Stay safe & legal
Safety, rules and taking care of the fishery.
- Safety warnings
Slippery boulders and fast water — wear good wading boots and never wade alone.
- Regulations
Local rules vary; protected areas may close rivers. Each country sets its own license rules: Costa Rica requires a fishing license (INCOPESCA) for sea and fresh water, and Nicaragua, Honduras, Guatemala, Mexico and the Caribbean islands have their own rules. National parks and reserves often have special limits — check local rules before you fish.
- Conservation
Dams and river pollution threaten local populations.
