The practical consequences of these changes took the form of increased abundance of fish, waterfowl, freshwater molluscs, rodents, hippopotamus and crocodiles. The riches of this increased aquatic biomass were exploited by humans with rafts, boats, weirs, traps, harpoons, nets, hooks, lines and sinkers. This "riparian" (river) way of life supported much larger communities than could that of typical hunting bands. These changes, along with the local development of pottery (whereby liquids could be both stored and heated) resulted in a "culinary revolution" consisting of soup, fish stew and porridge. The last mentioned implies the cooking of gathered cereals.
