Species Overview
Blue Marlin
The blue marlin is the pinnacle of big-game fishing. Found in tropical and temperate Atlantic and Indo-Pacific waters, it can exceed 500 kg and is known for spectacular aerial displays when hooked.
Spotted Seatrout
The spotted seatrout, despite its name, is a member of the drum family, not the trout family. It inhabits grass flats and estuaries along the Atlantic and Gulf coasts. Males produce a distinctive drumming sound to attract females.
