the distribution and host range of species of the blood fluke sanguinicola in british freshwater fish.the distribution of host range of sanguinicola armata, s. inermis and s. volgensis in british freshwater fish are described. s. inermis has been recorded in carp cyprinus carpio, crucian carp carassius carassius and tench tinca tinca in southern, central and eastern england and in koi carp imported from japan. s. armata has been detected in pike esox lucius and tench and s. volgensis has been found in chub leuciscus cephalus, dace leuciscus leuciscus, perch perca fluviatilis, roach rutilus rutil ...19947706678
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.199910613531
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 ...200314735920
the presence of eu priority substances mercury, hexachlorobenzene, hexachlorobutadiene and pbdes in wild fish from four english rivers.since 2007 about 200 to 300 fish per year--generally roach (rutilus rutilus) also a few bleak (alburnus alburnus) and eels (anguilla anguilla)--have been collected from a number of english river sites and stored at -80°c to build up a fish tissue archive as a resource for the monitoring of pollutants. some of the fish from the fish tissue archive from the years 2007-2011 were analyzed for substances in current and proposed european legislation regarding environmental quality standards (eqs) in b ...201323747559
endocrine (sexual) disruption is not a prominent feature in the pike (esox lucius), a top predator, living in english waters.the high incidence of intersex roach (rutilus rutilus) in some united kingdom rivers that has been associated with exposure to sewage treatment works (stws) effluent led us to hypothesize that top predator fish also may be affected by estrogenic chemicals, because they are likely to bioaccumulate lipophilic compounds through a predator-prey relationship. to investigate this possibility, pike (esox lucius) were sampled both upstream and downstream of stws and then examined for total estrogenic ac ...200516117120
myxobolus buckei sp. n. (myxozoa), a new pathogenic parasite from the spinal column of three cyprinid fishes from the united kingdom.myxobolus buckei sp. n. is described from the spinal column of leuciscus cephalus (l.), rutilus rutilus (l.) and abramis brama (l.) from freshwater rivers in the north of england. the plasmodia develop within the remnants of the embryonic notochord in the intervertebral spaces. the spores are large, measuring (in microm) 14.0 +/- 0.7 x 11.5 +/- 0.6 (mean +/- sd), smooth, round to ellipsoid in valvular view with several sutural edge markings. the polar capsules are pyriform and of equal size, mea ...200314971593
