Yellowfin Tuna Fishing in Jaco, Costa Rica
Yellowfin tuna are a favorite offshore target for anglers visiting Jaco. Tuna trips are exciting because the crew often reads birds, bait, dolphins, surface activity and current movement to find the fish.
Best trip style: Full day offshore fishing.
Best for: guests who want hard-fighting offshore fish and a trip that may also create opportunities for mahi mahi or billfish.
Yellowfin Tuna Fishing Overview
Tuna fishing is active and condition-driven. The boat may cover water until signs appear, then move quickly toward birds, dolphins, bait or surface feeding activity. When tuna are feeding, the action can turn on fast.
Yellowfin tuna are strong fighters and can be excellent table fish. A full day gives more time and range, which is important because tuna schools can move quickly offshore.
How to Catch Yellowfin Tuna
Crews look for life: birds picking bait, dolphins traveling with tuna, surface boils, current seams and clean water edges. The approach may include trolling, running to activity or adjusting presentations once tuna are found.

- Searching bait schools
