three unicapsula species (myxosporea: trilosporidae) of asian marine fishes, including the description of unicapsula setoensis n. sp. in the yellowfin goby (acanthogobius flavimanus) from the inland sea of japan.the myxosporean genus unicapsula (multivalvulida: trilosporidae) is defined as having a spore with three unequal shell valves and polar capsules, of which one is prominent and the two other polar capsules are rudimentary. genetic characterization of members of the genus, currently 11 nominal species, is, at present, unsatisfactory yet when comparing to the closely related genus kudoa (multivalvulida: kudoidae). in the present study, we characterized long ribosomal rna gene (rdna) sequences of th ...201425088472
comparative metabolomic and ionomic approach for abundant fishes in estuarine environments of japan.environmental metabolomics or ionomics is widely used to characterize the effects of environmental stressors on the health of aquatic organisms. however, most studies have focused on liver and muscle tissues of fish, and little is known about how the other organs are affected by environmental perturbations and effects such as metal pollutants or eutrophication. we examined the metabolic and mineral profiles of three kinds of abundant fishes in estuarine ecosystem, yellowfin goby, urohaze-goby, a ...201425387575
comparison of the visual capabilities of an amphibious and an aquatic goby that inhabit tidal mudflats.the mudskipper periophthalmus modestus and the yellowfin goby acanthogobius flavimanus are gobiid teleosts that both inhabit the intertidal mudflats in estuaries. while p. modestus has an amphibious lifestyle and forages on the exposed mudflat during low tide, the aquatic a. flavimanus can be found at the same mudflat at high tide. this study primarily aimed to elucidate the differential adaptations of these organisms to their respective habitats by comparing visual capacities and motor control ...201626967712
henneguya sp. in yellowfin goby acanthogobius flavimanus from the san francisco estuary.myxozoan spores were observed in yellowfin goby acanthogobius flavimanus collected from suisun marsh, san francisco estuary (sfe). although histopathological changes associated with the parasite were not observed, the spores formed plasmodia that partially blocked the gastric and intestinal mucosa and gut lumen and may affect the perfomance and survival of the yellowfin goby. morphological features of the spores resembled henneguya sp. and molecular analysis of the 18s ribosomal dna (domain iii) ...201324024104

life cycle of hysterothylacium haze (nematoda: anisakidae: raphidascaridinae).natural infections with hysterothylacium haze in the japanese common goby, acanthogobius flavimanus, were observed in detail. in gobies in which no worm eggs were deposited, second-stage larvae were found in the digestive tract wall, and third-stage larvae occurred in the digestive tract wall, mesentery, and body cavity, whereas fourth-stage larvae and adults were found in the body cavity. this stage-habitat relationship demonstrates the infectivity of second-stage larvae to the goby and the lar ...19892795378
molecular identification and transmission studies of x-cell parasites from atlantic cod gadus morhua (gadiformes: gadidae) and the northern black flounder pseudopleuronectes obscurus (pleuronectiformes: pleuronectidae).epidermal pseudotumours from hippoglossoides dubius and acanthogobius flavimanus in japan and gill lesions in limanda limanda from the uk have been shown to be caused by phylogenetically related protozoan parasites, known collectively as x-cells. however, the phylogenetic position of the x-cell group is not well supported within any of the existing protozoan phyla and they are currently thought to be members of the alveolata.ultrastructural features of x-cells in fish pseudotumours are somewhat ...201121299903
identification of acanthotrema felis (digenea: heterophyidae) metacercariae encysted in the brackish water fish acanthogobius flavimanus.the metacercariae of acanthotrema felis sohn et al., 2003 (digenea: heterophyidae) were discovered in a species of the brackish water fish, acanthogobius flavimanus, in the republic of korea. they were experimentally fed to kittens, and adult flukes were harvested 7 days later. the adults were morphologically characterized by the presence of a bipartite seminal vesicle, the ventral sucker associated with a ventrogenital sac enclosing 3 sclerites (2 long and pointed, and 1 short and thumb-like), ...200312815321
x-cells in pseudotumors of yellowfin goby acanthogobius flavimanus: a protistan organism distinct from that in flathead flounder hippoglossoides dubius.yellowfin goby acanthogobius flavimanus affected with x-cell pseudotumors were sampled from a river estuary in tokyo bay, japan. we amplified the gene for small subunit ribosomal rna (18s rrna) of x-cells of the goby with pcr using universal primers. the gene that we obtained (ddbj accession no. ab451874) showed 91% sequence identity to that of the x-cells of the flathead flounder hippoglossoides dubius. with in situ hybridization, the probes specific for the gene that we obtained hybridized wit ...200919593933
