| effects of temperature, salinity, desiccation and chemical treatments on egg embryonation and hatching success of benedenia seriolae (monogenea: capsalidae), a parasite of farmed seriola spp. | the effects of temperature and salinity on the embryonation period and hatching success of eggs of benedenia seriolae were investigated. temperature strongly influenced embryonation period; eggs first hatched 5 days after laying at 28 degrees c and 16 days after laying at 14 degrees c. the relationship between temperature and embryonation period is described by quadratic regression equations for time to first and last hatching. hatching success was >70% for b. seriolae eggs incubated at temperat ... | 2005 | 15752276 |
| closing the mitochondrial circle on paraphyly of the monogenea (platyhelminthes) infers evolution in the diet of parasitic flatworms. | relationships between the three classes of neodermata (parasitic platyhelminthes) are much debated and restrict our understanding of the evolution of parasitism and contingent adaptations. the historic view of a sister relationship between cestoda and monogenea (cercomeromorphae; larvae bearing posterior hooks) has been dismissed and the weight of evidence against monogenean monophyly has mounted. we present the nucleotide sequence of the complete mitochondrial (mt) genome of benedenia seriolae ... | 2010 | 20493870 |
| egg-laying patterns and in vivo egg production in the monogenean parasites heteraxine heterocerca and benedenia seriolae from japanese yellowtail seriola quinqueradiata. | egg-laying patterns and egg production in heteraxine heterocerca from the gills and benedenia seriolae from the skin of japanese yellowtail seriola quinqueradiata in japan were investigated in vivo. eggs were collected every 3 h from sexually mature h. heterocerca and b. seriolae infecting 3 s. quinqueradiata kept individually over 3 consecutive days and exposed to alternating periods of illumination and darkness (ld 12:12; light on 06.00, light off 18.00) and maintained at 23.8 +/- 0.1 degrees ... | 2008 | 18700993 |
| efficacy of orally administered praziquantel against zeuxapta seriolae and benedenia seriolae (monogenea) in yellowtail kingfish seriola lalandi. | we investigated the efficacy of praziquantel (pzq) administered orally to yellowtail kingfish (seriola lalandi in sea-cage aquaculture in south australia) against the monogeneans zeuxapta seriolae and benedenia seriolae infesting gills and skin, respectively. pzq was administered to fish by surface-coating feed pellets (trial 1) or by direct intubation of the stomach (trial 2). in both trials 4 daily doses were administered: 50 and 75 mg kg(-1) body weight (bw) d(-1) for 6 d, and 100 and 150 mg ... | 2007 | 18062471 |
| effect of water temperature on reproductive development of benedenia seriolae (monogenea: capsalidae) from seriola lalandi in australia. | the monogenean benedenia seriolae (yamaguti, 1934) meserve, 1938 is a major pathogen of farmed yellowtail kingfish seriola lalandi in south australia. to control parasite populations in commercial farms, an understanding of the effect of water temperature on parasite development is vital. this study investigated the effect of water temperature (14, 18, 22 and 26 +/- 0.5 degrees c) on development, growth rates and age at sexual maturity of b. seriolae. five distinct developmental stages, defined ... | 2007 | 17465308 |
| effects of temperature on fecundity in vitro, egg hatching and reproductive development of benedenia seriolae and zeuxapta seriolae (monogenea) parasitic on yellowtail kingfish seriola lalandi. | globally, aquaculture industries involved with commercial culture of kingfish (seriola spp.) experience outbreaks of monogenean parasites, which can cause heavy stock losses. in australia and new zealand, aquaculturists of kingfish seriola lalandi incur financial losses caused by two monogenean species: benedenia seriolae and zeuxapta seriolae which parasitise the skin and gills, respectively. this study provides information on some basic temperature-dependent life-cycle parameters of these prob ... | 2004 | 15722083 |
| attachment-inducing capacities of fish skin epithelial extracts on oncomiracidia of benedenia seriolae (monogenea: capsalidae). | attachment-inducing capacities of skin epithelial extracts of yellowtail, japanese flounder and red sea bream on oncomiracidia of the monogenean benedenia seriolae were examined. clear differences were not detected in the capacity among the fish species, although b. seriolae infects only yellowtail and its congeners in seriola. this suggests that either the capacity is not host specific or host-specific attachment-inducing capacity cannot be detected by the assay method. further, the attachment- ... | 2002 | 11835978 |
| benedeniine capsalid monogeneans from australian fishes: pathogenic species, site-specificity and camouflage. | there are about 70 species of capsalid monogeneans in the benedeniinae worldwide but only about half are described from the diverse fish fauna in the pacific ocean. up to 1992, only five species of benedeniines were known from australia. two potentially destructive species of benedeniines, benedenia seriolae from seriola lalandi and b. sciaenae from argyrosomus hololepidotus from temperate australian waters, are new host and geographic records for these monogeneans. a survey of some fishes from ... | 1996 | 8960215 |
| the complete mitochondrial genome of an ectoparasitic monopisthocotylean fluke benedenia hoshinai (monogenea: platyhelminthes). | an exponential growth of mitochondrial genome information has brought significant progress in understanding the organismal phylogeny and mitochondrial genome evolution for many metazoans including platyhelminth groups. in this study, we determined the complete mitochondrial genome sequence for benedenia hoshinai, an ectoparasitic monogenean species, and compared it with its congener benedenia seriolae. the complete mitochondrial genome is 13,554 bp in length and contains 12 protein-coding genes ... | 2012 | 22545965 |
| quantitative trait loci (qtl) associated with resistance to a monogenean parasite (benedenia seriolae) in yellowtail (seriola quinqueradiata) through genome wide analysis. | benedenia infections caused by the monogenean fluke ectoparasite benedenia seriolae seriously impact marine finfish aquaculture. genetic variation has been inferred to play a significant role in determining the susceptibility to this parasitic disease. to evaluate the genetic basis of benedenia disease resistance in yellowtail (seriola quinqueradiata), a genome-wide and chromosome-wide linkage analyses were initiated using f1 yellowtail families (n = 90 per family) based on a high-density linkag ... | 2013 | 23750223 |
| the complete mitochondrial genome of neobenedenia melleni (platyhelminthes: monogenea): mitochondrial gene content, arrangement and composition compared with two benedenia species. | the complete mitochondrial (mt) genome sequences of neobenedenia melleni were determined and compared with those of benedenia seriolae and b. hoshinai. this circular genome comprises 13,270 bp and includes all 36 typical mt genes found in flatworms. total at content of n. melleni is 75.9 %. atg is the most common start codon, while nad4l is initiated by gtg. all protein-coding genes are predicted to terminate with tag and taa. n. melleni has the trnr with a tcg anticodon, which is the same to b. ... | 2014 | 25024046 |
| praziquantel delivery via moist pellets to treat monogenean parasites of yellowtail kingfish seriola lalandi: efficacy and feed acceptance. | praziquantel (pzq) is registered for oral use against benedenia seriolae infecting seriola spp. in japan, but its bitter taste causes poor palatability. incorporating pzq in a moist pellet may help mask the flavor to improve intake. altering delivery, however, may influence efficacy. we assessed the minimum effective concentrations of pzq in moist pellets delivered by intubation for the monogeneans zeuxapta seriolae and b. seriolae infecting yellowtail kingfish seriola lalandi in flow-through ta ... | 2016 | 27786158 |
