Abstract

The Ealga project (RNM 1235) has addressed the cultures in the field of severaledible macroalgal species of interest for the food industry, particularly Gracilariopsislongissima and Chondracanthus teedei. The research has been carried out in Cadiz Bayand in earthen ponds also used for marine salt extraction, and included the cultivation ofmacroalgae in ropes under different environmental variables (season, seedling densitiesand flow). The effect of irradiance, temperature, salinity and nutrient levels in the growthrate of these species has also been tested in laboratory cultures, rendering thallus with verydifferent nutritional properties and colors, which can be of interest for the food industry.The project also include numerous activity for the dissemination of the use of macroalgaeas a food resource. The promising results pointed out the posibilities of macroalgalcultures in earthen ponds of Cadiz Bay, especially as part of future initiatives based onintegrated multitrophic aquaculture.
