. Larval mycosis, Fungus disease, Lagenidium or Sirolipidium disease. Scientific name or taxonomic affiliation Lagenidium callinectes, Lagenidium spp., and Sirolpidium spp. Other phycomycetous fungi such as Phythium spp., Leptolegnia marina, and Haliphthoros milfordensis may also occassionally cause the disease. Geographic distribution Ubiquitous. Host species All penaeids especially in zoea and mysis stages as well as Pandalus platyceros under experimental culture conditions. Other marine crustaceans such as lobsters and crabs can also be infected. Impact on the host Extensive non-septate highly branched fungal mycelia throughout the body and appendages, replacing all the tissue. Specialised hyphae may protrude through the cuticle. Epizootics develop within 2-3 days; invariably lethal. Diagnostic techniques Wet Mounts or Histology: If necessary, the fungus can be identified by examining the method of sporogenesis and the morphology of spore discharge tube. Culture: In vitro on marine mycological media; sporulation induced by transfer to seawater. Methods of Control Control by disinfecting tanks and equipment and incoming water. There is speculation that antibiotic use to control bacteria may enhance larval mycosis by removing bacterial epibiont competitors. .
