Otters are regarded as pest by fish farmers in West Sumatra, Indonesia. However, the data on otter-fish farmer conflicts are not yet scientifically gathered. In this study we gathered the data on the conflicts which deemed important for formulating the conservation actions. We prepared questionnaires for the field staffs in the fisheries office in Padang Pariaman Regency, who supervise around 100 groups of fish farmers. We inquired the field staffs to apply the questionnaire during their visits at each group. Total 52 farmer groups returned the questionnaire. As many as 63.46% of the farmer groups’ fishponds ever visited by otters, where 18.18% of them visited within the previous month. Fish farmers commonly thought there were two otter species, yet they could not confidently identify which species they encountered. Otters visited fishponds from afternoon to early morning, with most visitations happened during midnight. Fish farmers indicated that otters came to fishponds when rain condition in 68.42% occasions. As many as 21.15% fish farmers (11 groups) mentioned catching and killing as methods to mitigate the disturbance by otters. Upon killed, otter carcasses were disposed as redeemed worthless. Despite the common perception on otters was negative, the fish farmers are willing to learn any method for fish farming that economically benefit for human, yet ecologically friendly for otter. We discussed further potential methods to harmlessly protect fish ponds from otters.
