The vertical bars indicate the times of the initial net distribution and of the surveys and the status at survey; the coloured bands connecting surveys indicate transition flows where the colors indicate the status of the nets at the previous survey; the height of the bands corresponds to the proportion of nets undergoing the transitions indicated among all survey intervals with both initial and final status defined. The transition probabilities between categories were calculated separately for each inter-survey interval. Attrited was defined as for analysis A1
