance rate (cr) by h. perleve is ca. 25.50 mg-toc/g-fresh sponge and 7.64 ml/h center dot g-fresh sponge within 24 h, respectively. until reaching the highest toc removal capacity, the toc removal capacity and clearance rate of h. perleve increased with initial toc concentration, and dropped dramatically thereafter. after reaching the highest removal capacity, h. perleve could only remove relatively lower toc concentration in seawater in subsequent run. the toc removal kinetics in snsw by h. perleve fitted very well with a s-shaped curve and a logistic model equation (r-2 = 0.999). in different volumes of snsw with a fixed initial toc concentration, the weight/volume ratio of sponge biomass and sfnsw was optimized at 1.46 g-fresh sponge/1-l snsw to achieve the maximum toc removal. when co-cultured with marine fish fugu rubripes for 15 days, h. perleve removed toc excreted by f. rubripes with similar retention rates of ca. 0. 15 mg/h center dot g-fresh sponge, and the sponge biomass increased by 22.8%.
