NCCP: Determination of the susceptibility of silver perch, Murray cod and rainbow trout to infection with CyHV-3

This research sought to build on the experimental evidence regarding non-target species susceptibility to CyHV-3. Three species which had been previously tested, but for which additional evidence would be needed to confirm non-susceptibility included Rainbow Trout, Silver Perch and Murray Cod.

NCCP: Understanding the genetics and genomics of carp strains and susceptibility to CyHV-3

To assess the risk that rapid resistance to CyHV-3 might develop, we undertook an extension to the integrated modelling with the objectives of defining what exactly is “resistance” in the context of viral biocontrol, and to elucidate the mechanisms (pathways) by which it might develop....

The End of an Era: Acknowledging the socio-cultural history and contribution of Australian small-scale fisheries

With little fanfare or attention, commercial fishing in the Gippsland Lakes in eastern Victoria ceased on 1 April 2020. The small-scale commercial fishery, which was crucial to the establishment of the town of Lakes Entrance roughly 150 years ago, was closed by the Victorian State...

Need

A review of genetic biocontrol options for carp in Australia will assist the Science Advisory Group (SAG) of the National Carp Control Plan (NCCP) and other decision-makers to identify suitable techniques or approaches for potential inclusion in the NCCP. At its third meeting, the SAG reviewed two applications to prepare genetic biocontrol technologies for use on carp in Australia. One application focussed on the ‘Daughterless Carp’ technology, while the other concentrated on the Trojan Y Chromosome technique. After discussing these applications, SAG members agreed that the group lacked sufficient knowledge to make a well-informed decision, and requested that NCCP management procure an expert review of genetic biocontrol technologies to clarify decision-making on research investment.
Most of the Australian experts with knowledge in this area already have considerable intellectual property invested in a particular technique. To ensure an independent perspective, NCCP management is therefore seeking an international expert to conduct the review.

Summary

This study was undertaken by Wedekind Gutachten, Switzerland. Potentially synergistic genetic biocontrol technologies can be grouped into those that do not involve engineered DNA sequences and those that do. The former include the “sterile male” and the “Trojan Y chromosome” technologies. The latter include genetic constructs that lead males to produce only male fertile offspring while daughters are either sterile or non-viable (“daughterless carp”), or to various types of engineered gene-drive technologies that would be sexually propagated but could still reach 100% inheritance. The high inheritance would allow them to spread even if the introduced engineered DNA sequence reduced the fitness of the host, for example by killing female offspring or rendering them infertile. Some gene-drive technologies could therefore lead to the extinction of a problem population. However, unintended spread of the engineered drive sequence beyond the target population is possible. Worst-case scenarios of applying gene-drive technologies may therefore include the extinction of an entire species, and, if gene flow is possible as is the case in many cyprinid fishes, of related species. 
Considering the biological effectiveness, the relevant logistical factors of each techniques, the risks involved, and their likely public acceptability, the potentially most appropriate technique for deployment against carp in Australia is the Trojan Y chromosome technology, specifically the production and release of mirror-type sex-reversed YY individuals, combined with all measures that increase the survival and fecundity of these stocked animals.

NCCP: essential studies on cyprinid herpesvirus 3 (CyHV-3) prior to release of the virus in Australian waters

This project, undertaken by CSIRO, aimed to determine the most important form of transmission of CyHV-3 to Cyprinus carpio (common carp). This was addressed through experiments to determine: (1) The relative amounts of virus in the skin and mucus of infected fish vs shed...
