Summary: The physiological variation of seaweed edible Palamaria with regard to the content of nutrieres of the marine environment, and environmental factors that vary in the coastal ecosystem was studied in two populations of northern Spain. The availability of nitrogen and phosphorus, light, and the waves showed an intimate synch with the seasonal variation of physiological status and nutritional value of individuals. In terms of high availability of nitrogen and phosphorus, high waves and low radiation, these nutrients stored in the thallus in the form of reserves. It also noted evidence that the kinetics of uptake of these nutrients are biphasic, allowing the acquisition of nutrients to the entire range of concentrations observed in the field. This species also showed a marked metabolic adaptation to the conditions of light and shade where it grows in their natural habitat. Plants light showed higher values of carbon, coinciding with a dilution of the compounds rich in nutrients talo, at the end of the summer. The crop vertical ropes P.palmata was adequate to the conditions of the northern coast of Spain. The technology was transferred to a newly-created company to promote the cultivation of macroalgae in our country.
