The spotted handfish (Brachionichthys hirsutus) is a rare Australian fish from the family Brachionichthyidae. It is classified as Critically Endangered on the IUCN Red List (last assessed ). It is a benthic fish usually found at depths of 5 to 10 m, with overall sightings varying from a minimum of 2 to a maximum of 30 m : Actinopterygii.
Spotted handfish are still seen around Hobart, and Australia has instituted a national recovery plan for some threatened species. Another species, Ziebell's handfish. The Australian government has instituted a recovery plan for four species of handfish, and a captive breeding program for the spotted handfish was Author: Brigit Katz.
In , the spotted handfish had the dubious distinction of becoming the first marine fish to appear on Australia’s endangered species list. Although the species was known to be abundant just a few decades ago, it’s now considered critically endangered—just steps away (as it were) from being extinct in the wild. The Spotted Handfish declined into being critically endangered since it is very sensitive to change in it's habitat. The handfish is affected by a loss of it's natural habitat as well as extreme contamination from metals and waste from humans. The only remaining habitat of the spotted Handfish is Derwent Estuary.

Third, as the spotted handfish is a local conservation icon we have been able to partner with community groups such as Rotary and institutions like the Tasmanian Museum and Art Gallery (TMAG) to conduct extensive outreach activities with the general public.

The Ziebell's Handfish is the most elusive of the three handfish species covered by the Handfish Conservation Project, with no confirmed sightings of a Ziebell's since They can be purple/ brown in colour, often with lighter patches on fins, or, in a second form, with bright yellow fins.
The Recovery Plan for four species of handfish is made for the purposes of the protection, conservation and management of the species of handfish covered in the Plan.
Administered by: Environment General Comments: This Recovery Plan was approved by the Minister for Environment and Heritage on 13 October See Supporting Material. Spawning behaviour of spotted handfish Aug We'd like to introduce you to a student studying spotted handfish reproductive behaviour at the Institute for Marine and Antarctic Studies (University of Tasmania) and CSIRO, within the Marine Biodiversity Hub in Hobart.
The spotted handfish is endemic to Tasmania s lower Derwent River estuary. Inthe spotted handfish became the first Australian marine fish to be listed as endangered. Scientists, government and the community are involved in a federally-funded recovery plan for the spotted handfish led by CSIRO Marine Research.
Spotted Handfish Facts Firstly, the most noteworthy fact about the Spotted Handfish remains its moderate air of mystery. It's a very rare ocean species, and not well studied. Yet, what we do know about it fascinates marine biologists. Secondly, its name derives from the presence of rather highly adapted pectoral fins.
These resemble human hands and are used to move along the ocean floor. Fifty million years ago, handfish were found trotting across the rivers of the world, but now these shallow bottom dwellers are some of the rarest animals on Earth.
The Spotted Handfish, with its unusually large overgrown pectoral fins that look like hands, is the darling of the Derwent estuary and the hero of Hobart.
We’re not being hyperbolic. We used the same 1-sample Z test approach reported by the spotted handfish recovery plan (Bruce and Green, ) to model our results for power analysis of sampling requirements.
This included comparing our results to data previously collected in /7 at the same site and season from 36 × m × 3 m reel parameterised by: 6.
