Ichtiofauna Bieszczadzkiego Parku Narodowego: Skład gatunkowy, struktura i zagrożenia
Journal Title: Roczniki Naukowe Polskiego Związku Wędkarskiego - Year 2015, Vol 28, Issue
Abstract
The aim of the study was to present the species composition and ichthyofauna structure of selected streams of the Bieszczady National Park. The study also tries to identify the main threats to the fish fauna of that area. The ichthyofauna consists of 15 fish and lamprey species. In terms of abundance, it was dominated by common minnow, Siberian sculpin and brown trout. In terms of biomass, it was dominated by brown trout and European grayling. The most important forms of anthropopressure are the impact of the Solina Dam Reservoir and poaching. There are also several point sources of pollution in the upper San River catchment. Streams of the Bieszczady National Park retain their unique natural values. Their almost natural character allows to determine sites that can be a reference for other Carpathian tributaries of the Vistula River.
