Our results showed the survival of the restocked eels in the six rivers and revealed significant differences between them in terms of total length, condition factor and density. During a three-year period, we monitored eels with respect to total length, annual growth rate, condition factor and density using capture-mark-recapture experiments to understand the effects of the characteristics of receiving rivers on restocking success levels. These rivers received a total of 76,370 imported glass eels in 2017.

The Department of Statistical Sciences and Operations Research provides statistical and programming consultation for the use of R in teaching and research.
