Abstract

This study aimed to establish a new nonlethal strategy to confirm the distribution range of Japanese water shrew. The survey was conducted in southern Nagano Prefecture during from September 2001 to November 2002 except for the December to March period. Distribution was judged by the feeding marks that remained in the containers in the survey period. Characteristics of feeding marks of water shrews are that the fish bait is halved without its backbone, or is pulled out of the container with visible feeding marks. The survey was affected by periods of interruption caused by rainfall, but was not affected by watercourse width. The survey period found to be sufficient to determine an absence of water shrew was 17 days.
