A check performed on the method used by de Moor (2020a) to suggest how much small (<14cm) sardine bycatch could be realistically expected with the anchovy catch during 2020 shows the prediction method was rather accurate using the ratio of sardine : anchovy measured in numbers (although the prediction was based on an anchovy TAC that was not realised). This same method is used to suggest how much small sardine bycatch could be realistically expected with the anchovy catch during 2021.
