“Towards protecting indigenous fish and amphibian populations from disease risks posed by ornamental fish.”
 

The problem

Infectious diseases in European aquaculture are causing significant production losses and interruption to trade through preventive movement restrictions – many of these diseases are caused by the iridovirus group. Ornamental fish, i.e. non-indigenous species, may be vectors of systemic iridovirus and pose a threat to amphibian, farmed and indigenous fish species. A risk assessment model (RAM) applying epidemiological principles and methods needs to be developed to assess the potential pathways of spread and likely impact of viruses showing greatest virulence in experimental trials.

RANA  Identifying disease risk to native fish from ornamental fish species

Overview:

RANA will assess the threat of systemic iridoviruses to amphibians, and farmed and wild freshwater fish in the EU. It will:

  • Develop diagnostic methods for the detection of systemic iridoviruses in tissues of infected species
  • Develop methods to differentiate highly virulent strains from the less potent ones
  • Monitor disease in amphibians and ornamental fish to assess the presence of systemic iridoviruses
  • Make recommendations for preventing the incursion and spread of serious iridoviral diseases in the EU

Contribution to policy development:

  • RANA will provide scientific support for EU policy and legislation that prevents the spread of diseases among fish populations.
  • EU fish health legislation is currently under revision (SANCO/10774/2003) and RANA will provide any evidence of additional disease hazards for farmed fish and any need to protect the health of wild fish populations.
  • RANA will advise on whether new legislation should be brought in to apply health requirements to amphibians.
  • Evidence from the project will inform discussion on the need for any further trade restrictions.

Project deliverables

  • Report on the pathogenicity of systemic iridoviruses – November 2007
  • Evidence for whether ornamental fish can be vectors for iridoviruses – November 2007
  • Evidence for whether amphibians can be infected with, and be vectors for, iridoviruses – November 2007
  • Preliminary risk analysis of entrance and spread of one or more iridoviruses in Europe and the consequences – February 2008
  • Final report – May 2008

Dissemination

  • Project website presenting project objectives, schedule and progress – June 2005 and ongoing
  • Engage public participation in web-based survey of observed mortalities in ornamental fish and amphibians – September 2006
  • Technical workshop for laboratory technicians and post-graduate students – March 2006
  • Workshops with scientific, policy and industry stakeholders – October 2007
  • Conference to finalise and draft conclusions – March 2008
  • Preparation of results for publication in popular, trade and peer-reviewed international scientific journals – March 2008
