 The project aimed at making salt water and desert combinations productive through application of the simplest, low cost rational scientific approaches had its first prototype in the Salton Sea in southern California.A simple food chain consisting of sewage and other waste on which salt- and heat-resistant algae would feed that then fed brine shrimp that then could be utilized in aquaculture as a food source for larger fishes was developed.The idea was then expanded to larger scale manmade salt water tidal ponds in coastal deserts that could be utilized for aquaculture in controlled ponds and a tide-controlled food source for larger scale "fish ranching" that would come to the tidal wash on the coast to feed.
