The ecology of the river otter living in Yakutia has not been studied enough. In this regard, an analysis was conducted of perennial field materials, literary sources on the ecology of this species. Field work was carried out from 1981 to 2012. South-Western (Lensky and Olekminsky districts) and South (Aldan, Ust-Maysky, Neryungri districts) of Yakutia. Departmental materials were used: the Yakutsk branch of the All-Union Scientific Research Institute of Hunting and Animal Farming, Sakhabult, Gosokhotokrran, questionnaires (156 hunters) and personal data (n = 248). Otter was taken into account when recording the number of sable. Eight otter carcasses were processed. The analysis of 413 excrement were processed. In Yakutia, otters are rare, distributed unevenly. The otter habitats in winter in the conditions of Yakutia are confined to rivers with relatively fast currents, where small rifts usually alternate with deep stretches and where there are ice-free areas located not very far from each other. In March 2005, when zmu was conducted in the Olekminsky district, otters lived on the r. Krestyakh (right tributary of the Olekma River), 56 km from the mouth, on the river. Pain. Chokur (right tributary of the Olekma River) and in the middle course of the Creek Pain. Dzhikimda (right tributary of the river Olekma). In July 2006, the otter's habitation was noted by us in the middle reaches of the river Maya (right tributary of the Aldan River) 260 km from Ust-Maya. In April 2010-2011 on Chabda River (left tributary of the Maya river) 100 km from the estuary, an otter habitat was found. Under the conditions of Yakutia, the otter does not live on lakes and in the channels of calmly flowing rivers. The diet of Yakut otter: this is the predominance of fish (76.8%).
