Some missing length data are imputed using mass-length relationship, but the biomass for a transaction of e.g. 10 fish may be an aggregate biomass, rather than the unit weight. This then produces an incorrect larger size. Consider including a data filtering process where e.g. lengths > 3 sigmas from the mean are removed
