Benchmarking for health and productivity in aquaculture

Benchmarking is a form of evaluation undertaken by comparing a measure with a standard. With its widespread adoption across many industries, benchmarking was identified as an important area for development in aquatic industries through the national strategic plan for aquatic animal health (AQUAPLAN...

Need

Abalone Growers Associations in Victoria, Tasmania and South Australia have given their support for the establishment of health monitoring programs of their farm’s stock, and are willing to contribute financially for establishing these and for ongoing monitoring. They see such programs as putting them in a unique position to to enable them to prevent disease in their stock and of meeting future market expectations in relation to health accreditation. This process is threatened by inadequate data on diseases in wild stock, and in some states by limited experience in abalone diagnosis.

Similarly the wild harvest abalone industry recognises vulnerability from a lack of knowledge of the occurrence and distribution of diseases in Australian wild stocks, in a climate where interstate translocation and trade access and quality issues are increasing. They also seek assurances on the health of farmed stock and of stock used for reseeding operations. As a result, the wild abalone sector and fisheries and animal health authorities in these states also strongly support a baseline survey of diseases present in the exploited abalone species, and development of improved surveillance capability.

The project is to acquire this background data on abalone disease, by a health survey covering the natural range of the exploited temperate abalone species. It includes the abalone aquaculture industry and the wild fishery in SA, Victoria, Tasmania, NSW and WA. The project will incorporate associated initial training, permanent presentation on collated results in accessible electronic format (CD and the subprogram’s website), and an abalone disease symposium to develop a net-work of state-based resources for on-going diagnosis, health certification and other shellfish health related functions at reasonable cost to the industry.

Development of the on-going state-based surveillance programs for aquaculture will progress in conjunction with this (without cost to the project), and with consultation with wild fisheries industries and managers, who will also benefit from improved capability for diagnostic and surveillance services.

Objectives

1. To undertake, over approximately one year, a single-round health survey of abalone from representative wild groups of commercial abalone species throughout their range in 5 states, using statistically relevant samples appropriate to maximize the chances of detection of serious diseases and define the disease agents present.
2. To similarly examine equivalent samples from all abalone farms and reseeding operations in these states.
3. From these to develop a database of abalone disease, their location and apparent prevalence (with confidence limits), then to present these findings to the wild and aquaculture industries and State and National government agencies, and to record them pictorially in accessible electronic format.
4. To expand the pool of abalone health expertise by holding an initial training workshop for collaborating pathologists to facilitate the survey, and a national abalone health meeting to present disease and pathology findings to all relevant pathologists and health service providers, to ensure their adoption.
5. Ensure the resulting information and skills are fully utilized by assisting in the development of cost-effective on-going health surveillance programs through collaboration with the abalone aquaculture industry and state authorities.

Need

With the emergence of AVG in in Victorian abalone in 2005/6, the subsequent discovery of several genetic variants of the causative agent, abalone herpesvirus (AbHV), associated with disease outbreaks in Tasmanian processing plants, and apparent variations in AbHV pathogenicity observed in different abalone species, there is the need to understand what factors promote disease in infected hosts. This project aims to address this knowledge gap and is relevant to all jurisdictions with abalone fisheries. Access to biosecure aquarium facilities, major abalone species and all known AbHV genotypes provides CSIRO-AAHL with a unique capability to investigate what factors influence disease outcomes following infection, including the nature of the AbHV genotype as well as abalone species or origins from locations spanning the primary wild fisheries in Victoria, Tasmania and South Australia. An improved understanding of the susceptibility of of abalone of different species and origins to infection by the various AbHV genotypes, and of whether different genotypes vary in their potential to transition from sub-clinical infection to acute disease is important for instructing fisheries and aquaculture policies and strategies to avoid disease, especially in aquaculture and abalone processing facilities. This project addresses specific priorities detailed in the current FRDC Aquatic Animal Health Subprogram R&D Plan (viz. 6.2.1 Nature of disease and host-pathogen interaction), priorities identified in the National Abalone Health Work Plan developed by a committee of national representatives following the second Abalone Virus Scientific and Management Forum held in Melbourne in 2007, and FRDC’s 2013 Annual Competitive Round Call for Expressions Of Interest (viz. Determining risk factors for AVG).

Objectives

1. Determine the susceptibility of greenlip, blacklip, hybrid and other readily available abalone species to abalone herpesvirus (AbHV) genotypes
2. Determine the complete genome sequences for AbHV Tas3 and Tas4 to gain insights into how and over what timeframe they have arisen, whether genetic recombination is contributing to this variation and which genome regions might affect virulence, as well as instructing on how diagnostic methods for their detection and diffferentiation can be refined.

Aquatic Animal Health Subprogram: enhancement of the emergency disease management capability in Victoria - adapting the AQUAVETPLAN control centre management manual

In the past 20 years, many fisheries and aquaculture industries around the world have suffered major production losses through the impact of disease epidemics. To date, Australia has avoided many of these epidemics and retains a favourable disease status, which facilitates international trade and...

Aquatic Animal Health Subprogram: development of management strategies for herpes-like virus infection of abalone

In January 2006, a previously unknown herpes‐like virus was identified as being the most likely cause of mass mortalities of abalone (Haliotis spp.) in a number of aquaculture farms in south‐west and central Victoria (Hardy‐Smith, 2006). The disease caused by the virus was named abalone viral...
