Can commercial harvest of long-spined sea urchins reduce the impact of urchin grazing on abalone and lobster fisheries?

At low-levels of exploitation, commercial harvesting of long-spined sea urchins was found to prevent increase in urchin density. Adjacent unfished locations experienced an increase in both urchin density and grazed area over the 2014 – 2016 study period. Research sampling of populations...

Rock Lobster Post Harvest Subprogram: development of a method for alleviating leg loss during post-harvest handling of rock lobsters

A novel brief application of cold-stunning was identified as a practical method for preventing post-harvest leg loss at several points in the post-harvest handling chain. Using this method, there is potential for the western rock lobster industry to save in excess of $2 million per season in lost...

Need

The Department of Agriculture and Water Resources is seeking expressions of interest for the revision of the following AQUAVETPLAN Disease strategy manual:
1. White Spot Disease

The Australian Aquatic Veterinary Emergency Plan (AQUAVETPLAN) is a series of manuals that outline Australia’s approach to national disease preparedness and propose the technical response and control strategies to be activated in a national aquatic animal disease emergency.
To assist potential applicants in preparing their expression of interest:
• Current AQUAVETPLAN manuals, including the current version of the AQUAVETPLAN manuals for White spot disease, is available on the Department’s website at AQUAVETPLAN.
• Author guidelines, including the latest template for AQUAVETPLAN manuals, can be provided electronically on request from the Aquatic Pest and Health Policy section (contact details below).
Terms of Reference
The White spot disease manual was first published in 2005, and the second version was published in 2013. This manual requires revision to reflect new scientific knowledge, and to ensure that strategies used for White Spot disease control purposes reflect current ‘best-practice’ approaches.

Objectives

1. Revision of the AQUAVETPLAN Disease Strategy Manual: White Spot Disease

Summary

This disease strategy for the control and eradication of white spot disease (WSD) is an integral part of the Australian Aquatic Veterinary Emergency Plan (AQUAVETPLAN).
AQUAVETPLAN disease strategy manuals are response manuals and do not include information about preventing the introduction of disease.
This strategy sets out the disease control principles for use in an aquatic veterinary emergency incident caused by the suspicion or confirmation of white spot disease in Australia. The strategy was scientifically reviewed by the Sub Committee for Aquatic Animal Health of the Animal Health Committee, before being endorsed by the Animal Health Committee of the National Biosecurity Committee in February 2020.
White spot disease is listed by the OIE in the Aquatic Animal Health Code. White spot disease is also listed on Australia’s National List of Reportable Diseases of Aquatic Animals (Agriculture 2019).

Aquatic Animal Health Subprogram: crayfish plague disease strategy manual

Crayfish plague is a serious disease of freshwater crayfish in Europe. The infectious agent, Aphanomyces astaci, is an Oomycete that produces hyphae and zoospores and is similar to a fungus. Studies have shown that Australian freshwater crayfish are susceptible to the disease but the disease has...

Rock Lobster Post Harvest Subprogram: quantifying and controlling hyper- and hyposaline-induced post-harvest leg autotomy in the western rock lobster

The previously undescribed phenomenon of hypersaline-induced autotomy in western rock lobsters has been fully characterised. The extent of occurrence of hypersaline films throughout the post-harvest chain has been examined and found to be significant. Environmental factors contributing to the...

Maximise yield or minimise risk in the Blacklip Abalone fishery: using biological data to direct harvest strategies

The primary goal of this research was to identify attributes of the seasonal biology of Blacklip Abalone (Haliotis rubra; hereafter referred to as Blacklip) that may be beneficial for optimising fishing strategies. The optimum months to harvest Blacklip to maximise yield were identified using a...
