| The frequency and distribution of benthic species in the south east coast of Caspian Sea (proposed site for cage and pen culture) were studied. Sampling was carried out in 2 water depths (1, 5) meters and 12 stations were sampled in each depth using VanVeen sampler. Totally, 11 taxa were identified: Pyrgulidae,Ampharetidae, Neritidae, Nereidae, Cardidae, Gammaridae, Naididae, Balanidae, Foraminifera, Ostracoda and Cumaceae. The most abundant taxa were Gastropoda (66.36%), Foraminifera (15.66%), Polychaeta (14.09%) and Bivalvia (1.65%) respectively. The maximum and minimum biomass was 164.1 g/m in summer and 6.56 g/m in spring. Depth, substratum, season, season-depth interaction, season- substratum –depth interaction had significant effects on biomass and had no significant effect on abundance. |
