Resumo: | Although the bluefin assessment is based on catch-at-age data, ageing using hard parts is an expensive and d{fficult process. Therefore length data are converted into age for bluefin using a growth curve, i.e. age slicing. Where age is predicted from length using the inverse of the von Bertalanffy growth curve. Here we show how a simple method based on length data alone can be used to estimate population parameters such as total mortality (Z).
