“…Ryazanova also noted that the boiled meat from these crabs possessed a bitter astringent taste, similar to ''bitter crab disease/syndrome'' previously described from infected Tanner crabs (Meyers et al, 1987). In a follow up study, Ryazanova et al (2010) confirmed their earlier diagnosis by re-identifying and further characterizing Hematodinium in red and blue king crabs from 2006 and 2007 collection efforts from the northeastern area of the Sea of Okhotsk. Similar to their previous study, infected sublegal male and female red and blue king crabs displayed discolored hemolymph which was visible through arthrodial membranes, with large numbers of parasites distributed throughout the tissues, indicating that all were advanced infections.…”

“…In recent years, frequent outbreaks of Hematodinium spp. have been observed not only in a broad range of wild crustacean hosts, including American blue crab Callinectes sapidus (Messick & Shields 2000, Shields & Squyars 2000, snow crab Chionoecetes opilio (Meyers et al 1990, Taylor & Khan 1995, Alaskan Tanner crab Chionoecetes bairdi (Meyers et al 1987(Meyers et al , 1990, Norway lobster Nephrops norvegicus (Field et al 1992), red king crab Paralithodes camtschaticus and blue king crab Paralithodes platypus (Ryazanova et al 2010), but also in several cultured crustacean species, including Chinese swimming crab Portunus trituberculatus (Xu et al 2007a, Li et al 2013, mud crab Scylla paramamosain (formerly misidentified as S. serrata) (Xu et al 2007b, Li et al 2008) and ridgetail white prawn Exopalaemon carinicauda (Xu et al 2010). A high prevalence of infection (up to 100%) has been reported in Chionoecetes bairdi (Meyers et al 1987, 1990, Messick & Shields 2000 and Callinectes sapidus (Butler et al 2014, Gandy et al 2015.…”

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.

“…), and the Norway lobster ( Nephrops norvegicus ) from European waters [3-5]. Recognition of the broad ecological range of this parasite has led to increasing reports of infection in various fisheries [6-8]. In many affected crustacean species disease manifests as shell discoloration and ‘chalky’ hemolymph, discouraging human consumption [3].…”

Temporal distribution of genetically homogenous ‘free-living’ Hematodinium sp. in a Delmarva coastal ecosystem

BackgroundSignificant damage to crustacean fisheries worldwide has been associated with Hematodinium sp. It has been postulated that Hematodinium sp. requires passage through the water column and/or intermediate hosts to complete its life cycle. Thus, an understanding of the prevalence and seasonality of Hematodinium sp. within environmentally-derived samples should yield insight into potential modes of disease transmission, and how these relate to infection cycles in hosts.ResultsWe conducted a two year survey, from 2010–2011, in which 48 of 546 (8.8%) of environmental samples from the Maryland and Virginia coastal bays were positive for Hematodinium sp. between April and November, as based upon endpoint PCR analysis specific to blue crab isolates. Detection in both water and sediment was roughly equivalent, and there were no obvious seasonal patterns. However, there was a high detection in April water samples, which was unanticipated owing to the fact that crabs infected with Hematodinium sp. have not been observed in this early month of the seasonal disease cycle. Focusing on three sites of high prevalence (Sinnickson, VA; Tom’s Cove, VA; and Newport Bay, MD) Hematodinium sp. population diversity was analyzed using standard cloning methods. Of 131 clones, 109 (83.2%) were identical, 19 displayed a single nucleotide substitution, and 4 contain two nucleotide substitutions.ConclusionsOur data suggests a continuous presence of Hematodinium sp. in both water and sediment of a combined Maryland and Virginia coastal bay ecosystem. The detection of Hematodinium sp. in the water column in April is an earlier manifestation of the parasite than predicted, pointing to an as yet unknown stage in its development prior to infection. That the population is relatively homogenous ranging from April to November, at three distinct sites, supports a hypothesis that one species of Hematodinium is responsible for infections within the ecosystem.
