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 a catch rate of 0.5 fish/fisher/day in 2017
- Mackay ranked 3rd in the state for Barred Javelin catch rates
- Not targeted commercially
Quality of the Fish
- An average length of 456mm was reported in 2017 Qld Fisheries Boat Ramp Surveys
- Mackay ranked 9th in the State for the average length of Barred Javelin
- 68% of fish reported by recreational fishers in the 2017 Qld Fisheries Boat Ramp Surveys were released
- 65% of fish reported in 2017 were caught by locals
- Mackay ranked 5th in the state for the number of fish released
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 Mackay report catching Barred Javelin with most being released. Monitoring began in 2017 and continues in 2018.
- Barred Javelin were the 3rd most commonly reported species in Mackay in 2017
- An average length of 456mm was reported by fishers in 2017
- Fishers reported a catch rate of 0.5 fish/fisher/day in 2017
- 68% of fish reported in 2017 were released
- The peak period for Barred Javelin catches in 2017 was during January
Barred Javelin as a Sports Species
Barred Javelin are a prized sports species in most locations across Queensland. In Hinchinbrook, Barred Javelin are sometimes targeted by Sportfishers.
- A catch rate of 1.14 fish/fisher/day has been reported in 2018, so far
- The catch mix in 2018, so far, is dominated by undersize fish (81%) followed by legal size fish (13%) then trophy fish (6%)
- The most common length reported so far in 2018, are fish in the 351-400mm size range

Monitoring of Barred Javelin Recruitment
Barred Javelin recruitment in Mackay is not directly assessed however, where individuals are caught during barramundi or bream surveys, the data is recorded.
