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
