GLADSTONE SPANISH MACKEREL 2018

Spanish Mackerel are a popular food species due to their size and the ability to create fish steaks.

  • 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 0.2 fish/fisher/day in 2017
    • Gladstone ranked 6th in the state for Spanish Mackerel Catch Rates
    • Sportfishers reported a catch rate of 0.23 fish/fisher/day in 2017
    • Commercial Catch rate increased in 2017 (56.9kg/fisher/day) from 6.6kg/fisher/day in 2016

     

    Quality of the Fish

    • 2017 Qld Fisheries Boat Ramp Surveys reported an average length of 664mm in 2017
    • Gladstone ranked 5th in the State for the average length of Spanish Mackerel however, due to the small sample size, this ranking is unreliable
    • Commercial catch in 2017 was 16.5T, compared to 13.4T in 2016

     

    Community Attitudes

    • 64% of legal size fish reported by recreational fishers in the 2017 Qld Fisheries Boat Ramp Surveys were kept
    • 92% of fish reported in 2017 were caught by locals
    • Gladstone 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.
