Fish scale shape analyses: in mirror of phylogenetics
Several studies proved that fish scale shape is suitable for species identifcation, and for population level discrimination as well. There is lack of information about how the scale shape refer to the taxonomic position of a certain species. For this reason the scale shape of 10 fish species (roach Rutilus rutilus, chub Squalius cephalus, gibel carp Carassius gibelio, razorfish Pelecus cultratus, bleak Alburnus alburnus, carp Cyprinus carpio, topmouth gudgeon Pseudorasbora parva, perch Perca fluviatilis, pikeperch Sander lucioperca, rudd Scardinius erythrophthalmus), inhabiting the catchment of Lake Balaton was compared to their phylogenetic positions derived from COI sequences, available i…
The distribution patterns, risk and potential effect of non-indigenous fish species of Hungarian waters
Translocation and introduction of non-indigenous species might be considered as one of the least reversible human induced changes in nature. The background factors of a successful biological invasion are diverse; and the complete eradication of established invasive species seems practically impossible. The aim of our presentation is to (1) revise the trends and spreading mechanisms of non-indigenous species; (2) assess the potential ecological risk of new species in the catchment basin of a shallow lake (Lake Balaton, Hungary) and (3) to analyze the local and regional factors affecting the distribution patterns of gibel carp (Carassius gibelio), an effective invasive species of the region, …
