Regeneration of the caudal and pectoral fins of a bony fish, Gambusia (Haplochilus) schoelleri.

The study showed that excision of the caudal fin at basal level was followed by complete regeneration in one and a half months, whereas if it was amputated at mid-fin level, complete regeneration took two months. The findings confirm that the greater the extent of amputation, the faster the rate of regeneration. In the case of the pectoral fin, only part of which was removed, it was found that the fin completely regenerated, with recovery of its original pattern, within two months after amputation.
