Abstract
Study of the diversity of rotifer in fishery ponds from Amarapura Township near Taungthaman Lake was carried out from December 2013 to March 2014. The rotifer samples were collected by plankton nylon net with a mouth diameter of 12 cm and 50 μm mesh size. Field sampling were conducted bimonthly from the two sampling ponds. A total of 16 species of freshwater rotifers were recorded. Brachionus angularis was the most dominant species and second dominant species was Polyarthra vulgaris in both ponds. The least dominant species was Brachionus forficula in pond I and Filinia terminalis in pond II. The Shannon- weaver diversity index value (H’) ranged from (1.44-1.87) in pond I (1.58-1.95) in pond II. In this result, although H’ value were no significant differences between these two ponds, the relative abundance of the rotifer population is higher in pond I (69.36%) than pond II (40.20%).
