    Kappaphycus farming is being widely adopted by floating bamboo raft method in Tamil Nadu coast (Plate 1). In few places tube net and monoline culture technique is also being practiced for seaweed cultivation. Floating raft is made of bamboo with 12’ × 12’ for mainframe and 4’ x 4’ for diagonals. In each raft, 20 polypropylene-twisted ropes are used for plantation. Around 150 – 200 grams of seaweed fragments are tied at a spacing of 15 cm along the length of the rope. A total of 20 seaweed fragments can be tied in single rope. The total seed requirement per raft is 60 – 80 kg. Fish net of 4m x 4m size is tied at the bottom of the raft to avoid grazing. In normal season, a cluster of 10 rafts are positioned in the near shore area of 1.0 to 1.5 m depth using a 15 kg anchor.
