Leuciscus leuciscus (L.) z rzeki Solinki w Bieszczadach (Pisces, Cyprinidae)

Gonadogenesis in chub Squalius (Leuciscus) cephalus (L. 1758).

The chub is an opportunistic, rheophilic cyprinid species and popular gamefish distributed throughout almost all of Europe, South Caucasus and part of Anatolia. It is most abundant in small rivers and large streams. The process of anatomical and cytological differentiation was analyzed in chub gonads. Material used in the study was derived from artificial spawning of adult individuals caught in...

Use of the chromosomal co-location of the minor 5S and the major 28S rDNA as a cytogenetic marker within the genus Leuciscus (Pisces, Cyprinidae).

The chromosomes of three species from the genus Leuciscus (the ide L. idus, the European chub L. cephalus and the common dace L. leuciscus) were examined with the FISH technique for 5S and 28S rDNA probes. The analysis showed that among the three examined species, 5S rDNA signals were located on two large and four small subtelocentric chromosomes in L. leuciscus, on one large and five small sub...

Metal Concentrations in Chub, Leuciscus Cephalus, from a Submontane River

In many aquatic environments elevated levels of trace elements occur due to anthropogenic activities. Water organisms can be precise indicators in estimating the status of pollution of water environments. Among them several species of fish have been widely used (Håkanson 1984, Chevreuil et al. 1995, Andres et al. 2000, Falandysz et al. 2000, Perkowska and Protasowicki 2000, Řehulka 2001, Wagner...
