a new species of entobdella blainville in lamarck, 1818 (monogenea: capsalidae: entobdellinae) from the greenland halibut, reinhardtius hippoglossoides.	a previously undescribed species of entobdella is reported from the skin of the greenland halibut, reinhardtius hippoglossoides (pleuronectiformes, pleuronectidae). entobdella whittingtoni sp. nov. differs from other species of entobdella, including skin parasites of the related pleuronectids hippoglossus hippoglossus (atlantic halibut) and h. stenolepis (pacific halibut), in lacking papillae on the ventral surface of the haptor. other characteristics of e. whittingtoni are as follows: the absen ...	2015	26204173
killer whale depredation and associated costs to alaskan sablefish, pacific halibut and greenland turbot longliners.	killer whale (orcinus orca) depredation (whales stealing or damaging fish caught on fishing gear) adversely impacts demersal longline fisheries for sablefish (anoplopoma fimbria), pacific halibut (hippoglossus stenolepis) and greenland turbot (reinhardtius hippoglossoides) in the bering sea, aleutian islands and western gulf of alaska. these interactions increase direct costs and opportunity costs associated with catching fish and reduce the profitability of longline fishing in western alaska. t ...	2014	24558446
deep vision: an in-trawl stereo camera makes a step forward in monitoring the pelagic community.	ecosystem surveys are carried out annually in the barents sea by russia and norway to monitor the spatial distribution of ecosystem components and to study population dynamics. one component of the survey is mapping the upper pelagic zone using a trawl towed at several depths. however, the current technique with a single codend does not provide fine-scale spatial data needed to directly study species overlaps. an in-trawl camera system, deep vision, was mounted in front of the codend in order to ...	2014	25393121
anisakid nematodes of greenland halibut reinhardtius hippoglossoides from the barents sea.	parasitic nematodes from the body cavity of 94 greenland halibut (reinhardtius hippoglossoides) caught in the barents sea were examined. nematode species were identified using both morphological and molecular methods. four morphospecies were found: anisakis simplex s.l., contracaecum osculatum s.l., pseudoterranova decipiens s.l., and hysterothylacium aduncum. the most prevalent were c. osculatum s.l. (89.4%) and a. simplex s.l. (86.2%). mean intensities for these 2 species were 7.8 and 45.2, re ...	2013	23536987
myxobolus groenlandicus n. sp. (myxozoa) distorting skeletal structures and musculature of greenland halibut reinhardtius hippoglossoides (teleostei: pleuronectidae).	a specimen of greenland halibut reinhardtius hippoglossoides (walbaum, 1792) caught on the west coast of greenland (qasigiannguit) was found to possess serious pathological changes in the body musculature. a series of cartilaginous cylindrical structures organized symmetrically at the position of the proximal pterygiophores had changed the musculature and produced irreversible distortions (cavities and holes) in the fillet of the processed fish, leaving it with no value for the industry. histopa ...	2012	22436461
susceptibility of juvenile sole solea senegalensis to marine isolates of viral haemorrhagic septicaemia virus from wild and farmed fish.	the susceptibility of sole solea senegalensis to infection with 3 viral haemorrhagic septicaemia virus (vhsv) strains obtained from wild greenland halibut reinhardtius hippoglossoides and farmed turbot psetta maxima was demonstrated. fish were infected by an intraperitoneal (i.p.), immersion or cohabitational route, and maintained at 16 degrees c. infection trials showed that vhsv isolates were pathogenic for sole fingerlings by i.p. injection and waterborne exposure causing moderate levels of m ...	2011	21381517
selected mitochondrial genes as species markers of the arctic contracaecum osculatum complex.	this study, aimed at testing the hypothesis that some mitochondrial genes can serve as species-specific markers, involved a comparison of the sequence variance of selected mitochondrial dna genes of the arctic contracaecum osculatum species (c. osculatum a, c. osculatum b and c. osculatum c). we compared differences between five complete (nd2, cytb, nd3, nd4l and nd6) and three partial (co1, co3 and nd5) protein-coding genes. the total length of the sequence of each of the 13 specimens was 4830 ...	2011	21749741
mitochondrial dna of anisakis simplex s.s. as a potential tool for differentiating populations.	anisakis simplex s.s. specimens from gadus morhua, gadus ogac, reinhardtius hippoglossoides, clupea harengus, micromesistius poutassou, pleurogrammus monopterygius, and oncorhynchus nerka, caught in the north atlantic and pacific, were examined. identity of the parasite species was confirmed using a molecular key. all specimens were used for amplifying a part of the non-coding sequence of the at-rich region, flanked by the nad6-nad4l-trnw-trne-rrns-trns2, and trnn-trny-nad1 genes. this part of t ...	2009	19530887
halibut mitochondrial genomes contain extensive heteroplasmic tandem repeat arrays involved in dna recombination.	halibuts are commercially important flatfish species confined to the north pacific and north atlantic oceans. we have determined the complete mitochondrial genome sequences of four specimens each of atlantic halibut (hippoglossus hippoglossus), pacific halibut (hippoglossus stenolepis) and greenland halibut (reinhardtius hippoglossoides), and assessed the nucleotide variability within and between species.	2008	18186947
experimental infection of turbot, psetta maxima (l.), with strains of viral haemorrhagic septicaemia virus isolated from wild and farmed marine fish.	the susceptibility of turbot, psetta maxima, to infection with two strains of viral haemorrhagic septicaemia virus (vhsv) obtained from wild greenland halibut, reinhardtius hippoglossoides, and from farmed turbot was examined. a marine vhsv strain known to be highly pathogenic for turbot was also utilized for comparative purposes. fish were infected by intra-peritoneal (i.p.), immersion or cohabitation, and maintained at two different temperatures (8 and 15 degrees c). infection trials showed th ...	2007	17501740
genotyping of marine viral haemorrhagic septicaemia virus isolated from the flemish cap by nucleotide sequence analysis and restriction fragment length polymorphism patterns.	a total of 14 viral haemorrhagic septicaemia virus (vhsv) isolates obtained from greenland halibut reinhardtius hippoglossoides caught at the flemish cap, a fishing ground in the north atlantic ocean near newfoundland, were characterised using restriction fragment length polymorphism (rflp) and nucleotide sequence analysis. rflp analysis was performed on a 1259 bp fragment of the glycoprotein (g) gene, and a 305 nucleotide region within the nucleoprotein (n) gene was used for sequence analysis. ...	2006	17240749
molecular identification of nine commercial flaffish species by polymerase chain reaction-restriction fragment length polymorphism analysis of a segment of the cytochrome b region.	commercial refrigerated or frozen flatfish fillets are sometimes mislabeled, and identification of these mislabeled products is necessary to prevent fraudulent substitution. identification of nine commercial flatfish species (order pleuronectiformes), hippoglossus hippoglossus (halibut), lepidorhombus boscii (four-spotted scaldfish), lepidorhombus whiffiagonis (megrin), platichthys flesus (flounder), pleuronectes platessa (european plaice), reinhardtius hippoglossoides (greenland halibut), scoph ...	2002	12092715
isolation of viral hemorrhagic septicemia virus from greenland halibut reinhardtius hippoglossoides caught at the flemish cap.	viral hemorrhagic septicemia virus (vhsv) was isolated from apparently healthy greenland halibut reinhardtius hippoglossoides caught in the flemish cap, a deep fishing ground in the north atlantic ocean in international waters near newfoundland. the identity of the virus was confirmed by electron microscopy, immunodot, seroneutralization and reverse transcriptasepolymerase chain reaction. in the serology assays, all isolates reacted in the immunodot assay with a polyclonal antiserum against the ...	2002	12219973
arthrobacter rhombi sp. nov., isolated from greenland halibut (reinhardtius hippoglossoides).	two strains of a hitherto undescribed gram-positive coryneform bacterium isolated from greenland halibut (reinhardtius hippoglossoides) were characterized by phenotypic and molecular taxonomic methods. comparative 16s rrna gene sequencing studies demonstrated that the unknown strains constitute a new line within the genus arthrobacter. the nearest relatives of the bacterium from fish were members of the arthrobacter nicotianael arthrobacter sulfureus group. the unknown bacterium was readily dist ...	1999	10425782
