Integrated stock assessments provide estimates of stock status based on all available data and information. Stock status is the current biomass of the stock as a percentage of the biomass before the stock was fished. This report presents an integrated stock assessment model for scampi in the Auckland Islands (SCI 6A) that was not accepted by the Fisheries New Zealand Deepwater Working Group for the assessment of this stock. It includes information on the biology of scampi and data from commercial fisheries and research surveys. The model used two annual time-steps to reflect changes in vulnerability of males and females as moulting occurs at different times. Key concerns with the model were on the input data and suggest more work is required to understand inconsistencies within and between the datasets.
