Avila, M., Nuñez, M., Plaza, H. & Pavez H. Unidad Técnica de Algas, Instituto de Fomento Pesquero, P.O.Box 665. Puerto Montt, CHILE Sarcothalia crispata and Gigartina skottsbergii are the most important species in volume and value for the domestic production of carrageenan in Chile. Harvesting pressure has been intensified during the last years decreasing the biomass of the natural beds. Because of the importance of this seaweed resources three restoration techniques were develop and assayed in two localities in southern Chile. Densitiy and growth of the fronds was measured in time. Results show that higher densities for Sarcothalia crispata were obtained in autumn through direct seeding. For Gigartina skottsbergii higher densities were in winter also through direct seeding. Methods develop to enhance Sarcothalia and Gigartina beds are discussed.
