Koi herpesvirus (KHV) is a highly contagious virus that causes significant morbidity and mortality in common carp varieties. Common carp is raised as a foodfish in many countries and has also been selectively bred for the ornamental fish industry where it is known as koi. The first recognized case of KHV occurred in the United Kingdom in 1996. Since then other cases have been confirmed in almost all countries that culture koi and/or common carp with the exception of Australia. This 9-page fact sheet is intended to inform veterinarians, biologists, fish producers and hobbyists about KHV disease. Written by Kathleen H. Hartman, Roy P.E. Yanong, Deborah B. Pouder, B. Denise Petty, Ruth Francis-Floyd, Allen C. Riggs, and Thomas B. Waltzek, and published by the UF Department of Fisheries and Aquatic Sciences, April 2013.

Spring Viremia of Carp (VM142/VM106)
Spring viremia of carp is a viral disease that can cause significant mortality in several carp species including the common carp. It was reported in koi and feral carp in the United States for the first time in 2002. Diagnosis in farm raised fish in the U.S. may result in quarantine of the infected fish and depopulation. This 5-page fact sheet is intended to inform veterinarians, biologists, culturists, and hobbyists about Spring viremia of carp. Written by Barbara D. Petty, Ruth Francis-Floyd, and Roy P.E. Yanong, and published by the UF Department of Fisheries and Aquatic Sciences, August 2012.

Common Monogenean Parasites of Fishes (FA28/FA033)
Monogeneans are a class of parasitic flatworms that are commonly found on fishes and lower aquatic invertebrates. Most monogeneans are browsers that move about freely on the fish’s body surface feeding on mucus and epithelial cells of the skin and gills; however, a few adult monogeneans will remain permanently attached to a single site on the host. Some monogenean species invade the rectal cavity, ureter, body cavity, and even the blood vascular system. Between 4,000 and 5,000 species of monogeneans have been described. They are found on fishes in fresh and salt water and in a wide range of water temperatures. This 10-page fact sheet was written by Peggy Reed, Ruth Francis-Floyd, and RuthEllen Klinger, and published by the UF Department of Fisheries and Aquatic Sciences, June 2012.
