Collecting Localities: The coordinates of the stations in Aksu Stream Basin where the Oligochaeta samples were collected are as follows:

(45°57’989’’N-27°90’298’’E);

2-

Village

(45°67’784’’N-27°84’014’’E); 3- A¤lar Stream, ‹hsaniye Village (45°70’048’’N-27°79’353’’E); 4- Kavgac›lar Village (45°77’284’’N-27°80’596’’E); 5- De¤irmen Stream, Güloluk Village (45°84’621’’N-27°76’323’’E); 6- Aksu Stream, Karaöz Village (45°97’689’’N- 27°64’996’’E); 7- Boladin Stream, Karaöz Village (°45’89’54’N-27°67’705’’E); 8- Beldibi Stream, Karg› Village (46°05’510’’N-27°64’292’’E); 9- Isparta Stream, Afla¤›gökdere Village (46°33’404’’N-27°49’167’’E); 10- Aksu Stream (°46’37’584’N-27°53’155’’E).

Results and Discussion

The samples collected during the research period indicate the presence of 17 species of Oligochaeta:

(Michaelsen, 1901), Tubifex tubifex (Müller, 1774), Limnodrilus hoffmeisteri Claparéde, 1862, Limnodrilus udekemianus Claparéde, 1862, belonging to the family Tubificidae, Chaetogaster diaphanus (Gruithuisen, 1828), Nais pardalis Piguet, 1906, Nais variabilis Piguet, 1906, Nais communis Piguet, 1906, Nais bretscheri Michaelsen, 1899, Dero digitata (Müller, 1774), Aulophorus furcatus (Müller, 1774), Pristinella osborni (Walton, 1906), Pristinella jenkinae (Stephenson, 1931) and Stylaria lacustris (Linnaeus, 1767) belonging to the subfamily Naididae. The Table shows the distribution of the species identified in Aksu Stream Basin. In addition, some characteristics of the species are shown in Figure 2.

Although species richness was not high in the study area, the greatest number was at station 1 (7 species), followed by stations 2 (6 species) and 6 (5 species). Among these 3 stations, in Aksu Stream Delta (station 1) the abundance of Oligochaeta species was not high except for Stylaria lacustris. It was the most abundant Oligochaeta species observed during the study period at

Table. Composition and distribution of Oligochaeta species determined in Aksu Stream.
