I was in southwest Nicaragua (Popoyo) this past July on a surf trip but I fished from shore one day and a couple days off a skiff. From the skiff I caught a couple YFT, a sailfish, Jack Crevall, Sierra, and Dogtooth Snappers eventhough the conditions weren't ideal at the time. From shore I caught leopard grouper, red snapper and a couple other species. Inshore there is suppose to be a lot of Roosterfish and offshore there is some big Wahoo.
The place is freakin Amazing for both surfing and fishing with little fishing pressure.
These guys at Surfari Charters have this place wired. I didn't stay with them but our skiff was next to theirs in the lagoon......saw them with a huge speared wahoo and dogtooth snapper.
