Abstract :
The present study aimed at identification and assessment of biodiversity of crustacea of Mongoft Artificial Reefs in BushehrProvince and was conducted in 2009. Seasonal samples were collected in spring and summer, with 3 replication in 3 stations by diving operations , using a quadrate with dimensions of 35 × 35 cm. In total 10 species of crustacea identified were related to two orders Decapoda and Cirripedia. Barnacles with 1508 number per m2 (52.8 %) had the highest frequency. Maximum frequency of crustacea, 768 / m2 , in spring and the minimum number of 211 was recorded in summer. Results showed that Palaemonidae family of Decapoda with 761 n / m2 ( 26.6 % ) in the seasons and sampling stations was more abundant compared to other species. ANOVA results identified between the two seasons numbers of Custacea. ( P<0.05). In review of the biological indices, highest Shannon diversity index value was in station 1 in spring with the amount of 1.80 and lowest Shannon diversity index value in the station 3 in summer with the amount of 0.99. Indices used to determine that spring species diversity was more than summer. Considering the values obtained for biological indices it can be concluded that the region may be exposed to stress.
