REPRODUCTION AND DEVELOPMENT OF Porphyra spp. IN NORTHWESTERN ILOCOS, PHILIPPINES. Major Adviser: Prof. Andres Y. Tungpalan, MSc In this archipelago of 7,641 islands, individuals' lifestyle is firmly associated with the ocean. The country's exceptionally useful fisheries, when managed economically, can take care of the developing Philippine populace and accomplish financial development and security. Since the Philippines uphold a quickly expanding populace dependent on marine assets, the reasonable administration of our fisheries ought to be the fundamental exploration plan. It is about time, to search for other seaweed-based business endeavors which could be an alternative and as food to supply the protein needs of the Filipinos. This study gives fundamental and critical data in support of the creation of Porphyra specics evaluation in support of both financial development and environmental prosperity particularly to those Ilocano fisherfolk who have been engaged with the gamet business throughout the years in Northwestem Luzon, particularly in Burgos, and Pagudpud. Porphyra species exhibited a normal bi- phasic life history that alternates with sporophytic conchocelis and gametophytic blades in culture. Porphyra species reproduce through both sexual and asexual methods of reproduction. Among the three (3) Porphyra species in Northwestern Ilocos, P. suborbiculata developed a lot the quickest. Modified Grund Medium, seawater- enriched, and pure seawater are possible for conchocelis culture. The initial two are the most preferred culture media, and capiz shell is the most favored substrate for spores, for they advance the best development and improvement in Porphyra species. ddc THEDIS 16868 16868 0 0 ddc 0 0 MMSU_MAIN MMSU_MAIN THESES 2021-11-19 928 928-Thesis 2021-11-19 2021-11-19 THEDIS ROOM USE ONLY
