| hatching rhythms in the the capsalid monogeneans benedenia lutjani from the skin and b. rohdei from the gills of lutjanus carponotatus at heron island, queensland, australia. | spontaneous hatching of eggs of benedenia lutjani and b. rohdei occurred after incubation for 4-6 days and 6-10 days, respectively, at a constant temperature in the range 22-28 degrees c when exposed to natural illumination or to alternating 12-h periods of light and darkness (ld12:12; light on, 06.00 h; light off, 18.00 h). under these conditions, hatching of the eggs of both species was rhythmical, all larvae emerging only during periods of illumination. hatching was not confined to particular ... | 1996 | 9024862 |
| morphology and ultrastructure of the anterior adhesive areas of the capsalid monogenean parasites benedenia rohdei from the gills and b. lutjani from the pelvic fins of lutjanus carponotatus (pisces: lutjanidae). | the anterior adhesive areas of benedenia rohdei from the gills and b. lutjani from the pelvic fins of lutjanus carponotatus at heron island, australia, were studied using scanning and transmission electron microscopy. all specimens were fixed when detached from host tissue. both monogenean species have two disc-like anteroventral attachment organs, each of which has an anterolateral adhesive area divided into three adjacent zones by tegument from the ventral surface of the attachment organ. a ro ... | 1999 | 10227058 |
| experimental susceptibility of some reef fish species to benedenia lutjani (monogenea: capsalidae), a parasite of lutjanus carponotatus (pisces: lutjanidae). | the susceptibility of species of lutjanid, lethrinid and serranid fish to infection by either larval or post-larval (juvenile and adult) specimens of the capsalid monogenean benedenia lutjani whittington and kearn (1993) was examined experimentally. four species of lutjanids became infected when exposed to larvae of b. lutjani, but three species of lethrinids and four species of serranids were not susceptible to larvae under the same conditions. variability in the intensity of infection by larva ... | 2001 | 11355687 |
| migration, site-specificity and development of benedenia lutjani (monogenea: capsalidae) on the surface of its host, lutjanus carponotatus (pisces: lutjanidae). | life-history attributes of the capsalid monogenean benedenia lutjani, a parasite of lutjanus carponotatus from the great barrier reef, queensland, australia, were investigated from experimental infections. oncomiracidia of b. lutjani invaded and attached at any site on the fish, but more commonly invaded body surfaces. immature specimens then migrated to the pelvic fins. development of the reproductive organs of b. lutjani corresponded with migratory movements on the host. parasite aggregation o ... | 2002 | 12003066 |
| environmental induction of cyp1a-, cyp2m1- and cyp2k1-like proteins in tropical fish species by produced formation water on the northwest shelf of australia. | normal operation of oil well platforms results in the discharge of "produced formation water" (pfw). the expression of cyp1a, cyp2m1- and 2k1-like proteins was examined for use as possible biomarkers of pfw exposure. a pilot study at the harriet a production platform, on the northwest shelf of australia, had indicated that pfw contamination possibly contributes to induction of cyp1a- and 2k1/2m1-like proteins in gold-spotted trevally (carangoides fulvoguttatus). in a subsequent caged fish study ... | 2006 | 16709434 |
| biomarker induction in tropical fish species on the northwest shelf of australia by produced formation water. | normal operation of oil well platforms results in the discharge of produced formation water (pfw). the expression of cyp1a, cyp2m1- and 2k1-like proteins was examined for use as possible biomarkers of pfw exposure. a pilot study on the northwest shelf of australia had indicated that pfw contamination possibly contributes to induction of cyp1a-like proteins in gold-spotted trevally (carangoides fulvoguttatus). the pilot study samples were re-examined for cyp1a, and, in addition, cyp2k1/2m1-like p ... | 2008 | 18187187 |
| brain infecting kudoids of australia's coral reefs, including a description of kudoa lemniscati n. sp. (myxosporea: kudoidae) from lutjanus lemniscatus (perciformes: lutjanidae) off ningaloo reef, western australia. | a survey of the myxosporean fauna of australian marine fishes revealed the presence of a number of putative species of kudoidae (multivalvulida) forming pseudocysts between the outer meningeal layer and the outer surface of the brains of the lutjanids caesio cuning, lutjanus carponotatus, lutjanus ehrenbergii and lutjanus fulviflamma and the mugilid liza vaigiensis from lizard island on the great barrier reef, australia and lutjanus lemniscatus off ningaloo reef, western australia. morphometric ... | 2012 | 22260905 |
| philometrid nematodes (philometridae) from marine fishes off the northern coast of australia, including three new species. | based on light and scanning electron microscopical studies, the following nine species of philometridae (nemaoda: dracunculoidea) are described from female worms parasitizing marine perciform fishes belonging to six families off the northern coast australia (near darwin): philometra australiensis sp. n. from the swimbladder of the king threadfin polydactylus macrochir (günther) (polynemidae); p. epinepheli dewi et palm, 2013 from the operculum of the orange-spotted grouper epinephelus coioides ( ... | 2014 | 24684052 |
