| 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 |
| 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 |
