    What's working on Grand Isle / Barataria Bay

    1. 01Redfish are actively feeding in shallower waters and along marsh edges as temperatures cool.
    2. 02Flounder are ambushing prey from the bottom, responding well to slow retrieves of crustacean and baitfish imitations.
    3. 03Shrimp and baitfish imitations are proving highly effective due to prevailing forage in the bay.
    4. 04While the main Tarpon migration is winding down, resident fish may still be present in warmer pockets, offering opportunistic chances.
    5. 05Topwater action for Redfish can be good, particularly during early mornings and late evenings.

    Merkin Crab

    #14#16

    Crabs are a consistent food source on the flats and inshore. This imitation is effective for tailing Redfish and Flounder actively foraging on the bottom.

    popper

    Gurgler (Saltwater)

    Baitfish/surface prey
    #1/0#2/0

    Topwater action can still be productive in the fall, especially during calmer mornings and evenings. This popper creates an enticing surface disturbance, drawing aggressive strikes from Redfish and potentially juvenile Tarpon.
