Study On Ecology Of Marine Fouling Organisms In Cage-acquaculture Areas, Tong'an Bay, Xiamen

From March 2003 to Febuary 2004, an annual panel test was carried out on the fouling community in cage-aquaculture area of Tong'an Bay,Xiamen as to study the ecology of fouling organisms and to provide the scientific data for antifouling measures in this area.Wherein,135 species had been recorded, which included 28 kinds of algaes and 107 kinds of animals. The dominant species were Ulothrix flacca (Dillw.), Enteromorpha prolifera, Ulva lactuca L., Codium fragile (sur.) Heriot, Tubularia mesembryanthemum, Perna Viridis, C.acherusicum, Balanus reticulatus Utinomi,Styela plicata, etc,.. Also the species, coverage area, bio-quantity and the composition of fouling community were recorded particularly. The fouling community in cage-aquaculture area of Tong'an Bay belonged to the kind that attached throughout the whole year and the attaching seasons of the main fouling organisms were during April to October. The Jacard Community Coefficient was adopted to measure the conform degree of fouling community on bottom panels and the results showed that the composition difference of the three kinds of panels related to the structure of attaching base.In terms of the species and attaching seasons of algaes, the three kinds of furface panels didn't showed the difference as the attaching base.This paper also discussed the reason of mud-accumulation and its impact on the composition of fouling community, and the ecological phenomenon of infesting and...
