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 0.4 fish/fisher/day
- Rockhampton ranked 12th in the state for Bream Catch Rates
- Sportfishers reported an increase in catch rate from 0.1 fish/fisher/day in 2017 to 0.6 fish/fisher/day in 2018
Quality of the Fish
- 2017 Qld Fisheries Boat Ramp Surveys reported an average length of 316mm in 2017
- Rockhampton ranked 1st in the State for size of Bream
- 76% of legal size fish reported by recreational fishers in the Qld Fisheries Boat Ramp Surveys were kept
- 63% of fish reported in 2017 were caught by locals
- Rockhampton ranked 12th in the state for the release rate of fish
- The high average size indicates pressure on the species is lower than in Southern Region
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 Rockhampton regularly report catching Bream with most being kept for food. Monitoring began in 2017 and continues in 2018.
- Yellowfin Bream was the 15th most commonly reported species in Rockhampton in 2017
- An average size of 316mm was reported by fishers in 2017
- Fishers reported an overall catch rate of 0.04 fish/fisher/day in 2017
- 76% of fish reported in 2017 were kept
- 63% of fish reported were caught by locals
- Peak periods for Bream catches in 2017 were during June and November
Bream as a Sports Species
Yellowfin Bream are a sports species in South East Queensland where the opportunity to compete in the ABT Bream Tournaments is a motivator for fishers to develop their bream skills. In Rockhampton, Bream are not considered a sports species with limited catches of bream reported during the year by Sportsfishers. None the less catches are tracked and if members of the community wish to participated in data collection we would encourage contacting Infofish Australia.
- A catch rate of 0.6 fish/fisher/day has been reported forYellowfin Bream in 2018, so far
- The most commonly caught size of Bream so far in 2018 is 251-300mm
- 100% of the catch were legal size

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. Data for the commercial catch of Bream in Rockhampton ends in 2015 with 2016 seeing the establishment of the net free zone at the mouth of the Fitzroy River (refer to Fishing Area section).Rockhampton Bream Commercial Catch Dashboard
Importance of Bream to Tourism
Bream are not specifically a tourism drawcard but along with Whiting and Flathead, they are an important species for any family visitors. Family visitors are more likely to target species that are easier to locate in a short space of time.
Monitoring of Bream RecruitmentRecruitment is the success rate of juvenile fish surviving past the larval state. Bream Recruitment is monitored by the Gladstone Healthy Harbours Partnership. An extract of the current assessment is included below. A report on the development of the report card is available on the crystal-bowl website Report on development of Bream Report Card.For full details visit the Report Card website :http://ghhp.org.au/report-cards/2017/environmental.
Recruitment plays a key role in a fishery population, and the size distribution of fish gives an indication of bream successfully reaching and surpassing the juvenile stage.
There are no external criteria available to set baseline levels for fish recruitment therefore the scores were constructed with respect to internal criteria, derived objectively from the data itself.
A score of 0.50 equates to a year (season) at the median reference level, indicating no increase or decrease in the catch rate from the long term average. The 2017 score of 0.71 (B) for fish recruitment means that there is an increased catch rate relative to the median reference level. In other words, the model identified that the 2016-2017 season had a higher bream recruitment rate after correcting for a number of important environmental and temporal variables.
Note that variation in juvenile bream catch between years may be partly due to natural population cycles so care should be taken in interpreting results.
The overall harbour grade for the 2016-17 season was a B, which indicates good bream recruitment. This is a marked improvement relative to the 2015-16 season. All zones showed increased recruitment with only three zones reflecting poor-satisfactory recruitment (Graham creek, Boat Creek, Inner Harbour).2017 Technical Report Extract Bream and Crabs
