Abstract

This study evaluated the effects of surgically implanted passive integrated transponder (PIT) tags on growth rate, survival and tag retention of yellow shortfin eels Anguilla australis with an initial mean mass of 101 g. There were no significant differences in body mass, total length, specific growth rate and survival between tagged and untagged A. australis in a 108 day laboratory trial. This tagging method was very reliable, with a tag retention of >95%.
