   Abstract:  Abundance estimates from tag-release and tag-recapture data require that the number ... and type of errors in data for analysis are minimised. Accurate recording of the sequence numbers on tags ... at time of release and recapture form an important part of data accuracy. Check digits, as a part ... of the tag sequence number, can assist in the identification of errors in recorded data. A computer program ...
