  • This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "Conservation of spotted handfish". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Spotted handfish are a critically endangered fish that inhabit a rapidly developing coast. This bridging project continues efforts to conserve the species with on-ground actions guided by research. Previous NESP work (A10) helped developed a 23-year time-series of surveys, increased biological understanding and established effective management actions. This new work will recommence surveys of multiple local populations, after a two-year gap, to ensure potential impacts of development of the Derwent estuary and surrounds handfish populations or their habitats can be detected. We will also identify where to plant Artificial Spawning Habitats (ASH) where natural spawning structures have declined. We will continue to support our 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). Outputs • A consolidated database of all available data on spotted handfish imagery, length frequency, and GPS regions to 2022 [time-series database] • Final technical report with analysed data, including a short summary of recommendations for policy makers of key findings [written]

  • Nitrogen stable isotope data from soil, leaf and spider samples collected from invaded, never invaded and eradicated islands around New Zealand's north island; and associated R code used to investigate the use of stable isotope analysis as a post-eradication ecosystem function assessment tool.
