Overview - Crystal Bowl Rated Premium Fishery
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)
- 2017 T20 Fishers (Sportfishers) catch rate 2 fish/fisher/day
- Qld Fisheries Boat Ramp Surveys reported a catch rate of 0.4 fish/fisher/day in 2017
- Rockhampton ranked 5th in the state for Barramundi catches based on Qld Fisheries Boat Ramp Surveys
Quality of the Fish
- 2019 T20 Fishers (Sportfishers) most commonly reported fish are in the 501-600mm size range (92 fish), followed by 74 fish in the 701-800 size range then 67 fish in the 601-700mm size range
- Average length of Barramundi reported in 2017 Qld Fisheries Boat Ramp Surveys was 758mm
- Rockhampton ranked 5th in the State for size of Barramundi (based on Qld Fisheries Boat Ramp Surveys - based on min 40 fish reported)
- 2017 Qld Fisheries Boat Ramp Surveys reported 79% of Barramundi caught were released
- Rockhampton was ranked 4th in the state in 2017 for the number of fish released
- 51% of fish reported in 2017 were caught by visitors
Limited Take For Consumption Advised
NOTE: Limited take means recommended no more than 2 fish between 60cm-1m.Full 2018 Barramundi Forecast
- There will be a reduction in the percentage of legal fish in the catch due to the size range of fish spilling from Awoonga in 2017 being predominantly 500-700mm
- Overall catch rate and catch rate for legal fish will remain steady but may increase if fish spill from Lake Awoonga again as is possible in early 2018 (Feb-Apr)
- Catch rates in the Boyne River likely to be higher than for remainder of Gladstone Harbour due to fish spilling from Lake Awoonga in 2017 with little evidence of these fish moving beyond the Boyne River
- Stock level to remain steady with natural and fishing mortality likely to be offset by additional fish spilling from Awoonga
- Commercial Barramundi catch data for 2017 is only available for Feb-Sep and that indicates catch and catch rates are within the forecast range
- Commercial catch and effort data will be updated when complete 2017 data are available
- Neutral to slightly La Niña conditions are forecast for the recruitment period (Jan-Apr) with an average wet season with neutral conditions for the remainder of the year
- Forecast for Gladstone catchments is a 50-60% chance of exceeding median rainfall from Feb-Apr and rainfall to date suggests that conditions may not be conducive to good recruitment (expected)
Heavy harvesting of Barramundi is not recommended. Natural recruitment of Barramundi in Gladstone is poor to moderate even in good conditions. Top up stocks from Awoonga maintain stock levels but this population is vulnerable to localizedstock reduction if Awoonga dam levels drop.
Barramundi as a Sports Species
Barramundi are most commonly targetted by Sportfishers in Rockhampton.
- Local Sporftishers reported a catch rate of 1.5 fish/fisher/day in 2017 and 2 fish/fisher/day in 2018, so far

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 Bream in Rockhampton ends in 2015 with 2016 seeing the establishment of the net free zone at the mouth of the Fitzroy River (refer to Fishing Area section).
Charter Fishing Catch
Queensland Fisheries monitors charter catches up and down the coast. LImited data is available on Commercial Charter of Barramundi, with only 5 licences logging 45 active days for 0.02T of fish since 1997.
Monitoring of Barramundi Recruitment
Targeted Barramundi recruitment monitoring in Rockhampton commenced in 20** and will be ongoing. A summary of recruitment survey results is being drafted and will be made available when complete.
Monitoring of Barramundi
Data for this assessment has been sourced from:
- Bureau of Meteorology
- Queensland Fisheries
- Local Sportfishers and Suntaggers
- The Rocky Barra Bounty
Here are links to all the monitoring pages for Barramundi:
Barramundi are caught in the estuary, creek and nearshore areas of the Mackay region. Recreationally, they are targeted in inshore areas (map grids N24 and O24 to O26). Commercially, they are targeted in offshore area (map grids O24, O25 and O26 to X24, X25 and X26). It should be noted that grid N24covers most of the Mackay net free zone.
