Dissertação de mestrado, Biologia Marinha, Faculdade de Ciências e Tecnologia, Universidade do Algarve, 2017Waste water from intensive aquaculture can cause eutrophication of coastal waters and subsequent negatively impact downstream biological communities. The use of macroalgae as active biofilter optimizes the reduction of the dissolved nutrient loads in aquaculture effluents. Ulva species with their high growth rates and tissue nitrogen contents are very good candidates for bioremediation besides having an active role on carbon sequestration. This study identified the Ulva sp. cultivated in earth ponds facing the Ria Formosa lagoon (South Portugal), and assessed the biomass production, the SGR (specific growth rate) and CO2 uptake perfor...
