Proportion of P. hemioliopterus in the state ‘moving > 10 km’ upstream (top panels) and model-averaged probability (solid lines) of being detected in that movement state (bottom panels) by month (season) and release site. The numbers on top of bars in the upper panels denote the total number of P. hemioliopterus known to be in the monitored area that month. The dashed lines in the lower panels denote model-averaged 95% confidence intervals. Predictions were computed for an averaged size individuals (defined as the mean of total length of tagged P. hemioliopterus) as well as for small and large individuals (defined as mean ± 1SD of total length of tagged P. hemioliopterus, respectively). Predictions are only shown for fish whose state at month t - 1 was ‘not detected / not detected moving upstream’, as they are virtually similar to the predictions where the previous month state was ‘moving > 10 km’ upstream.
