first report of gastrocotylinean post-oncomiracidia (platyhelminthes: monogenoidea: heteronchoinea) on gills of flyingfish (exocoetidae), snapper (lutjanidae), dolphinfish (coryphaenidae), and amberjack (carangidae) from the gulf of mexico: decoy hosts and the dilution effect.larvae, identified as post-oncomiracidia of the suborder gastrocotylinea (monogenoidea), were collected from formalin-fixed gills excised from six species of marine fishes captured from the gulf of mexico off mississippi and florida: common dolphinfish, coryphaena hippurus and pompano dolphinfish, coryphaena equiselis (both perciformes, coryphaenidae); gray snapper, lutjanus griseus (perciformes, lutjanidae); greater amberjack, seriola dumerili (perciformes, carangidae); and atlantic flyingfish, ...201121497672
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
structural characterization of carangid fish myoglobins.the primary structures of myoglobin (mb) from the following five carangid species were determined: yellowtail seriola quinqueradiata, greater amberjack seriola dumerili, yellowtail kingfish seriola lalandi, japanese horse mackerel trachurus japonicus, and silver trevally pseudocaranx dentex. the sequences were of varying composition both in the coding and in the noncoding regions, but all contained the open reading frame of 444 nucleotides encoding 147 amino acids. amino acid sequence identities ...201222361749
histochemical and morphometric aspects of the lateral musculature of different species of teleost marine fish of the percomorphi order.cross-sections of the lateral musculature of 19 species of teleost fish of the percomorphi order were studied histochemically and morphometrically. the red, pink and white muscles were observed in all the species except in seriola dumerilii and scomber japonicus, in which no pink muscle was found. the red fibres were the smallest due to their minimal diameters. histochemically and according to their location at least five types were found in the same species: typical red, in rosette, of the bord ...200011008368
