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 (the number of fish kept or released)
- Qld Fisheries Boat Ramp Surveys reports catch rate of 1.2 fish/fisher/day in 2017
- Saddletail Snapper were a commonly reported (10th most common at boat ramp surveys)
- Increase in Commercial Catch Rates, increasing from 6.84 kg/day (2015) to 10.3kg/day (2017 Incomplete)
Quality of the Fish
- 2017 Qld Fisheries Boat Ramp Surveys 628 mm
- Mackay ranked 1st in the State for size of Saddletail Snapper
- 67% of fish reported at Qld Fisheries Boat Ramp surveys are released
- Mackay has the 13th highest rate of released fish in the state but due to small sample size there is high uncertainty in that ranking.
Limited Take For Consumption Advised
Saddletail 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.
- 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
Heavy harvesting of Saddletail Snapper is not recommended, but a moderate take for consumption is unlikely to adversely affect stocks based on available data.

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 Mackay report catching Saddletail Snappr with most being returned to the water. Monitoring began in 2017 and continues in 2018.
- Saddletail Snapper was a commonly reported species in Mackay in 2017, ranking 10th
- The average size of fish measured was 652.3mm
- Fishers reported an overall catch rate of 1.2 fish/fisher/day in 2017
- 67% of fish reported were released
- Peak periods for Saddletail Snapper catches in 2017 were during June and September
Saddletail 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

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 Saddletail Snapper in Mackay (maps O25, O26 and P24, P25 and P26 to X24, X25 and X26) represents 12.9% share of the total statewide catch. Monitoring is ongoing in 2018.
- Commercial Catch rate decreased, from 76.2kg/fisher/day in 2016 to 59.8kg/fisher/day in 2017
- The number of active licenses has ranged from 9-21 over the past decade with 21 licenses active in 2017
- Commercial Catch in 2017 was 7.83T, compared to 7.54T in 2016.
Monitoring of Saddletail Snapper Recruitment
No data is available currently on Crimson Snapper recruitment.
Monitoring of Saddletail Snapper
Data for this assessment has been sourced from:
- Bureau of Meterology
- Queensland Fisheries
- Local Sportfishers / Suntaggers
Here are links to all the monitoring pages for Saddletail Snapper:
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).
