Gyotaku is the Japanese art of fish painting. You catch a fish, dry it off, paint it with ink, then press rice paper or linen onto the fish. What you get is an accurate print of the exact fish you caught. The Japanese used them centuries ago as a record of fish caught in tournaments. Traditionally only red or black ink was used, but some modern Gyotaku artists will paint the colors of the fish so that your print is accurate in color as well as size.
