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
- Qld Fisheries Boat Ramp Surveys reports catch rate of 1.25 fish/fisher/day
- Crimson Snapper were not commonly reported (18th most common at boat ramp surveys
- Slight decrease in Commercial Catch Rates, increasing from 5 kg/day (2015) to 2.3kg/day (2017 Incomplete)
Quality of the Fish
- 2017 Qld Fisheries Boat Ramp Surveys 482 mm
- Gladstone Ranked 5th in the State for size of Crimson Snapper but due to small sample size there is high uncertainty in that ranking.
- 75% of fish reported at Qld Fisheries Boat Ramp surveys are released
- Gladstone has the 5th highest rate of released fish in the state but due to small sample size there is high uncertainty in that ranking.
- 100% of fishers surveyed were local
Limited Take For Consumption Advised
Crimson Snapper are a small portion of the offshore catch for all species off Gladstone. Limited data makes full assessment difficult. Without clear evidence of stocks, some caution should be exercised on harvest.
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.
Heavy harvesting of Crimson Snapper is not recommended, but take for consumption is unlikely to adversely affect stocks based on available data.
- Catch rates will be in a similar range in 2018 (+20 - -20%)
- Average size of fish is likely to be similar in 2018 (Average 480mm)
- Recruitment is unknown
Capreef monitoring comprised surveys conducted between 2006-2009 on the local attitudes and experiences when it comes to the offshore fishing experience. The baseline established by Capreef provides context for assessments a decade later.
In examining the recreational catch over the past 3 years Longfin Rockcod was the most caught species (19%) while Coral Trout was the most likely species to be kept (85%) and Grass Emperor was the most numerous kept species. School Mackerel was the most caught species inshore, Longfin Rockcod around the islands, Hussar at the Wide Grounds and Redthroat Emperor on the offshore reefs.
Changes in size limits in 2004 have reduced the proportion of fish kept to less than 1% for Longfin Rockcod and 16% for Red Emperor while for Red Snapper and Redthroat Emperor over 55% are usually kept.Read the Capreef Report

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 Gladstone regularly report catching Crimson Snappr with most being returned to the water. Monitoring began in 2017 and continues in 2018.
- Crimson Snapper was not a commonly reported species, ranking 18th for Gladstone (40 fish)
- The average size of fish measured was 482mm
- Fishers reported an overall catch rate of 1.25 fish per day
- 75% of fish reported are released
- Peak period of April.
Gladstone Sportfishing lub
Crimson Snapper 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.
- Gladstone Sportfishing Club catch rate of TBA fish/fisher/day
- 2017 Gladstone Sportfishing Club average fish size was TBA mm
NOTE DATA IS STILL UNDER REVIEW AND UPDATES WILL BE AVAILABLE IN APRIL
A detailed snapshot of tagging by the Gladstone Sportfishing Club and Suntaggers is available:Gladstone Sportfishing Club Results
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 Crimson Snapper in Gladstone (S30,S31,T30,T31,U30,U31,V30,V31,W30,W31,X30,X31) represents 0.24% share of the total statewide catch. Monitoring is ongoing in 2018.
- Crimson Snapper are not a target species
- Commercial Catch rate is down from 5kg/fisher/day in 2015 to 2.73kg/fisher/day
- Number of active licenses has been ranged from 7-11 in the past decade.
- Commercial catch in 2017 is 0.03T (data incomplete), 0.07T in 2016.
Monitoring of Crimson Snapper Recruitment

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).
