Bonaire is one of the best Bonefishing destinations in the world. This style of fishing is done under a local guide as it takes place within the marine park which is classified as private property. Bonefishing on Bonaire is also under a catch and release policy.
Bonaire, however, also offers excellent deep sea fishing. Catch your own Tuna or Wahoo. You will need to inquire with your fishing charter, but most fishing done by visitors also works with a catch and release policy, especially in the case of the Marlin Fish, in order to sustain the population of the fish. Some charters allow you to keep your catch but this would need to be discussed with the charter prior.
Visitors don't require a license for non-commercial fishing on Bonaire.
