Protozoa of Lough Neagh,Northern Ireland,UK

This paper made the first records of taxa composition of protozoa in Lough Neagh,the largest freshwater lake in British Isles. One hundred and eight species(genus)were identified from the examinations of approximately 150 PFU artificial substrates and various types of natural substrate from May to December, 19g2. Of 108 species or genus,30 core species were found on PFU substrate and 17 on natural ones.The ecological characteristics of protozoa were studied by showing the variations of species richness and individual abundance as a function of season or water temperature.Protozoa on PFU were compared at two sampling stations as well.
