Fishing has been my only profession, having spent 30 years in the commercial fishing industry and over 16 years as the owner/operator at Shark River Charters. If you enjoy catching fish, you'll love my charter. I like to go after Snappers and Groupers - you hold the fishing pole, feel the bite and reel em in. When not on the water you'll find Capt Dan in the Dakota's chasing birds with his Boykin Spaniel Kip

    It’s a good life at Shark River Charters!!!!

    Half Day Trip – Morning • 2 adults

    Thoroughly enjoyed an afternoon spent with my wife Bonnie, Captain Dan, and First Mate Jamie fishing in the Keys. Great company and weather. Greeted at the dock by a manatee and several large tarpon feasting on the snapper scraps. Star of the day was Boo Boo (ref. Yogi the Bear 😂), Jamie’s Maltipoo, a real sea dawg and cute as they come. Enjoyed Bonnie’s fresh caught mangrove snapper with huachaningo ala veracruzana sauce following the trip. Five Stars all around!

    Fantastic experience!

    Half Day Trip – Morning • 4 adults

    Captain Dan was excellent and the day was top notch. We caught all we wanted and it was quiet and relaxed and conversation was great. He cleaned and filleted our snapper and even recommended we take them to Frank’s in Marathon to have them cooked. We did and it capped off an already amazing day!

    Reported catch:
    Mangrove Snapper

    Great day on the water!

    3/4 Day Trip • 2 adults

    Capt Dan was great. He’s very experienced, knowledgeable, and friendly. He put us in the right spot to limit out on yellow tail and grouper. Follow his advice and you’ll have your best chance at catching the most fish. He took care of everything, all we had to do was show up and fish. Highly recommend him.

    Reported catch:
    Black Grouper

    captain Dan has a lot of experience and showed us how to fish for various types of fish ! The finale at his house with him fileting the catch is also a very cool time !

    Dan did a great job of getting us on the fish and helping us have a really good time. We fished for a half a day on the Gulf and got our limit of mangrove snappers. I would definitely recommend him to anyone.

    Determined to find the fish, Dan knew his spots so if one was slow he had a great backup so our experience catching could continue. We caught some great Red Snapper which we took to local restaurants to feast on for lunch and dinner.

    We had a great day with Captain Dan. At first the trip was canceled due to the possibility of bad weather. But, after an updated weather forecast, we trudged forward. While we didn't have great luck catching keeper fish, we had a fabulous day with Captain Dan. He taught us about fishing that only an experienced fisherman knew about. He took his time teaching my teenage son and daughter Riverhow to fish. I highly recommend Shark Charters.

What's biting with Shark River Charters in Marathon

Permit, Pompano, and Speckled Trout all arrive just as the Snook and Tarpon leave (the world's nice like that sometimes). Jacks join the regular crowd of Snapper and Grouper on the reefs, and there are still Tuna offshore.
