Orange roughy acoustic data processing

The first stock assessments of orange roughy were conducted in 2018 and the second full assessments are scheduled to be presented to the fourth SERAWG in March 2022 using the latest available data. In the first assessment, acoustic data were used as the abundance indices and the additional acoustic data needs to be incorporated into the second assessments. This short-term consultancy aim to collate and analyse the acoustic data and provide abundance estimates for use in the second assessments.
