Zooperiphyton on Anti-Fouling Coatings and Changes of Its Coenotic Structure

Abstract

The features of the zooperiphyton communities' forming on experimental substrates - protective coatings with antifouling properties, based on industrial alkyd enamel PF-167 modified by cationic biocides 1-dodecylpyridine oleate and 1-dodecylpyridinium bis(2-ethylhexyl) phosphate in the bay of the Kaniv reservoir (the Dnieper river) have been studied. Some features of successional changes in the Zebra mussel and Bryozoans' (pearlwort) communities were discussed. On the contrast to the previous years, when the water temperature in August (time of high development of bryozoan colonies) was lower, the continual succession of communities with <i>Dreissena'</i>s dominance was not interrupted by the bryozoan's development. The protective coatings containing 8% of cationic biocides demonstrated high antifouling activity. In this study, no connections between the cenotic structure and nature of antifouling coatings were found.
