This activity aims to deal with problems of length frequency extrapolation at the scale of the stock, based on data obtained from an unbalanced design. Linear modeling approaches will be used to identify the main factors that can affect length frequency histograms (season, area, gear, etc.) and propose post-stratification designs in order to extrapolate the catch at length at the scale of the stock.
