Evaluation of water temperature in the Bocegaj brook and in the Kolíňany pond in terms of fish life

Abstract

brook, in the south by a 3 rd class road, which connects Beladice and Hosťová. In the north and the south, the border is formed by the top parts of hills. Neighboring villages are Žirany, Jelenec, Pohranice, Čeľadice and Hosťová. The area is a part of the lucerne – barley – wheat region. Cereals such as barley, wheat and fodder predominate in crop production. The village is an important wine region. The total area of the agricultural land fund in the During 2014, water temperature of the Bocegaj brook and the Kolíňany pond and its impact on fish life were monitored. Water sampling was carried out at regular monthly intervals, in the period from January to October, from six sampling points. The four sampling points were located directly on the water surface of the pond, the last place being the outlet from the pond. In this time horizon, all four seasons alternated, which was also reflected in the change of the water temperatures. The lowest average value of water temperature was recorded in January (0.5 °C) and the highest in June (19.23 °C). The maximum values of water temperature depending on the sampling point during the monitored period were found in the open water area of the pond.
