    Crystal Bowl GBR is aiming to examine 3 core measures across a wide range of species in the region:

    • Fishing experience (how many fish per trip)
    • Quality of the fish (size of fish)
    • Community attitudes (number of legal size fish kept or released)


    Fishing Experience

    • Qld Fisheries Boat Ramp Surveys report a catch rate of 1.23 fish/fisher/day
    • Weipa ranked 8th in the state for Grass Emperor Catch Rates in 2017
    • Not targeted commercially


    Quality of the Fish

    • 2017 Qld Fisheries Boat Ramp Surveys report an average size of 383mm in 2017
    • Weipa ranked 4th in the State for size of Grass Emperor (based on Qld Fisheries Boat Ramp Surveys - based on min 100 fish reported)


    Community Attitudes

    • 59% of Grass Emperor reported in Qld Fisheries Boat Ramp Surveys were released
    • 75% of fish reported in 2017 were reported by locals
    • Weipa ranked 11th in the state for the number of fish released

    • Fishers reported a catch rate of 1.23 fish/fisher/day in 2017

  • Sportfishers

    Local Sportfishers

    Grass Emperor are targeted by sportfishers for much the same reason as other groups - take home for a feed. As sportfishers practice catch and release for their key estuary targets, the offshore fishery represents the opportunity to bring back a feed of fish for the family.
