Furthermore, as new crustacean species are targeted and fished as commercial seafood, new species of pathogens may be discovered. This was the case in a recent finding in multiple Asian crustacean farm facilities. notes that only aquaculture species from southern and eastern China have been documented, which include swimming crab "P. trituberculatus", the mud crab "S. serrata", and the ridgetail white prawn "Exopalaemon carinicauda". In addition, a small new finding of "Hematodinium" parasites in crustaceans was also recently discovered in Russian waters. Recent findings from infected Chinese crustacean farms  In 2004, swimming crabs "P. trituberculatus" from Zhoushan were diagnosed with “milky disease” . They showed signs of lethargy due to the development of white muscle tissues and milky hemolymph. In addition, these crabs had a deficiency in cellular hemolymph and developed discoloured shells. Over 3000 acres of coastal aquatic culture was affected, with death rates as high as 60%. This was the first noted outbreak of its kind in China. In 2005, mud crabs "S. serrata" were infected with “yellow water disease” in Zhejiang Province . "Hematodinium" trophonts, prespores, and dinospore stages were present in studied individuals. Affected mud crabs were thinner than usual, had white muscle mass, and had abnormal milky liquids below the carapace. Other mud crab culture regions in that same year were also hit with "Hematodinium" infections. During transit in between shipments, affected crabs had a ‘cooked’ orange appearance and died shortly after. In 2008, a disastrous "Hematodinium" infection epidemic shook ridgetail white prawn ("E. carinicauda") aquacultures in Zhoushan . Shrimp were languid and had white muscles in their appendages. Most notable is the white colour of their hemolymph, giving the illness the name “milky shrimp disease.” Mortality rates reached 100%, completely wiping out many aquafarms. Research on the aforementioned epidemics show that the same parasite is able to infect multiple crustacean hosts, as amplified partial SSU gene and ITS1 rDNA regions from the parasite infecting ridgetail white prawn were exceedingly similar to the sequences from parasites infecting swimming crabs and mud crabs (Xu "et al.", 2010).
