The Market Fish and Shellfish Encyclopedia, created online by fisheries writer and researcher Masataka Fujiwara, known as Bozu Konnyaku, is a comprehensive reference to edible aquatic life and other organisms. It features more than 2,500 species, covering fish, mollusks, crustaceans, other animals, seaweeds and plants. Entries bring together practical identification information and details on flavor, recommended cooking methods, processed products, history and regional names.

The site helps readers explore species through both general and scientific classifications, indexes and search guidance, with explanations of how to prepare and enjoy them. Its articles and columns also share food experiences, market observations, regional food traditions and research into the origins of fish names. Alongside the online encyclopedia, Fujiwara has authored books on premium fish, lesser-known seafood, sushi, fish preparation and regional cuisine, including illustrated and compact editions.

Designed for curious diners as well as fish enthusiasts, anglers and seafood professionals, the resource connects biological knowledge with the everyday pleasures of buying, cooking and eating seafood
