TOWNSVILLE GREY MACKEREL 2018

Grey Mackerel are a popular food species when in season.

  • Overview

    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 0.05 fish/fisher/day
    • Townsville ranked 3rd in the state for the catch rate of Grey Mackerel
    • Commercial Catch rate increased in 2017 (356.11 kg/fisher/day) from 261.85 kg/fisher/day in 2016

     

    Quality of the Fish

    • 2017 Qld Fisheries Boat Ramp Surveys reported an average length of 637mm in 2017
    • Townsville ranked 7th in the state for the average length of Grey Mackerel however, due to the small sample size, this ranking may be unreliable
    • Commercial catch in 2017 was 25.6T, compared to 17T in 2016

     

    Community Attitudes

    • 80% of fish reported in 2017 were released 
    • 86% of fish reported in 2017 were caught by locals 
    • Townsville ranked 3rd in the state for the release rate of fish
  • 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.
