  1. Number of days from tagging to sampling (days) with parameters describing retention and loss rates in each period: proportion of fish retaining their tag (R) scaled with time, proportion of fish with lost tags (loss) scaled with time, number of fish multiplied with time in years (IndYears), and number of lost tags per individual and years with a letter denoting rates significantly different at a 0.05 significance level
