Seasonal dynamics of fish assemblage in a pond canal

Popis výsledku v původním jazyce

The annual dynamics of fish assemblage in a pond canal of South Moravian pond aquaculture facility was studied to reveal potential assemblage effects on pond stocks and vice versa. The species richness of fish assemblage and seasonal dynamics of its development were dependent upon the fish stock of interconnected ponds, which contributed to a considerable increase of commercial fish species occurrence. Using a seasonal parameter, season proved to have a major impact on fish assemblage dynamics (r = -0.71, p < 0.001). Spring samples were dominated by fishes of aquaculture origin (mainly Cyprinus carpio). Occurrence of several fish species originating from the wild (bleak, Alburnus alburnus, chub, Leuciscus cephalus and roach, Rutilus rutilus) was also reported. The pond canal was found to be an important reservoir site of persistant survival and subsequent spreading of some undesirable alien fishes like topmouth gudgeon (Pseudorasbora parva) and gibel carp (Carrasius auratus).
