Does anyone know which kind of natural surfaces stimulates algal propagules (particularly red algal spores) to settle on a solid surface in marine/brackish condition. There are numerous papers dealing with marine antifouling aspect of several coatings, but how to lure benthic organisms to attach on the submerged surfaces.
Any references etc are welcome
If you have 2x spores in mind, then dead corals, coralline stones, empty shells of bivalves especially pearl oyster are some of the good materials for their settlement. If the spores are haploid, the same materials along with hard rock surface will also give the same result. X spores will not attach to submerged surfaces, but as they float on surface of water, they settle on whichever objects which the first & the last waters of the incoming & outgoing tides sweep over them.
Dear Chandravadan, Thank you for some clues.
Diploid tetraspores (2n) are in my mind to settle in North Atlantic. Perhaps, there are some special coatings which induce settlement/attachement of seaweed spores?
Hi
Two references that might be useful. the paper on Fucus settlement is a study of different rocky surfaces in the Baltic Sea.

Hi Lena, thanks for very useful papers, could You please send me your Fucus paper
Priit
Sorry I am on holiday and don´t have a copy scanned. So it will have to wait until start of august. you might try Torleif Malm the first author. Cheers Lena
