Red Seaweed Porphyra spp. (Bangiales) from Urimessing Waters of Ambon Island - Maluku

Abstract A study on the cultivation of Porphyra spp. has been carried out in waters Ambon Island. This plant is great favor with local communities but not able to meet broader demands. The purpose this research was look into future mass culture. In splashing zone, which about 10 m above sea level, samples gametophyte foliose or thalli were taken. thallus brought laboratory and maintained a 100-liter container. During rearing period, released spermatia fertilized carpogonia. Carpogonia develop carposporangia release zygotospores outside thallus. small zygotospore develops large carpospore. Carpospores are forerunners new sporophytes if they find correct substrate. laboratory, nacre layer pearl oyster shells used replace natural substrates. attached germinated grew conchocelis. conchocelis then conchosporangia outward, followed by conchospores. Conchospores source grown polyethylene nylon nets. that nets moved their environments so could keep growing.
