Abstract

The second paper of this series reports the results of comparative studies on the marine antifouling properties of a range of six copper and copper-alloy materials, using settlement and growth of a copper-tolerant strain of the marine-fouling algaEctocarpus siliculosus as criteria. Samples of ordinary copper, arsenical copper, copper-nickel 90/10, copper-nickel 70/30, aluminium brass and aluminum bronze were preincubated in sterilized seawater medium under laboratory conditions and then used to follow the early stages of spore settlement and subsequent development of colonies of the alga in the culture system by both light and scanning electron microscopy. The results of this bio-assay are compared with other published information relating to the long-term antifouling properties of these materials in trials at sea.
