The intent of this book is to offer a primer to any individual, family, village cooperative, NGO, state, federal funding agency, or corporation that wishes to introduce Porphyra (known as Nori in Japan) farming as a socio-economic development driving force. This effort is not intended to be a textbook on Porphyra biology but a reference tool for nori cultivation from the conchocelis culture system through blade harvest and primary processing. Our hope is to provide aquaculture extension agents a teaching guide for nori cultivation. This guide will provide step-by-step instruction for the assembly of a nori production system, care, maintenance, harvesting, and product preservation.
