The March 18, 1962 Chicago Tribune ran this Closer Than We Think strip about hydrofungal farming. The text of the strip appears below.
An Ohio State University professor is researching a novel way to keep the world's supply of food proteins in step with the explosive growth of the population.
Dr. William D. Gray believes an answer might be found by cultivating certain fast-growing fungi rich in proteins. These fungi must be grown in large quantities of water, either salt of fresh, aerated by bubble streams.
One way would be to mature the "crop" in the ocean. Plant flasks would be fastened to slowly rocking underwater tables supplied with air from hoses to the surface. These mechanized "hydrofungal" centers might prove just as effective for protein cultivation as the sea itself is for the fish to eat.
