Aquarium industry offers hope for Tasmania’s critically endangered handfish

Abstract

Southeast Australia, and most notably Tasmania, is the last home to the Handfishes, a unique group of marine fish that use their fins for walking. A range of threats occur across all species, with four listed as endangered, two as critically endangered, and the Red Handfish now on the brink of extinction. This paper summarises the contribution being made to the national recovery of the Spotted Handfish and Red Handfish by a captive breeding project underway at Beauty Point in northern Tasmania. Information is provided on husbandry techniques, survival and growth rates in captivity and a trial underway to identify their reproductive strategies. This program highlights the contribution the aquarium industry can make to improving the survival of two of the world’s most unique species of marine fishes and the collaboratives efforts of those involved.
