Volume 7 Pages 1 - 43 (February 1992) Vangla Nagulu Dept of Zoology, Osmania University, Hyderabad, 500 007 India Field study of river otters A project entitled "Studies on distribution status and ecology
of the river otter for their conservation in three ecologically
different habitats in the eastern Ghats area" was sanctioned by
Dept of Environment, Govt. of India and was put into operation during
January 1991. Two ecologically distinct study areas (a fresh water
river, Tungabhadra) in A.P. Karnataka border, and the other at Coringa
estuary, have been selected. Two investigators one research associate,
research scholar and a fieldsman are on the job. Otter enclosure at Nehru Zoo A new otter enclosure has been built at Nehru Zoological Park, Hyderabad. The enclosure has been built along the lines of those seen at the Otter Zentrum, Hankensbüttel, Germany. It is roughly circular, open, and constructed around a mound of boulders with water between land and viewers. The viewer side is sealed with a wide glass pane to minimise disturbance. An otter (Lutra perspicillata) was seen resting at the entrance of a hole under a boulder when the zoo was visited at midday. It seems that the present enclosure is better placed than the previous one, where visitors could go around the entire enclosure leaving no privacy for the otters. The two animals that were in the old enclosure used to be on the run all day, and eventually died one after the other. |
