“…Protistan pathogens have been widely reported from crustacean hosts. A wide taxonomic spectrum of protists infect non-commercial hosts such as the shore crab Carcinus maenas (Stentiford and Feist, 2005) while several parasites within this group, including parasitic dinoflagellates of the genus Hematodinium, cause potent disease in an increasing range of commercially exploited decapod crustaceans (Stentiford and Shields, 2005;Morado, 2011;Small, 2012). Others, including representatives of the Phylum Microsporidia (protistfungal border) are described infecting hosts across a wide range of habitat types from freshwater to marine, and cause patent disease in affected hosts.…”

“…PaV1 infection of spiny lobsters), most reported cases of disease occurring at significant prevalence in wild crustaceans relate to infection by protistan pathogens. In particular, attention in the past two decades has focussed on the Hematodinium-like parasitic dinoflagellates infecting a growing number of decapod crustacean species (for review see Stentiford and Shields, 2005;Small, 2012). In the majority of hosts studied to date, infection leads to a characteristic disease state in which the haemolymph is progressively invaded by vegetative and sporolative stages of the dinoflagellate.…”

“…The parasitic dinoflagellates in the genus Hematodinium are emerging infectious pathogens in many decapod crustaceans worldwide, resulting in serious commercial losses to fisheries and the aquaculture of various economically important crustaceans (Xu et al 2007a, Y. Li et al 2008, Small 2012. In recent years, frequent outbreaks of Hematodinium spp.…”

The parasitic dinoflagellate Hematodinium spp. infects a broad range of marine crustaceans. Its epidemics have impacted wild populations of various commercial fishery species around the world and the sustainability of mariculture in China. To study the epidemiology of Hematodinium spp. in marine crustaceans along the coast of China, we conducted a broad survey of wild and cultured stocks of major crustacean species in 2013 to 2015. Hematodinium sp. infections were identified in wild stocks of Portunus trituberculatus from Huludao, Laizhou, Qingdao, Yangtze River Estuary and Zhoushan, and Scylla paramamosain from Shantou; and cultured stocks of Portunus trituberculatus and Penaeus monodon from a polyculture pond in Qingdao. In the polyculture pond, Hematodinium sp. infections were observed in Portunus trituberculatus from June until October, with peak prevalence (up to 90%) observed in late July to early August. Furthermore, Hematodinium sp. infection was identified for the first time in the giant tiger prawn Penaeus monodon in the polyculture system during the disease outbreak. Phylogenetic analysis indicated that the Hematodinium isolate infecting Penaeus monodon was identical to the isolate infecting the co-cultured Portunus trituberculatus, and it was grouped into H. perezi genotype II together with the other isolates reported in China. The Hematodinium sp. isolated from Portunus trituberculatus appeared to have similar life stages as the H. perezi genotype III isolated from the American blue crab Callinectes sapidus. Our study indicates that outbreaks of Hematodinium disease can be a significant threat to the widely used polyculture system for decapods in China that may be particularly vulnerable to such generalist pathogens.

“…Hematodinium sp. is a dinoflagellate parasite with broad host specificity, infecting more than 35 crustacean host species (Small 2012). It has had devastating impacts on crab populations worldwide (Morado 2011) and is a major source of mortality for juvenile Norway lobster Nephrops norvegicus around the UK.…”

Lobsters are prized by commercial and recreational fishermen worldwide, and their populations are therefore buffeted by fishery practices. But lobsters also remain integral members of their benthic communities where predator−prey relationships, competitive interactions, and host−pathogen dynamics push and pull at their population dynamics. Although lobsters have few reported pathogens and parasites relative to other decapod crustaceans, the rise of diseases with consequences for lobster fisheries and aquaculture has spotlighted the importance of disease for lobster biology, population dynamics and ecology. Researchers, managers, and fishers thus increasingly recognize the need to understand lobster pathogens and parasites so they can be managed proactively and their impacts minimized where possible. At the 2011 International Conference and Workshop on Lobster Biology and Management a special session on lobster diseases was convened and this special issue of Diseases of Aquatic Organisms highlights those proceedings with a suite of articles focused on diseases discussed during that session.
