| 中文摘要 | Self-pollutants of bivalve biodeposits and macroalgae detritus from the raft bivalve-macroalgae polyculture may lead to increased organic matter in sediment; the deposit-feeding holothurians can effectively scavenge such particulate wastes and plays an ecological role of bioremediation. In the present study, a diet containing 75% biodeposits and 25% powdered algae was prepared to simulate the common mixture of the organic self-pollutant from the bivalve-macroalgae culture system. Furthermore, carbon and nitrogen budgets of the sea cucumber Apostichopus japonicus fed on the diet were modeled at six seawater temperatures (5, 10, 15, 20, 25 and 30 degrees C), and the influence of temperatures on the scavenging efficiencies for carbon and nitrogen (SEC, SEN) were assessed. The results showed that the temperature had a significant impact on the physio-ecological parameters (rates of ingestion, defecation, growth, respiration and excretion) and further affected the carbon and nitrogen budgets. The established budgets (except 30 degrees C) showed that the carbon loss in feces accounted for the majority of the ingested carbon (61.9-73.2%), and the nitrogen loss in feces and in excretion had similar percentages (42.6-83.6% and 42.9-61.2%, respectively). Meanwhile, the percentage of the ingested carbon or nitrogen allocated to growth increased, but that allocated to respiration carbon or excretion nitrogen decreased, with temperatures increasing from 5 degrees C to 15 degrees C; by contrast, the allocation patterns was exact opposite from 15 degrees C to 25 degrees C. At 30 degrees C, no carbon or nitrogen was ingested or defecated due to aestivation. The SEC and SEN at different temperatures were 0.0-38.5 mg C g(-1) d(-1) and 0.0-6.7 mg N g(-1) d(-1), respectively. A trend was observed that SEC and SEN peaked at 15 degrees C and decreased above and below this temperature; moreover, the SEC and SEN decreased to zero when temperature increased to 30 degrees C. Our study suggests that the scavenging capacity of A. japonicus on the organic pollutant from the raft polyculture is greatly influenced by the ambient water temperature, and the regression equations between SEC or SEN and the temperature (T) yield as SEC = 0.7639 T-3 - 11.886 T-2 + 48.745 T - 30.316 and SEN = 0.2324 T-3 - 3.0212 T-2 + 10.869 T - 6.760.
