Abstract :
The present study was conducted for identification and assessment biodiversity of Polychaeta of Mongoft Artificial Reef structures in BushehrProvince. At first, 3 stations were selected. Seasonal samples were collected in spring and summer 2009, with 3 replication by diving operations, using Quadrates from each station was done. In total 7 species of Polychaeta were identified. Maximum frequency of Polychaeta, 644.64 n / m2, in the spring and the minimum number of 204 was recorded in summer. Results showed that Nereis sp. with 277.44 n / m2 (32.69 %) in the seasons and sampling stations was the most abundant. ANOVA results identified significant differences between the number of Polychaeta of the two seasons (P<0.05). In review of the biological indices, greatest Shannon diversity index was in station 1 in the spring with the amount of 1.83 and smallest Shannon diversity index in to the station 1 was in the summer with the amount of 0.50 has been. Indices were compared to determine that spring was diversity more diverse than summer. Considering the values obtained, biological indices it can be concluded that the region is exposed to stress, and it can affect the diversity of benthic fauna.
