Abstract

The frequency and distribution of meiobenthoses in northern Creeks of the Bushehr Province during autumn2000- Summer200I were studied for determining the condition of sea sediments using seasonal sampling.
Samplings were carried out in 10 stations from Doube Creek to Bandar Genaveh Creek as well as a control station in the Persian Gulf. 
Totally, 4 taxa of meiofauna were identified that Ostracoda and Gastropoda with 29% and 18% had the maximum and minimum percent of abundance, respectively. The maximum percent of abundance in station No.10(control station at sea) with 20735 n/m2 and the minimum abundance in station No.2 (Creek of Farake)with 5320 n/m2 were observed. The maximum abundance of meiobenthose in spring with 167603 n/m2 and the minimum abundance during winter with 61365 nlm2 were determined. In addition, grain size, soil texture and total organic matter (T.O.M) of sediment in 10 stations were analyzed. Results showed that station No.10 with 11.79% had the maximum percent of T.O.M while the minimum T.O.M (3.87%) in station No.4 (Gasir Creek) was observed. The correlation of sampling station based on the abundance of meiobenthose was also analyzed.
