Grass Emperor are a popular food species and are the most commonly targeted inshore species.

  • 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

    • Local Sportfishers reported catch rate was 1.5 fish/fisher/day in 2014. More current data is under review
    • 2017 Qld Fisheries Boat Ramp Surveys reported a Cath rate of 0.9 fish/fisher/day
    • Bundaberg ranked 10th in the state for Grass Emperor Catch Rates
    • A decrease in Commercial Catch Rates was reported, from 8.47 kg/day in 2016 to 7.74 kg/day in 2017


    Quality of the Fish

    • 2017 Qld Fisheries Boat Ramp Surveys reported an average length of 388mm
    • Bundaberg ranked 3rd in the State for size of Grass Emperor (based on Qld Fisheries Boat Ramp Surveys - based on min 100 fish reported)


    Community Attitudes

    • 59% of fish reported in 2017 were kept
    • 57% of fish reported in 2017 were caught by locals 
    • Bundaberg ranked 13th in the state for the number of Grass Emperor released in 2017


  • Assessment

    Moderate Take For Consumption Advised

     Grass Emperor are the fifth most targetted offshore species and overall a lower portion of the offshore catch.  Commercial fishing for Grass Emperor is limited.  Release rates for Grass Emperor are very low with only 40.9% released.  Limited catches make it difficult to assess stocks however some caution should be exercised given harvest levels.

  • Forecast


     Forecasting for Bundaberg will be completed and available for the 2018/19 financial year.

    • A catch rate of 0.9 fish/fisher/day was reported in 2017 Qld Fisheries Boast Ramp Surveys
    • An averagelength of 388mm was reported in 2017
    • 59% of fish reported in 2017 were kept
    • 57% of fish reported in 2017 were caught by locals
    • The peak periods for Grass Emperor catches in 2017, were during February and September

  • Sportfishers


    Grass Emperor are targeted by sportfishers for much the same reason as other groups - take home for a feed. As sportfishers practice catch and release for their key estuary targets, the offshore fishery represents the opportunity to bring back a feed of fish for the family.

  • Commercial Fishing

    Commercial Fishing Catch

The commercial catch of Grass Emperor in Bundaberg (see Area Fished section) contributed 3.77% to the statewide catch in 2017. Monitoring is ongoing in 2018.

    • Commercial Catch rate decreased from 8.47 kg/fisher/day in 2016 to 7.74 kg/fisher/day in 2017
    • The number of active licenses in 2017 was 14 with between 14 and 33 active over the past 10 years.
    • Commercial catch in 2017 was 0.41T, compared to 0.61T in 2016.

    Area Assessed

    School Mackerel are caught throughout the Bundaberg region. Commercially they are targetted in Grids U31 to Z31, V32 and X32 to Z32. W32 has been excluded from the analysis as it represents Fraser Island catch data.
