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

    • 2017 Qld Fisheries Boat Ramp Surveys reported a catch rate of 0.2 fish/fisher/day
    • Karumba ranked 3rd in the state for King Threadfin Catch Rates


    Quality of the Fish

    • 2017 Qld Fisheries Boat Ramp Surveys reported an average length of 740mm in 2017
    • Karumba ranked 4th in the State for size of King Threadfin


    Community Attitudes

    • 60% of legal size fish reported by recreational fishers in the 2017 Qld Fisheries Boat Ramp Surveys were released
    • 79% of fish reported in 2017 were caught by visitors
    • Karumba ranked 6th in the state for the number of fish released
  • 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.

    King Threadfin as a Sports Species

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

    • A catch rate of 1 fish/fisher/day was reported for King Threadfin in 2016. No King Threadfin have been reported in 2018 so far
    • The catch mix in 2016 comprised 100% undersized fish, noting that only 2 fish were reported in 2016
    • Both King Threadfin reported in 2016 were in the 501-600mm 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 Karumba (see Area Fished sections) represented 28% share of the total statewide catch in 2017. Monitoring is ongoing in 2018.

    • Commercial Catch rates reported in 2016 and 2017 were 51.8kg/fisher/day and 58.2kg/fisher/day, respectively
    • The number of active licenses has ranged between 36 and 53 over the past 10 years with 36 active in 2017
    • The Commercial Catch in 2017 was 94.3T, compared to 62.3T in 2016
