King Threadfin are a popular target for sportfishers due to the level of skill required to be able to target them successfully and often.

  • 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

    • Commercial Catch rates increased in 2017 (42.3kg/fisher/day) from 32.7kg/fisher/day in 2016


    Quality of the Fish

    • The Commercial Catch in 2017 was 1.86T, compared to 1.57T in 2016

    Community Attitudes

    No reliable community attitude data is available for King Threadfin in the Whitsundays based on the limited number of fish reported 

  • Forecast

    Moderate Take For Consumption Advised

    • Boyne Tannum hookup catch rate between 1.2 and 1.6 fish/fisher/day
    • 95% of Yellowfin Bream in the Boyne Tannum Hookup will be between 270 and 290mm
    • Recruitment is likely to be moderate


    Heavy harvesting of Bream is not recommended, but a moderate take for consumption is unlikely to adversely affect stocks based on available data. Evidence from the Qld Fisheries boat ramp surveys suggests that most fish are released but with only a single year of data, this will need to be assessed as additional data is collected.

     NOTE: Moderate take means taking what is required for immediate needs.

    Monitoring of Recreational Catch by Qld Fisheries

    Queensland Fisheries monitors boat ramps up and down the coast as a part of the Sustainable Fisheries Strategy. No King Threadfin were reported in 2017. Monitoring continues in 2018.

    King Threadfin are a prized sports species in most locations across Queensland. In the Whitsundays, King Threadfin are targeted mostly by Sportfishers.

    • A catch rate of 2 fish/fisher/day was reported for King Threadfin in 2017. Monitoring is ongoing for 2018
    • The catch mix in 2017 comprised 100% legal sized fish
    • The most common King Threadfin size reported in 2017 were fish in the 801-900mm size range

  • Commercial Fishing

    Commercial Fishing Catch

    Queensland Fisheries monitors commercial catches up and down the coast. Commercial fishers are required to maintain logbooks of catch and report quarterly. The commercial catch of King Threadfin in the Whitsundays (see Area Fished sections) represented 0.55% share of the total statewide catch in 2017. Monitoring is ongoing in 2018.

    • Commercial Catch rates increased in 2017 (42.3kg/fisher/day) from 32.7kg/fisher/day in 2016
    • Ten licenses were active in 2017, with 8-15 active over the past 10 years
    • The Commercial Catch in 2017 was 1.86T, compared to 1.57T in 2016
