Notes on Population Status and Feeding Behaviour of Asian Small-Clawed Otter (Aonyx cinereus) in the Sundarbans Mangrove Forest of Bangladesh
Pages 3 - 10 (Report)
M. Abdul Aziz

Very little information is available on population status, distribution and ecology of Asian Small-clawed Otter, Aonyx cinereus in Bangladesh. By surveying approximately 351 km of water courses in the Bangladesh Sundarbans, 53 individuals of this otter were recorded in 13 groups, with a mean group size of 4.08± SE 1.13. Mean encounter rate of combined sighting, footprint, and spraint was 0.06/km of rivers surveyed, with higher abundance along the eastern regions of the Sundarbans. Otters were found predominantly feeding on mudskippers (Periophthalmus sp.) on the exposed river mudflats, particularly during ebb tide. The chemical pollution in watercourses by several recent cargo incidents within the Bangladesh Sundarbans might have adversely affected otter populations. Systematic otter surveys are needed for a rigorous population assessment to guide conservation effort, and to monitor ecosystem health of the Sundarbans.

Photographic Documentation and Distribution of Smooth-Coated Otter (Lutrogale perspicillata) (Geoffroy 1826) in Surat, Gujarat
Pages 148 - 153 (Report)
Krunal Trivedi and Prashant Joshi

A group of Smooth-coated otter (Lutrogale perspicillata GEOFFROY 1826) was sighted at Gavier lake of Nature Club Surat. This group of otter was documented by Nature Club Surat with the help of camera traps. Nature Club Surat has also identified five other sites where indirect signs of otters were found. In March 2014 otters were sighted for the first time in Gavier Lake but no photographic evidences were found at that time. (http://timesofindia.indiatimes.com/city/surat/Endangered-otters-back-in-Gavier-lake/articleshowprint/31931076.cms?null). According to presently available data and information of Gujarat State Forest Department, smooth-coated otters are only found in Narmada River system and surrounding water sources such as wetlands, lakes, canals and streams.
