Population genomic assessment of Australian Blacklip Abalone for abalone viral ganglioneuritis (AVG) resistance

Abalone viral ganglioneuritis (AVG) remains a significant threat to the economic viability and stability of the Abalone industry in south-eastern Australia. Consequently, there is an urgent need for strategic research aimed at determining the likely vulnerability of fisheries to future AVG outbreaks...

FRDC-DCCEE: preparing fisheries for climate change: identifying adaptation options for four key fisheries in South Eastern Australia

Over the next century, the marine ecosystems of south-eastern Australia are expected to exhibit some of the largest climate-driven changes in the Southern Hemisphere. The effects of these changes on communities and businesses will depend, in part, on how well fishing industries and resource managers...

Evaluating the effectiveness of marine protected areas as a fisheries management tool

Marine Protected Areas (MPAs) are being proclaimed around the world with the stated primary purposes of enhancing fisheries stocks and/or conserving marine biodiversity. In Australia, in response to a joint State/Commonwealth agreement to establish a National Representative System of MPAs (NRSMPA)...

Need

The abalone aquaculture industry requires a genetic audit of farm held stocks of greenlip and blacklip abalone to be conducted in order to identify current levels of genetic diversity, effective population sizes, and levels of coancestry/relatedness captured within individual farms and the wider industry.

This fundamental information is needed to guide future approaches to genetic improvement of farmed abalone.

Objectives

1. Conduct a genetic audit of farm held stocks of greenlip and blacklip abalone to identify current levels of genetic diversity, effective population sizes, and levels of coancestry/relatedness captured within individual farms and the wider industry.

Summary

Following the AVG virus, the number of broodstock that were available to produce hybrids was drastically reduced. This project was undertaken in order to ascertain the genetic diversity present within farm held broodstock of greenlip and blacklip abalone and to determine the degree of genetic differentiation of stocks within and between farms. A genetic audit of farm held stocks enables farmers to gain an understanding of the genetic resources held across the industry.
 
This report provides a genetic audit of farm held stocks of greenlip and blacklip abalone from six Australian farms across three states. Thousands of single nucleotide polymorphisms (SNPs) were used to calculate genetic diversity, genetic differentiation, effective population size and relatedness within and between farms and are reported for each species. A mate allocation plan is also presented which optimises the available genetic resources across farms in order to minimise kinship. The audit was carried out in 2016 and 2017 by Associate Professor Jan Strugnell and Dr Catarina Silva based within the Department of Marine Biology and Aquaculture at James Cook University, Australia.

Aquatic Animal Health and Biosecurity Subprogram: Perkinsus olseni in abalone - development of fit-for-purpose tools to support its management

The project was able to successfully propagate a new P. olseni isolate from Queensland and successfully cultured the isolates from Spain, Japan, New Zealand, and South Australia as well as P. chesapeaki, which was used as a negative control. We were unable to culture the Western Australian (WA)...
