| 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 |
| towards the conservation of crucian carp carassius carassius: understanding the extent and causes of decline within part of its native english range. | the extent and causes of crucian carp carassius carassius decline were assessed during an initial study of c. 25 ponds in north norfolk, eastern england, u.k., which was then replicated (a validation study) on another c. 25 ponds in an adjacent area. of these ponds, c. 40 are known to have contained c. carassius during the 1970s-1980s. in the initial and validation studies, c. carassius were found in only 11 of these ponds, yielding declines of 76% (five of 21 ponds) and 68% (six of 19 ponds), r ... | 2011 | 22136242 |
| 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 ... | 1994 | 7706678 |
| seasonal development and pathological changes associated with the parasitic nematode philometroides sanguineus in wild crucian carp carassius carassius (l.) in england. | pathological changes associated with the parasitic nematode philometroides sanguineus (rudolphi, 1819) are described for the first time from observations of infections in wild crucian carp carassius carassius (l.) in england. the damage caused by p. sanguineus was influenced strongly by host size, parasite development and the seasonal migrations of female nematodes within host tissues. male and unfertilized female nematodes located on the swim-bladder wall caused only minor, localized changes. i ... | 2012 | 22824259 |
