Redthroat Emperor are a popular food species and are a commonly targeted offshore species. Most of the offshore activity for reef species around Hinchinbrook is conducted by recreational fishers.

  • Overview


    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

    • In 2017 Sportfishers reported a catch rate of 4 fish/fisher/day 
    • Qld Fisheries Boat Ramp Surveys reported a catch rate of 1.07 fish/fisher/day in 2017
    • Hinchinbrook ranked 9th in the state for Redthroat Emperor Catch Rates
    • An increase in Commercial Catch Rates, from 11.9kg/day (2016) to 33.1kg/day (2017) was reported


    Quality of the Fish

    • 2017 Qld Fisheries Boat Ramp Surveys reported an average length of 431mm in 2017
    • Hinchinbrook ranked 4th in the State for size of Redthroat Emperor (based on Qld Fisheries Boat Ramp Surveys - based on min 100 fish reported)


    Community Attitudes

    • 61% of fish reported in 2017 were kept
    • Hinchinbrook ranked 11th in the state for the number of fish released
    • 71% of the total catch was reported by visitors


  • Assessment

    Moderate Take For Consumption/Visitor Surveys Advised

Obtaining more detail on how the visiting fishers view their fishing experience and how it impacts their decisions to stay in the region would be advised.

    Heavy harvesting of Redthroat Emporer is not recommended, but a moderate take for immediate consumption is unlikely to adversely affect stocks based on available data.

  • Forecast


    • Catch rates should continue to be similar in 2018 (0.8-1.2 Fish/Fisher/Trip)
    • Most legal fish will be in the range 380-500mm
    • Recruitment is unknown
