OUTBREAK OF SPRING VIRAEMIA OF CARPDEFRA NEWS RELEASE The Department for Environment, Food and Rural Affairs (Defra) has issued an Order under the Diseases of Fish Act 1937, prohibiting the movement of fish to and from Gwinear Pools, Gwinear Farm, Cubert, Newquay, Cornwall comprising the Gwinear Pool, and the Windsor Pool, following an outbreak of a contagious viral disease in common carp. The outbreak of Spring Viraemia of Carp (SVC) has no implications for human health, but SVC is a serious viral disease affecting common and ornamental carp as well as a variety of other species including tench, roach, rudd, goldfish, pike and wels catfish. The Order was issued after tests at the CEFAS Weymouth laboratory confirmed the presence of SVC, a notifiable disease under the Diseases of Fish Act 1937. Fish Health Inspectors are investigating the source of the outbreak and tracing any fish that may have been in contact with fish at the infected site. Before the Order can be lifted, the site must test negative for SVC for three consecutive years. Alternatively, the Order could be lifted sooner if the infected site underwent an approved clearance and disinfection programme. The clinical signs of SVC can include darkening of the skin, swollen eyes, abdominal swelling, pale gills, trailing faecal casts and protrusion of the anus. Infected fish may be lethargic and show areas of bleeding in the gills and skin. Anyone noting deaths of carp or any other species susceptible to SVC, should immediately contact the Centre for Environment, Fisheries and Aquaculture Science (CEFAS), Weymouth Laboratory. Anyone who imports, keeps or retails carp or other susceptible fish should take strict precautions to prevent the spread of SVC and follow the advice set out in Defra's advisory booklet "Combating Fish Disease".
