Producción, eficiencia de biofiltración y composición nutricional de las macroalgas Ulva rigida y Gracilaria cornea cultivadas en efluentes de cultivos marinos

Abstract

This work reviews he yield, biofiltering efficiencies and nutritional composition of Gracilaria cornea J. Agardh and Ulva rigida C. Agardh cultivated with marine fish waste waters. Growth rate and total production reached values of 10.24 2.52 %d'l and 70.04 * 24.68g DW m" d" for U. rigida and 5.08 * 2.01 %d.' and 43.74 * 19.43 g DW m-' d.' for C. cornea. The ammonia removal eníciencies were 74% and 6 1% for U. rigida and C. cornea repectively. The suitability of the seaweed produced as a feed for abalone is discussed in tenns of protein, lipid and carbohydrate wntent.
