Description

Spotted Handfish (Brachionichthys hirsutus) were once common across the bays and estuaries of South-eastern Tasmania. By 1996, however, populations had declined and the species was listed as Critically Endangered under Australia’s Environment Protection and Biodiversity Conservation Act 1999. The species is relatively short-lived, (5–10 years) and matures at more than two years’ old. This leaves a short window for reproduction, which relies on egg masses laid on seafloor structures such as stalked ascidians. If spawning fails, population declines may occur rapidly. With no planktonic life stage to aid dispersal, and low adult dispersal, outside recruitment to re-establish collapsed populations is unlikely.

Analysis of 23 years of Spotted Handfish survey data (1997–2019) supported by previous NESP Marine Biodiversity Hub work Project A10 helped develop a time-series of survey data, increasing biological understanding and contributing to effective management actions. This project recommenced surveys of multiple local populations, after a two-year gap, to ensure that the potential impacts of development of the Derwent estuary and surrounds handfish populations or their habitats can be detected. Included in the population surveying was identification of suitable locations to plant Artificial Spawning Habitats (ASH) where natural spawning structures have declined. This will continue to support the species' captive breeding program with industry and foster engagement with the indigenous and broader community through participation, talks, outreach, publications, and the National Handfish Recovery Team (NHRT).
