Redthroat Emperor are a popular food species and are a commonly targeted offshore species. Most of the offshore activity for reef species around Rockhampton is conducted by recreational fishers.

  • 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

    • In 2017 Sportfishers reported a catch rate of *** fish/fisher/day 
    • Qld Fisheries Boat Ramp Surveys reported a catch rate of 1 fish/fisher/day in 2017
    • Rockhampton ranked 10th in the state for Redthroat Emperor Catch Rates
    • An increase in Commercial Catch Rates, from 15.6 kg/day (2016) to 22.4 kg/day (2017)


    Quality of the Fish

    • 2017 Qld Fisheries Boat Ramp Surveys reported an average length of 418mm in 2017
    • Rockhampton ranked 6th in the State for size of Redthroat Emperor (based on Qld Fisheries Boat Ramp Surveys - based on min 100 fish reported)


    Community Attitudes

    • 68% of fish reported in 2017 were kept
    • 59% of fish reported were caught by visitors
    • Rockhampton ranked 12th in the state for the release rate of Redthroat Emperor in 2017


  • Forecast

    Moderate Take For Consumption Advised

    Redthroat Emperor catch rates are among the best for all species off Gladstone and there are no reported issues for the species. This however is relative to current effort. Maintianing the current community harvest attitudes to the species is appropriate to maintaining the health of catch rates over the longer term.

    It should be noted that the longest term dataset Yaralla Deep Sea Club indicates that long term catch rates can be variable ranging from 0.6 fish/fisher/day in 2013 to 6.2 in 2003.

    • Catch rates should continue to improve in 2018 (+10-+30%)
    • Average size of fish is likely to be similar in 2018 (Average 400mm)
    • Recruitment is unknown


    Heavy harvesting of Redthroat Emporer is not recommended, but a moderate take for consumption is unlikely to adversely affect stocks based on available data. 

    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 in Rockhampton regularly report catching Redthroat Emperor with most being kept for food. Monitoring began in 2017 and continues in 2018.

    • Redthroat Emperor was the 11th most commonly reported species in Rockhampton in 2017
    • The average size of fish measured in 2017 was 418mm
    • Recreational fishers reported a catch rate of 1 fish/fisher/day in 2017
    • 68% of fish reported in 2017 were kept
    • Peak periods of Redthroat Emperor catches in 2017 were during June and August

  • Sportfishers

    Redthroat Emperor

    Redthroat 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, offshore represents the opportunity to bring back a feed of fish for the family.

  • 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 Redthroat Emperor in Rockhampton (see Area Fished section) represented 4.94% share of the total statewide catch in 2017. Monitoring is ongoing in 2018.

    • Commercial Catch rate is up from 15.6 kg/fisher/day in 2016 to 22.4 kg/fisher/day in 2017
    • Number of active licenses has ranged between 21 and 37 over the last decade with 37 licences active in 2017.
    • Commercial catch in 2017 was 7.16T, compared to 4.38T in 2016.

  • Fishing Area

    Area Assessed

    Offshore catch monitoring is more difficult than inshore as each of the monitoring agencies define different boundaries around fishing areas. These boundaries can overlap with other regions.   Fishers from Gladstone for example fish offshore from Rockhampton. Commercially Grids included in the assessment: S30,S31,T30,T31,U30,U31,V30,V31,W30,W31,X30,X31 (Gladstone).
