THE INVENTORY OF FISH FROM THE NATIONAL PARK CĂLIMANI - DIVERSITY AND DISTRIBUTION
Journal Title: Current Trends in Natural Sciences - Year 2017, Vol 6, Issue 11
Abstract
In the Călimani National Park, the inventory of the fish species of community importance, carried out in 2013 through a project from the Sectoral Operational Program for Environment, revealed that there is only one species of community interest in the park, namely Cottus gobio (bullhead). This is a normal fact given that the site is located at altitudes ranging from a maximum of 2083 m to a minimum of 470, and most of the waters are represented by alpine creek. In the all four fishing campaigns, 30 tributaries were investigated and a total of 220 individuals were fished out of which: 156 individuals of river trout (Salmo trutta fario), 9 individuals of common bullhead (Cottus gobio), 52 individuals of rare bullhead (Cottus poecilopus), 2 individuals of grayling (Thymallus thymallus) and 1 individuals of minnow (Phoxinus phoxinus). Ihtiofauna has a very low diversity, being constantly represented by one species of fish, Salmo trutta fario, which is well suited to the conditions of the creek situated on slopes of 1-3 m/km. Thus, out of the 30 investigated water courses, Salmo trutta fario is present in 17 water courses. Instead of this, Cottus gobio, a species of fish of community importance, has a very low presence on the territory of Calimani National Park, this situation is, to some extent, inadequate.
