Plan by conditions

Ask what is biting before you book.

Capt. Troy builds the day around the season, wind, tide, water clarity and your crew. Redfish are the core target, but trout, black drum, flounder, sheepshead and seasonal nearshore fish can shape the plan.

Regulations can change. Always confirm current Louisiana Department of Wildlife and Fisheries rules before harvesting fish. Most charter guests age 18 or older should purchase the 3-day Charter Passenger Saltwater License; LDWF currently lists it at $20 for both residents and nonresidents.
