A river is an ecosystem where fish fauna represents important structural element. To re-establish connectivity, it imperative to allow movement between functional habitats. Due the hydromorphological complexity of large anthropized rivers and lack study techniques that can be used in such environments, relevant data with regard ecology are scarce. On River Meuse, Belgium, at a point 323 km upst...
In the present investigation, co-invasion of Lernaea parasite is reported in some fish species, collected from the Kor River Basin (Dorudzan Reservoir and Kor River), Southwest of Iran in 2010 and 2011. Lernaea cyprinacea parasites were isolated from the external surface of eye, lips, gills, nostrils, fins, operculum and body of Alburnus mossulensis, Capoeta aculeata, Capoeta saadii (all nativ...

This is a review on fish genetics research in Croatia and former Yugoslavia, based on the analyses of all the articles published in four main journals (Ribarstvo Jugoslavije, Morsko ribarstvo, Ichthyologia and Acta Adriatica) since 1945 till disintegration of Yugoslavia in 1991. Most of the papers cover the fields on cytogenetics and hybridization (24 and 13 respectively). Eight papers were on ...
Taxonomic studies on freshwater fishes of Iraq were reviewed. Considerable differences in number species that have been recorded Iraqi noticed, the ranged from 44 to 70 species. The difference might be due recording synonyms or incorrect records. continuous record new various periods may contributed such variation. Thirty eight species, mainly cyprinids, fell into disagreement category. A final...
Four hundred Gyrodactylus species have been formally described, but the estimated number of species in this fish ectoparasite genus of Monogenean Platyhelminthes is more than 20,000. The unusually high species richness has lead to the hypotheses of speciation and adaptive radiation via host switching. These hypotheses were tested by reconstructing a molecular phylogeny for the subgenus G. (Limn...
