THE BIOLOGY OF SLIME FILMS. 2 PARTS

The first of these two articles is devoted to discussing the green alga Ulothrix which repeatedly occurs on submerged test panels. Although closely related to Enteromorpha, Ulothrix reacts very differently to antifouling compositions in that it is resistant to organotin antifouling paints. The structure and spore settlement of Ulothrix are described. It is a very simple plant, consisting of single hairlike filaments made up of cells joined end to end in chainlike fashion. The filaments can grow outwards from the slime film to form a dense mat up to 1 cm thick, and it can effectively reproduce itself by the production of millions of spores. Part 2 looks more closely at the development of slime films on submerged surfaces coated with organotin antifouling compositions. Panels coated with an experimental series of organotin antifouling paints were exposed on a submerged raft, and removed at weekly or monthly intervals over a period of nine months. For comparative purposes, a non- toxic border was left around the area with antifouling paint. Detailed examination of the fouling community on the central experimental areas of the plates after 20 weeks submersion revealed that the main fouling growth was due to the diatom Achnanthes.
