It was observed that river margins, key-areas for giant river otters, are being converted into annual crops (locally known as roças), contributing to change the availability of areas once used as dens, campsites or resting sites by the animals (see LIMA et al., 2012). They live in nests called holts. Revue d´Ecologie: La Terre et la Vie, Paris, n. 34, p. 495-620, 1980. A direct search for residents with information on negative interactions with giant river otters was also carried out. Based on the information provided by our co-investigators, the residents that interacted negatively with giant river otters were contacted and encouraged to report their experiences. The difference between those types of fisheries may lie in the frequency of occurrence and the extension of the nets used, but both should be considered in the identification of threats to giant river otters.

This study points out that the recent reoccupation of the Amanã Lake by giant river otters (see LIMA et al., 2014), a historical area of occurrence of this species in Amazonia, was followed by an increase in negative interactions between these animals and humans that live in the area. 4th ed.

Mammals using inland and coastal waters frequently interact with humans, as they often share habitats and explore similar resources (REEVES et al., 2002). Measures for the prevention and control of these threats must be included in the management plan of the Amanã Reserve. The rate of destruction of oxbow lakes will be curtailed and some otter populations outside protected areas will be safeguarded from mining and other human disturbance. The piscivorous habits of giant otters lead to negative human perception and conflicts with fisheries. However, it is necessary to consider the disperse use of habitats by otters, mobility of groups, and rarity of direct sightings, even during the dry season in the region.
