Abstract

In an isolating experiment on feeding only on arthropods of terrestrial origin, the potential of their consumption by amphipods from a fishless watercourse has been studied. The data confirm the hypothesis that, on the basis of experiments on feeding exclusively on arthropods, it is possible to determine the maximum proportion of their biomass that the selected consumers are able to utilize. The results of such works can be used for a quantitative assessment of the level of possible losses of allochthonous matter and energy for the communities of recipient water bodies due to the feeding activity of consumers from their tributaries. Assessments of this kind may be relevant when making decisions on the food availability for juvenile Salmonids inhabiting recipient water bodies.

Gammarus koreanus Uéno（片足类）利用异地无脊椎动物的潜力

摘要

在一项仅以陆生节肢动物为食的隔离实验中，研究了来自无鱼水道的端足类动物消耗节肢动物的潜力。这些数据证实了这样的假设：根据仅以节肢动物为食的实验，可以确定所选消费者能够利用的最大生物量比例。这些工作的结果可用于定量评估受纳水体社区由于支流消费者的摄食活动可能造成的异地物质和能量损失的程度。在对居住在受纳水体中的幼鲑鱼的食物供应做出决定时，此类评估可能具有相关性。
