Automated sediment toxicity testing and biomonitoring has grown rapidly. This study tested the suitability of the marine amphipod Corophium volutator (Pallas, 1766) for sediment biomonitoring using the Multispecies Freshwater Biomonitor (MFB). Two experiments were undertaken to (1) characterize individual behaviors of C. volutator using the MFB and (2) examine behavioral changes in response to sediment spiked with the pesticide Bioban. Four behaviors were visually identified (walking, swimming, grooming and falling) and characterized in the MFB as different patterns of locomotor activity (0-2 Hz range). Ventilation was not visually observed but was detected by the MFB (2-8 Hz). No clear diel activity patterns were detected. The MFB detected an overall increase in C. volutator locomotor activity after Bioban addition to the sediments (56, 100, 121 mg kg(-1)). C. volutator was more active (both locomotion and ventilation) in the water column than the spiked sediment. C. volutator appears a sensitive and appropriate species for behavioral sediment toxicity assessment and biomonitoring.
自动化沉积物毒性测试和生物监测发展迅速。本研究使用多物种淡水生物监测仪（MFB）测试了海洋双壳类动物卷壳沙蚕（Corophium volutator，帕拉斯，1766年）用于沉积物生物监测的适用性。进行了两项实验，一是用MFB表征卷壳沙蚕的个体行为，二是检测其对添加了农药必螨丹的沉积物的行为变化。通过视觉识别出四种行为（行走、游泳、梳理和跌落），并在MFB中将其表征为不同模式的运动活动（0-2赫兹范围）。未通过视觉观察到通气，但MFB检测到了通气（2-8赫兹）。未检测到明显的昼夜活动模式。MFB检测到在必螨丹添加到沉积物（56、100、121毫克/千克）后卷壳沙蚕的运动活动总体增加。卷壳沙蚕在水柱中比添加了药剂的沉积物中更活跃（在运动和通气方面均如此）。卷壳沙蚕似乎是用于行为沉积物毒性评估和生物监测的敏感且合适的物种。
