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

    • Qld Fisheries Boat Ramp Surveys reported a catch rate of 0.04 fish/fisher/day
    • Cairns ranked 7th in the state for King Threadfin Catch Rates
    • Sportfishers reported an increase in catch rate from 1 fish/fisher/day in 2017
    • A commercial catch rate of 56.6 kg/day was reported in 2017


    Quality of the Fish

    • 2017 Qld Fisheries Boat Ramp Surveys reported an average length of 664mm in 2017
    • Cairns ranked 9th in the State for size of King Threadfin however, due to only a single fish being reported, this ranking is unreliable
    • The total commercial catch in 2017 was 2.15T


    Community Attitudes

    • 55% of legal size fish reported by recreational fishers in the 2017 Qld Fisheries Boat Ramp Surveys were kept
    • Cairns ranked 8th 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.

    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. Fishers Cairns report catching King Threadfin with most being kept. Monitoring began in 2017 and continues in 2018.

    • King Threadfin were commonly reported in Cairns in 2017, ranking 31st
    • An average size of 664mm was reported by fishers in 2017
    • Fishers reported a catch rate of 0.04 fish/fisher/day in 2017
    • 55% of fish reported in 2017 were released
    • Peak period for King Threadfin catches in 2017 was during April

  • Sportfishers

    King Threadfin as a Sports Species

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

    • A catch rate of 1 fish/fisher/day was reported for King Threadfin in 2017
    • A single King Threadfin was reported in Cairns in 2017, which was 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. Data for the commercial catch of King Threadfin in Cairns is limited after the establishment of the net free zone at the mouth of Trinity Inlet in 2015 (refer to Fishing Area section).

    • A commercial catch rate of 56.6 kg/day was reported in 2017
    • The number of active licences has ranged between 6 and 12 over the last 10 years, with 6 active in 2017
    • The total catch in 2017 was 2.15T
    • The total catch in Cairns represented 0.6% of the statewide catchin 2017

    Importance of King Threadfin to Tourism

    Bream are not specifically a tourism drawcard but along with Whiting and Flathead, they are an important species for any family visitors. Family visitors are more likely to target species that are easier to locate in a short space of time.
