Abstract Integrated Multi-Trophic Aquaculture (IMTA) systems have been designed to optimize nutrient and energy use, to decrease waste, and to diversify fish-farm production. Recently, the development of detritivorous aquaculture has been encouraged, as detrivores can consume organic particulate matter, reducing benthic eutrophication and the environmental footprint of aquaculture. To this end, the polychaete Hediste diversicolor is a promising species due to its broad feeding behaviour and its resistance in a wide range of environments. In this study, an existing Dynamic Energy Budget (DEB) model of H. diversicolor was used to predict the ragworm's metabolic processes in various environmental conditions and to estimate its bioremediation capacity in an aquaculture context. First, the scaled functional response (f) was calibrated in a 98-day growth experiment with two types of food (Fish faeces and Fish feed). Then, we further validated the model using data on the ammonia excretion and oxygen consumption of individuals fed with fish faeces at four different temperatures using the previously calibrated f. Overall, we found that the DEB model was able to correctly predict the experimental data (0.51

使用动态能量收支理论评估多毛类 Hediste diversicolor 在综合多营养水产养殖系统中的生物修复潜力

摘要 综合多营养水产养殖 (IMTA) 系统旨在优化养分和能源使用，减少浪费，并使养鱼场生产多样化。最近，腐食性水产养殖的发展受到鼓励，因为腐食性动物可以消耗有机颗粒物，减少底栖富营养化和水产养殖的环境足迹。为此，多毛类 Hediste diversicolor 因其广泛的摄食行为和在广泛环境中的抵抗力而成为一种有前途的物种。在这项研究中，现有的杂色嗜热菌动态能量收支 (DEB) 模型用于预测各种环境条件下蛔虫的代谢过程，并估计其在水产养殖环境中的生物修复能力。第一的，缩放功能响应 (f) 在 98 天的生长实验中用两种食物（鱼粪和鱼饲料）校准。然后，我们使用先前校准的 f 使用四种不同温度下用鱼粪便喂养的个体的氨排泄和耗氧量数据进一步验证了该模型。总体而言，我们发现 DEB 模型能够正确预测实验数据（0.51
