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)
- Qld Fisheries Boat Ramp Surveys reported 4 Grey Mackerel in 2017 with a catch rate of 0.01 fish/fisher/day
- Cairns ranked 10th in the state for the catch rate of Grey Mackerel
- Commercial Catch not reported since 2015
Quality of the Fish
- 2017 Qld Fisheries Boat Ramp Surveys reported an average length of 565mm in 2017
- Cairns ranked 9th in the State for size of Grey Mackerel however, due to only four fish being reported, this ranking is unreliable
- No Grey Mackerel were reported by recreational or sport fishers in 2017
Moderate Take For Consumption Advised
- Boyne Tannum hookup catch rate between 1.2 and 1.6 fish/fisher/day
- 95% of Yellowfin Bream in the Boyne Tannum Hookup will be between 270 and 290mm
- Recruitment is likely to be moderate
Heavy harvesting of Bream is not recommended, but a moderate take for consumption is unlikely to adversely affect stocks based on available data. Evidence from the Qld Fisheries boat ramp surveys suggests that most fish are released but with only a single year of data, this will need to be assessed as additional data is collected.
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 Cairns report catching few Grey Mackerel with half being kept. Monitoring began in 2017 and continues in 2018.
- Grey Mackerel were one of the least commonly reported species in Cairns in 2017, ranking 32nd
- An average length of 565mm was reported by fishers in 2017
- Fishers reported a catch rate of 0.01 fish/fisher/day in 2017
- 50% of fish reported in 2017 were kept
Grey Mackerel as a Sports Species
No Grey Mackerel have been reported by sportfishers in Cairns in 2018, so far
A snapshot of Sportsfishers catch data is available:
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. No commercial catch data has been reported in Cairns since 2015.
Monitoring of Grey Mackerel Recruitment
Grey Mackerel recruitment is not currently assessed in Cairns.
Monitoring of Grey Mackerel
Data for this assessment has been sourced from:
