In this study we have performed a comprehensive genotoxicological survey along the 900 rkm of the Sava River. In total, 12 sites were chosen in compliance with the goals of GLOBAQUA project dealing with the effects of multiple stressors on biodiversity and functioning of aquatic ecosystems. The genotoxic potential was assessed using a complex battery of bioassays performed in prokaryotes and aq...

The large-scale hybridization of fishes the subfamily Leuciscinae in subordinate systems Dnipro River basin is presented by data on two pairs species, roach Rutilus rutilus × bream Abramis brama, and bleak Alburnus alburnus rudd Scardinius erythrophthalmus. occurrence F1 hybrids are confirmed with allozyme spectra morphological characters series samples. A complete morphometric analysis charact...

 This study was carried out to investigate occurrence of parasite in selected cyprinid fish species in Gandoman Lagoon, in the vicinity of Gandoman City, Chaharmahal & Bakhtyari Province. A total of 90 fish specimens including Cyprinus carpio, Carassius auratus gibelio, Capoeta aculeata , C.damascina, Chondrostoma regium and Alburnus alburnus from Gandoman were examined during spring and summer...

Hybridization between native and nonnative fish species is a major conservation issue, especially in ecosystems with high levels of endemism, such as Iberian streams. To date, hybridization the invasive bleak Alburnus alburnus has been reported for chub Squalius alburnoides S. pyrenaicus scattered locations only. However, spreading region, potentially increasing risks other species. gather more...

Diplostomum is a taxonomically problematic genus of trematodes, with many members harmful at the metacercarial stage to fish in aquaculture. We found metacercariae eye vitreous humor rudd, Scardinius erythrophthalmus; bleak, Alburnus alburnus; and roach, Rutilus rutilus, Karelia (Russia) identified them as numericum based on combination morphological ecological data. Previously, D. was thought ...

Experiments were conducted to assess the pathogenicity of 2 'atypical' Aerornonas salmon~cida strains solated from ulcerated flounders Platichthys flesus for this species, rainbow trout Oncorhynchus mykiss, roach Rutilus rutilus, and bleak Alburnus alburnus. The pathogenicity of the strains was evaluated by 3 challenge methods: intraperitonea] (i-p.) injection, subdermal (S d . ) injection, and...

The Common Krait (Bungarus caeruleus) shares a distribution range with many other ‘phenotypically-similar’ kraits across the Indian subcontinent. Despite several reports of fatal envenomings by Bungarus species, commercial antivenoms are only manufactured against B. caeruleus. It is, therefore, imperative to understand genetically distinct lineages kraits, compositional differences in their ven...
