This project is needed to manage the FRDC investment that will be comprised of investments seafood related projects. Conducting projects within CRC SAAFE will provide linkages to additional resources, expertise and knowledge sharing that will improve project outputs and foster national collaboration in addition to that currently provided by the FRDC. This will include the research and industry participants that are partners of CRC SAAFE. Objectives: 1. Best practice AMR mitigation and management in the seafood industry and the aquatic environment. 2. Improved biosecurity and animal welfare through development of vaccines to minimise use of antibiotics. Read moreRead less
A Trivalent Vaccine For Sustainable Yellowtail Kingfish Growout

Summary
Optimised vaccines deliver improved animal health and avoid use of antimicrobials in the production of fish (Sommerset et al., Expert Review Vaccines 2005, 4, 89-101.). Australian YTK Photobacteriosis outbreaks have been reported in association with Photobacterium damselae subsp damselae (Pdd), Photobacterium damselae subspecies piscicida(Pdp) and various Vibrio harveyi(Vh) isolates (Matt Landos, Nicky Buller, unpublished). To support stable production of high quality finfish highly efficacious ....Optimised vaccines deliver improved animal health and avoid use of antimicrobials in the production of fish (Sommerset et al., Expert Review Vaccines 2005, 4, 89-101.). Australian YTK Photobacteriosis outbreaks have been reported in association with Photobacterium damselae subsp damselae (Pdd), Photobacterium damselae subspecies piscicida(Pdp) and various Vibrio harveyi(Vh) isolates (Matt Landos, Nicky Buller, unpublished). To support stable production of high quality finfish highly efficacious controls of microbial diseases are critical. Successful examples are currently employed in salmon (Yersinia ruckeri, Vibrio anguillarum) and barramundi (Streptococcus iniae) whereby disease outbreaks drove the need for vaccine development. These conditions are now both well controlled in vaccinated populations and have dramatically reduced reliance on administration of antibiotics. Currently, crude autogenous vaccines are in use with YTK for control of only Pdd in South Australia and Western Australia with some reported success. Recently Pdp has emerged as a significant pathogen in South Australian outbreaks. Reliable vaccination against Pdp has proven difficult in international experience using traditional autogenous and generic killed vaccine methods, hence increasingly research is exploring DNA vaccination methods to improve protection against this pathogen (Kato et al., Vaccine 2015, 33 (8), 1040-1045). It is also probable that antigenic diversity had been underestimated, given high diversity that recent sequencing technology has revealed in our preliminary research . Preparedness for the emergence of highly pathogenic Pdp strains is prudent to allow rapid controls to be developed, without incurring business-ending losses within the growing aquaculture sector, or having high levels of reliance on oral antibiotics. Genetic sequence data on isolates generated through this project can be used for epidemiological modelling, new rapid diagnostic typing tools and immediate response if disease emergence occurs in other finfish industries. Pdp is acknowledged as a serious pathogen internationally in species including yellowtail, cobia, flounder, seabream, pompano and sea bass. (Andreoni et al.J Immunol Res. 2014).
Objectives: 1. Generate comprehensive genome database of Australian isolates of Pdd, Pdp and Vh associated with Photobacteriosis outbreaks in YTK 2. Generate and supply diagnostic laboratory reagents and methods for typing Photobacterium and Vibrio isolates associated with YTK outbreaks. 3. Deliver optimised monovalent and multivalent (Pdd, Pdp, Vh) killed vaccines, with production outline, appropriate adjuvant type, dose, safety and efficacy profile in YTK, ready for manufacture.

Summary
The production and health performance of emerging aquaculture species, cobia and giant grouper, in former prawn farm pond and tank infrastructure is not well documented.

The development of these alternative species offers flexibility and new production opportunities to WSSV affected farms in SE Queensland, and elsewhere in Australia to expand aquaculture production more generally.
Fish health problems are a common cause of aquaculture business failure. In prior pilot trials, significant health challenges were encountered that require thorough veterinary investigation and intervention. The information learnt from investigations can then form components of a health management plan for the culture of these two species in SE Queensland, in various systems. The description of health challenges through veterinary outbreak investigation allows the development and costing of interventions to prevent or treat the issue. Over the 12 month time frame of this project, surveillance strategies can be developed for early detection of disease. Such health management strategies facilitate early response actions that can minimise losses associated with infectious disease.
One metric which influences the viability of aquaculture systems is the density at which a species can be farmed. This is particularly the case in RAS, where the infrastructure capital costs are high. This project will document the impacts of stocking density on health and production in RAS, cages and ponds.
Another element that strongly influences viability of aquaculture enterprises is the growth rates of stock that are able to be achieved. Generating data from systems farmed at commercial densities can assist in determining the suitability of various sites for expansion of farming these species in Australia.
Objectives: 1. Generate data on the production and health performance of Giant Grouper and Cobia in RAS, cages in a saline lake and in outdoor pond growout systems. 2. Field test production outcomes from an experimental recombinant autogenous vaccine for prevention of nodavirus in the Giant Grouper. 3. Assess market potential for various formats of cobia and grouper Read moreRead less
