Lymphocystivirus cause mass mortality events like megalocytiviruses and ranaviruses, fish with lymphocystis exhibit grossly visible papilloma-like skin lesions which substantially reduce their commercial value. No vaccines are currently available for lymphocystis viruses. Group: dsDNA The genus "Lymphocystivirus" has only one species: "Lymphocystis disease virus 1" (LCDV-1), but Lymphocystis disease virus 2 (LCD-2) is another virus that has been proposed as a second member. LCDV-1 infects European flounder "Platichthys flesus" and European plaice ("Pleuronectes platessa"). LCDV-2 infects the common dab ("Limanda limanda"). A third species Lymphocystis disease virus C has also been proposed based on the relative lack of sequence similarity of
Orange-spotted trevally section being longer than the posterior straight section. The straight section of the lateral line has 14 to 26 scales followed by 20 to 30 scutes. The chest of the orange-spotted trevally is completely scaled, occasionally having a narrow naked region on the underside near the ventral fins. It has 24 vertebrae and 25 to 43 gill rakers. The orange-spotted trevally has a silvery grey- to brassy-coloured body, becoming paler to a silvery white ventrally. Many conspicuous orange to yellow spots occur on the sides of the fish, giving the species its name, and make for an easy way to
