Статья. Опубликована в журнале Aquatic Ecosystem Health and Management, 2001, No02 p. 203-208 The medicinal leech (Hirudo medicinalis) is sensitive to various environmental changes. However, ecotoxicological investigations on these leeches are restricted because of their scarcity in natural waters. Artificial breeding of leeches makes possible the use of these animals in laboratory research. The aim of the present study was to investigate changes of feeding behaviour and excretion rate following feeding in medicinal leeches exposed to different samples of water from Lake Drukshiai which provides the cooling waters for the Ignalina Nuclear Power Plant (NPP). The following behavioural and physiological responses of medicinal leech exposed to waters of the Ignalina Nuclear Power Plant sampled in May and July 1997 were recorded: 1) feeding behaviour, that is, prolongation of the attachment process or a completely suppressed attachment reflex; 2) the size of blood meal; 3) excretion rate after feeding. The most harmful changes of indices under study were caused by water from industrial - rain sewage: the highest percent of individuals with prolonged attachment process or completely supp
