Catching a dorado fish, also known as mahi-mahi or dolphinfish, can be an exciting experience. Dorado are known for their vibrant colors, acrobatic jumps, and delicious taste. Here are some general tips on how to catch dorado:

1. Location: Dorado are often found in warm oceanic waters, particularly around floating debris, weed lines, and current edges. Look for areas with a combination of these features, as they attract baitfish and, in turn, dorado.
2. Bait: Dorado are opportunistic feeders and will go after a variety of bait. Common choices include live or rigged ballyhoo, mullet, squid, and small tuna. They are also known to hit artificial lures such as plastic skirts, feathers, and trolling lures.
3. Trolling: Dorado are often caught while trolling. Use a trolling spread with a mix of lures and baits at different depths and distances from the boat. Keep your speed between 5 to 10 knots, adjusting as needed based on conditions.
4. Colorful Lures: Dorado are attracted to bright colors. Use lures and baits in shades of green, yellow, blue, and pink. Adding a bit of flash to your setup can also increase your chances of attracting dorado.
5. Chumming: If you spot dorado around floating debris, you can increase your chances by using a bit of chum. Tossing small pieces of bait into the water can attract dorado to your location.
6. Gear: Use medium to heavy tackle with a strong, flexible rod and a reel with a smooth drag. Dorado are known for their acrobatics, so be prepared for energetic fights.
7. Be Ready for Action: Dorado can be aggressive and may strike suddenly. Keep a close eye on your baits and be ready to react when a dorado hits. They are known for their aerial displays, so prepare for jumps and runs.
8. Handling: Once you’ve successfully hooked a dorado, be cautious when bringing it onboard. They are known for their dazzling colors and can be quite powerful even out of the water. Use a gaff or a landing net to secure the fish.

Remember to check and adhere to local fishing regulations and guidelines, and practice responsible and sustainable fishing techniques. Additionally, local knowledge from experienced anglers or fishing guides in the area can be invaluable for a successful dorado fishing trip.
