| isolation of a rhabdovirus during outbreaks of disease in cyprinid fish species at fishery sites in england. | a virus was isolated during disease outbreaks in bream abramis brama, tench tinca tinca, roach rutilis rutilis and crucian carp carassius carassius populations at 6 fishery sites in england in 1999. mortalities at the sites were primarily among recently introduced fish and the predominant fish species affected was bream. the bream stocked at 5 of the 6 english fishery sites were found to have originated from the river bann, northern ireland. most fish presented few consistent external signs of d ... | 2003 | 14735920 |
| gyrodactylus sommervillae n. sp. (monogenea) from abramis brama (l.) and rutilus rutilus (l.) (cyprinidae) in oxfordshire, uk. | gyrodactylus sommervillae n. sp. (monogenea) is described from the skin, fins and gills of abramis brama (l.) and rutilus rutilus (l.) from blenheim palace lake, oxfordshire, uk. g. sommervillae n. sp. closely resembles g. aphyae malmberg, 1957, g. kearni ergens, 1990 and g. lamberti ergens, 1990 in the approximate shape of the marginal hook sickle and the anchors, but can be separated on the precise shape of the marginal hooks and the ventral bar. | 1999 | 10613531 |
