Studies on the Ecology of Fouling Community in Daguanban Reclamation Area of Luoyuan Bay

摘要

The test panels have been set for one year in the waters of Daguanban reclamation area of Luoyuan Bay to investigate the ecology of fouling community. 39 species of animals and 8 species of algae have been recorded during the investigation. The main period of settlement extends from May to October. The peak periods of biomass and covered area rate of the panels have been observed from Juneto September Balanus reticulatus, Bugula neritina, Molgula manhattensis, Tubularia mesembryanthemun and Enteromopha interstinalis are the dominant species in the fouling community. Species diversity index, species richness, species evenness and environmental factors are determined, the results of which indicate that water flow speed is the most important factor influencing the species and quantity composition of the fouling community.As to the mariculture production in the reclamation area, the main harmful period ranges from June to September.
