prevalence and intensity of haemobaphes diceraus (copepoda: pennellidae) from shiner perch, cymatogaster aggregata (embiotocidae). | the prevalence and intensity of the hematophagous pennellid copepod haemobaphes diceraus were monitored over a 10-mo period in shiner perch cymatogaster aggregata at pipers lagoon, nanaimo, british columbia. the prevalence and mean intensity of metamorphosed adult female h. diceraus (n = 421) were 10.0% and 1.2 (+/-0.5 sd), respectively. the majority (97.9%) of infected fish had single infections, reflecting the possibility of intensity-dependent parasite-induced mortality, rejection of addition ... | 2002 | 12053967 |
a new species of loma (microsporea) in shiner perch (cymatogaster aggregata). | loma embiotocia n. sp. is described from the gills of shiner perch (cymatogaster aggregata) from waters off vancouver island, british columbia, canada. highest prevalence at a site was 15% and greatest intensity was 583 xenomas per fish. xenomas averaged 0.13 mm in diameter (0.06-0.16 mm) and contained ovoid spores 4.8 x 2.6 (4.0-5.0 x 2.0-3.0) microns. sporogonic stages were dispersed throughout the xenomas. the xenoma wall was smooth lacking invaginations into the cyto plasm: sporoblasts were ... | 1997 | 9105314 |
