Abstract

Abstract - A new flotaton model for the experimental culture of macroalgae Kappaphycus alvarezii (Doty) Doty ex P.C. Silva is described and illustrated. The ellipsis-shaped 90L apparatus is made of medium density virgin polyethylene, measuring 2000mm long x 300mm wide x 200mm high, and weighing 9kg. The device has been successfully tested in the litoral region
of the state of Santa Catarina, Brazil, throughout the experimental period. Contrastingly to traditional models available on the market, with their instability in strong sea currents, the current model is an alternative to enhance algae-mollusks integrated culture, by providing stability to culture structures. It may also serve as a spacer and support for mooring of double long lines.
