    Dusky Flathead as a Sports Species

    Dusky Flathead are prized by Sportsfishers because they are an agressive species that respond to a wide variety of lures. Other species provide greater challenge, thus sportfishers tend to invest more time in the other species but when conditions are not ideal or a feed is desired, Flathead is an attractive option.

    • Local Sportfishers reported a catch rate of 1.6 fish/fisher/day in 2016
