• In areas for which sufficient data were available, an age-structured Time Series Analysis (TSA) analytical assessment method was used. TSA makes use of commercial catch-at-age and survey indices by age and can cope with the omission of poor quality or missing data. The estimates of abundance and fishing mortality are calculated with confidence intervals. The estimates from TSA are smoothed through time reflecting the fact that fisheries and stocks are likely to show gradual year to year changes. As a result, the estimates are slow to respond, for example, when the data do suggest that there has been a sudden change in the fishery. This can potentially result in under or over estimation of recent fishing mortality.
