Neries upės ichtiofaunos lašišinių ir salačių žuvų analizė / Analysis of Ichthyofauna salmon and asp fish of Neris RiverPabrieža, Marius 15 June 2009 (has links)
Darbo tikslas: atlikti Neries upės ichtiofaunos rūšinės sudėties, gausumo ir pasiskirstymo analizę pagal turimas ataskaitas bei literatūros šaltinius. Darbo objektas: Neries upė. Darbo metodai: darbas atliktas panaudojant literatūroje skelbtas pagal temą metodikas bei atlikta turimų duomenų analizė. Kadangi ichtiofaunos (nektono) rūšinė sudėtis esminiai skiriasi ne tik sistematiniu požiūriu, bet ir fiziniais parametrais jie buvo tiriami pagal sekančias metodikas skirtas Neries upės ichtiofaunai. Detaliau buvo analizuojama vykstantys pokyčiai tarp atskirų hidrobiontų grupių. Darbo rezultatai: Upės nektoną dažniausiai sudaro žuvys. Jų įvairovė gana didelė. Dalis organizmų gyvena priekrantėse, kiti laikosi prie dugnų, dar kitos – vandens sluoksnyje. Neries upės nektoną sudaro lašišos, upėtakiai, šlakiai, salačiai ir kt. žuvys. Upių žuvingumą lemia natūralūs ir antropogeniniai veiksniai. Neries hidrobiontus labiausiai įtakoja vandens tarša, kuri yra ir organinė ir cheminė. / The aim of the thesis: to perform analysis of ichthyofauna of Neris river on the basis of existing sources of literature and scientific reports of the Institute of Ecology. The object of the thesis: Neris river. The work methods: the methods published in the literature, corresponding to the topic of the thesis, were applied in the work, and analysis of the existing data was performed. As species composition of ichthyofauna (nekton) differs essentially not only in the systematic respect, but also by physical parameters, they were investigated with application of the following parameters intended for ichthyofauna of Neris river. The changes occurring between different groups of hydrobionts were analysed in more detail. The results of the thesis: Nekton of the river consists mainly of fish. Their variety is rather large. Some organisms live in the littoral area, some at the bottom, others in the water layer. Nekton of Neris river consists of salmon, trout, sea trout, asp, etc.. Quantity of fish is determined by natural and anthropogenic factors. The hydrobionts of Neris river are mainly influenced by water pollution, both organic and chemical.
