The issue of whether or not there is bias in the current SBT monitoring process remains unresolved as highlighted by the findings of the recent O’Neill review commissioned by AFMA and the recent CCSBT farm review. In addition there is a need to re-evaluate the stereo video sampling method developed in previous SV projects to determine if it is cost effective, and an operationally feasible method which also meets required levels of accuracy and precision in an operational environment. The tests of accuracy and precision must be met in terms of aggregate catch within Australia’s national allocation under CCSBT, as well as AFMA’s domestic management obligations to measure SBT catch against individual SFR holdings.

Assessing the operational feasibility of the stereo video technology remains a very important domestic and international SBT management priority. There is a need to conduct appropriate trials to determine statistically acceptable levels of SBT sampling. The project must also determine accuracy of length measurements and apply this to individual and total aggregate catches.

There is a need to evaluate the use of stereo video technology under the range of conditions comparable to actual farm transfer conditions, particularly with regard to varying light and water visibility conditions and with a range of fish sizes. It will also provide important insight into practical implementations issue such as the time and technical expertise needed to set up and calibrate stereo video equipment, and the physical robustness of the equipment under operational conditions.
