摘要: Abstract During a survey in Albania we found signs of otters at 17 (54·8%) the 31 stations investigated. Otters were widespread much country, and healthy populations localised rivers marshes north-west south. Average sprainting activity was 1·7 positive sites per 200 m 3–6 spraints m. Frogs, probably Rana ridibunda , as well fish, appeared to be important prey for otters. In coastal plains, several grossly polluted growing agricultural industrial development may endanger survival
