The red macroalgae (Rhodophyta) are of great economic relevance in the world, being mainly cultivated for the preparation of nori leaves, so well-known in Japanese gastronomy. Nori is recognized for its health benefits, due to its high content of vitamins, minerals, and proteins. For this reason, the domestication of this group of macroalgae could be of great commercial interest for aquaculture companies in Peru, estimating profits of billions of dollars per year. The present study and the knowledge of the behavior of these microorganisms called “conchocelis”, has been essential for the domestication process of the species, which has started since the 17th century in Asian countries and, to date, is considered one of the most important industries. Porphyra sp. is a genus of red algae that has been reported in southern Peru, in the regions of Arequipa, Pisco and Ica and, to the north, in the Piura region. The objective of this work was to determine the optimum concentration of two commercial sources of essential nutrients: “Bayfolan®” and hydroponic solution “La Molina” A and B for the growth and development of the “conchocelis” phase of Porphyra sp. The aim is to contribute to the utilization of Porphyra species, encouraging the development of the southern region, Santa Elena de Paracas-Peru beach, either by supplying the local and national demand and/or by entering the international market. On the other hand, this work will complement recent genetic studies based on molecular markers of these red macroalgae; in addition, the reproductive biology, and its relationship with environmental factors Porphyra species. The results were obtained in its first stage (microscopic) known as filamentous endolithic growth of “conchocelis” in calcareous substrate settlement. There in vitro growth was analyzed in germination chambers programmed with a temperature of 15.03 °C, salinity 36.05 PSU, electrical conductivity 55.95 mS/cm, irradiance 15.93 micro moles. m-2 .s-1 and fertilizers “Bayfolan®” and Ay B la Molina hydroponic solution containing Nitrate (NO3 - ) and Phosphate (PO4 -3 ). The data in each experimental design were applied ANOVA and later a Tukey test, fulfilling the assumptions of Normality and Homogeneity of Variance, indicating the conditions of greater significance for the growth of “conchocelis”. The maximum growth occurred in hydroponic solution A and B with the 25% treatment at 4.15 mm2 as opposed to “Bayfolan®” at 1.54 mm2 . However, with different coverage, 71.56% and 54.93%.
