ABSTRACT

The Neotropical otter (*Lontra longicaudis*) is an aquatic carnivore that
interacts with fisheries activities and competes with fisherman for
resources. Information about the biology and conservation issues of a
species can be obtained from traditional ecological knowledge collected
from the communities that share the same resources. In this sense, the
objective of this study was to describe conflicts between the otters and
two fishing communities (Imbé and Tramandaí) in the Tramandaí Lagoon
(29°57′S; 50°11′W), in southern Brazil. We conducted 36 interviews that
represented 72% of the local fishermen that use gillnets in the lagoon. All
fishermen reported that otters interfered with fishing activities, by
feeding on fish in the gillnets, and 75% of those interviewed reported gear
damage. Fifty percent of the fishermen reported that observed the otters
used the lagoon daily. Many fishermen (41.6%) also reported that the amount
of damage attributed to the otters was considered “small”, but the
depredation was reported as occurring daily (55.5%). Fishermen from Imbé
have a more negative perception of the interaction with otters, probably
because they usually fish near to the area most frequently used by otters.
This amplifies the magnitude of the conflict and damage. In order to
minimize the depredation of fish by otters directly on the gillnets, we
suggested some measures to fishery management, as well as additional
studies about the potential prey overlap between the Neotropical otter and
the fishery.
