Full Length Research Paper
Abstract
In this research, sampling was done from the biofouling organisms of piles of Deilam port from Autumn 2009 to Spring 2010. Two stations were chosen and samples were taken from three zones: super tidal zone, inertial zone and sub-tidal zone in 1 × 1 m2. At the same time, the environmental factors (pH, salinity, conductivity, temperature) were measured. Ecological indices such as Shanon, species richness, Simpson and evenness were calculated. Results showed that biofoulings belong to 4 phyla, 5 classes, 9 orders, 9 families, and 10 genera. The identified species are as follows: Palletoida profunda, Barbatia obliguata, Serpula sp., Nereis sp., Saccostrea cucullata, Thais mutabilis, Balanus amphitrite, Trochus radiatus, Natica vitelius, Antopleura sp. Barnacle (B. amphytrit) was the dominant species in all 3 tidal zones. Results of variation analysis between diversity and environmental factors were significant only for temperature (-0.349).
Key words: Biofouling organisms, taxonomic identification, ecological indices, Deilam port.
