[Metazoan parasites of roach Rutilus rutilus (L., 1758), bream Abramis brama (L., 1758) and perch Perca fluviatilis L., 1758 from lakes of river Łyna watershed].
During the years 2004-2006 the parasitological autopsies of three species of fish: roach Rutilus rutilus (L.), bream Abramis brama (L.) and perch Perca fluviatilis L. from three lakes situated in warmińsko-mazurskie voivodeship were done. The aim of this study was comparable analysis of Metazoan parasite communities which occur in roach, bream and perch in three lakes of river Łyna watershed. T...
متن کاملExperimental demonstration of a behavioural modification in a cyprinid fish, Rutilus rutilus (L.), induced by a parasite, Ligula intestinalis (L.)
Behavioural changes in parasitized hosts have been experimentally investigated by comparing the swimming behaviour of roach, Rutilus rutilus, infected by the tapeworm Ligula intestinalis with that of uninfected roach when they were exposed to the same overhead heron stimulus. Before the stimulus was presented, infected fish swam close to the surface and uninfected fish were preferentially found...
متن کاملSome Aspects of Branchial Parasitism in Rutilus Rutilus (linnaeus, 1758) from Moara Domnească Lake
An environment intensively studied from many perspectives, through the efforts of an interdisciplinary team of biologists, ecologists, geneticists, chemists, pedologists, etc. is Moara Domnească agroecosystem. Located in the North-East of Bucharest, the Moara Domnească Lake is used for irrigation of the neighbouring agricultural areas and also for pisciculture (Stavrescu-Bedivan et al., 2011). ...
متن کاملSex and Sexual Ornamentation Associated with Survival of the Cyprinid Fish, Rutilus rutilus, under Disease Stress
By conveying information of disease resistance, sexual signals may be used as cues for adaptive mate choice. Here we report observations on survival of laboratory-maintained, wild-collected, sexually mature, ready-to-spawn cyprinid fish, Rutilus rutilus (roach), under accidental epidemic attributed to Flavobacterium psychrophilum, diagnosed using species-specific PCR. The fish were maintained i...
متن کاملFactors affecting between-lake variation in the occurrence of epidermal papillomatosis in roach, Rutilus rutilus (L.).
The theory of island biogeography predicts that the probability of a species occupying an island depends on a dynamic equilibrium between extinction and colonization. Epidermal papillomatosis is a disease manifesting as skin tumours on fish. We studied the factors affecting the occurrence of the disease in roach, Rutilus rutilus (L.), in 34 lakes. The results of discrimination analysis suggest ...
