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 sized fish kept or released)
- Qld Fisheries Boat Ramp Surveys reported a catch rate of 0.08 fish/fisher/day in 2017
- Local Sportfishers have reported a catch rate of 1 fish/fisher/day in 2018 so far
- The Whitsundays ranked 7th in the state for Dusky Flathead Catch Rates
- A decline in Commercial Catch Rates was reported in 2017 (4.21kg/day), from 5.45 kg/day in 2016
Quality of the Fish
- Qld Fisheries Boat Ramp Surveys reported the average length of Flathead caught in 2017 was 525mm
- The Whitsundays ranked 4th in the state for size of Flathead however, this ranking is based on 8 fish and is unreliable
- 75% of fish reported at Qld Fisheries Boat Ramp surveys were kept
- 100% of fish reported in 2017 were caught by visitors
- The Whitsundays ranked 4th in the state for the number of fish released

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 the Whitsundays report catching Flathead with more than half of all legal size fish being released. Monitoring began in 2017 and continues in 2018.
- Dusky Flathead was the 21st most commonly reported species in the Whitsundays in 2017
- A total for 8 were reported in the 2017 Qld Fisheries Boat Ramp Survey
- An average length of 525mm was reported in 2017
- Fishers reported an overall catch rate of 0.08 fish/fisher/day in 2017
- 75% of fish reported in 2017 were kept
- 100% of the total reported catch in 2017 were caught by visitors
- The Peak period for Dusky Flathead catches in 2017 was during April
Dusky Flathead as a Sports Species
Dusky Flathead are prized by Sportsfishers because they are an agressive species that respond to a wide variety of lures. Other species provide greater challenge, thus sportfishers tend to invest more time in the other species but when conditions are not ideal or a feed is desired, Flathead is an attractive option.
- Local Sportfishers have reported a catch rate of 1 fish/fisher/day in 2018, so far
- The single fish reported in 2018 was in the 501-600mm size range and legal

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 Dusky Flathead in the Whitsundays (see Area Fished section) represented 0.2% share of the total statewide catch in 2017. Monitoring is ongoing in 2018.
- Commercial Catch rate declined between 2016 and 2017 with 5.45 kg/fisher/day and 4.21 kg/fisher/day reported, respectively
- Number of active licenses has ranged between 5 and 10 over the last decade with 5 licences active in 2017.
- Commercial catch in 2017 was 0.08T, compared to 0.06T in 2016.
