从北大西洋东部在1981年和1978年，分别获得的照片和陷阱数据，已被合并到文件的响应深海lysianassid片脚类动物大的食物福尔斯，和捕食这些片脚类动物的鱼Paraliparis bathybius。使用新的照相机/海流计系统表明，端足类动物的总数和鱼类的存在与潮流有关。种的Parabellella和Orchomene是最丰富的端足类，并发生在低流速期间的峰值数量。Eurythenes gryllus，一个较大的物种，发生在较小的数量，丰富的变化，显然是不相关的潮流。深海副狮子鱼只在涨潮时出现。
Photographic and trap data obtained from the eastern North Atlantic Ocean in 1981 and 1978, respectively, have been combined to document the response of abyssal lysianassid amphipods to large food falls, and the predation on these amphipods by the fish Paraliparis bathybius. The use of a new camera/current meter system has demonstrated that overall numbers of amphipods and presence of fish were related to tidal currents. Species of Paralicella and Orchomene were the most abundant amphipods, and occurred in peak numbers during periods of low current velocity. Variation in abundance of Eurythenes gryllus, a larger species, which occurred in smaller numbers, was apparently not related to tidal currents. Paraliparis bathybius were present only during flood tides.
