SCRC: Population genetic structure of Sea Cucumbers (bêche-de-mer) in Northern Australia

Sandfish (Holothuria scabra), a commercially important species of Sea Cucumber, are fished off the northern Australian coast. Elsewhere in the Asia-Pacific region, where they are commonly fished, they have been found to be particularly vulnerable to over-exploitation. Currently, as little is known...

SCRC: SCRC Honours Scholarship H4.5 Improved Yellowtail Kingfish Growth Response, Flesh Quality and PUFA content through Biorefinery Microalgae LC-PUFA Aqua-Feed Additives (Prof Wei Zhang; Student Kopano Maso Machailo)

Yellowtail Kingfish is an emerging aquaculture species, and there is an increase in the demand for the fish, both for recreational fishing and for export purposes. This has led to the growth of the aquaculture industry that specialises in culture of yellowtail kingfish in South Australia. Currently...

Understanding Ostreid herpesvirus type 1 risk: alternative hosts and in situ hybridisation

South Australia (SA) has a large edible oyster industry primarily growing Pacific oysters (Crassostrea gigas). The industry is regionally-based, an important employer and a substantial contributor to regional economies. Pacific oyster mortality syndrome (POMS) is a serious infectious disease of C....

SCRC: PhD Extension : RNA interference (RNAi) as a means to control Neoparamoeba perurans, the causative agent of amoebic gill disease (AGD). (Student: Paula Lima)

RNA interference has emerged as a powerful tool for rapid analysis of gene function in non-model organisms and has the potential to identify candidate targets for interventions against diseases of economic importance to aquaculture. The main purpose of the study was to use functional and comparative...

Need

In late 2005, a sudden mass mortality in abalone resulting from abalone viral ganglioneuritis (AVG) occurred almost simultaneously on three abalone farms in Victoria. In May 2006, AVG was detected in wild stocks along the Victorian coast near one of the infected farms (Appleford, 2006). The outbreak in wild populations has subsequently been detected in both directions along the Victorian coast. A control zone was established to prevent movement of abalone, other invertebrates and fishing gear in and out of the infected area. Nevertheless, the virus has now spread beyond the control zone (Appleford, 2006; Handlinger, 2007). This presents an enormous threat to the lucrative commercial abalone fishery in Victoria and South Australia, as the range of the virus is currently nearing the South Australian border. Due to the difficulty in containing invasive pathogens in the marine environment, the outbreak of AVG in wild abalone populations is considered to be an issue of national concern.

In a recent report to industry on the research priorities related to the AVG outbreak, Handlinger (2007) identified the need to understand host-virus interactions and the host response. Handlinger (2007) further highlights the need for effective disease surveillance in both the wild and farming abalone sectors, as well as the need to establish health status as part of the family lines program, particularly with respect to the movement of broodstock. This requires the effective identification of infected abalone, including those sub-clinically infected and which harbor persistent virus. Consequently, investigation into the host antiviral response to AVG is timely and worthwhile to help ensure the ongoing economic viability of abalone industries faced with sudden mass mortality events from viral outbreaks.
