Behavior intention
About killing:
63%, would kill sea lions if it was not forbidden by the Brazilian law
About management:
91%, interest in attending public meetings
90%, find it important to be heard before any decision of management in the
region
88%, help decide on quotas and
fishing areas
Do they want to participate
in sea lion management, or
just to take advantage of
these meetings to discuss
fishing quotas for example?
Final Considerations
Dissatisfaction among fishermen regarding fishing in the
region associated with the sea lion.
Environmental education with children and adults in the community
