The use of fish as fertilizers dates back to at least the era of the Pyramids in Egypt where farmers and homesteaders utilized the carcass and liquids from fish harvested from the Nile to provide important fertility to their crops.

More recently North American Indians in the 16th century were observed placing whole fish into the soil beneath crops of corn and squash.

“A friendly Indian named Squanto helped the colonists. He showed them how to plant corn and how to live on the edge of the wilderness… As cultivating maize was unfamiliar to the Pilgrims, they relied on advice from Squanto, who shared with them the secret of proper maize-planting technique – sticking the seed in the little heaps of dirt, accompanied by beans and squash that would later twine themselves up the tall stalks. And he told the Pilgrims to fertilize the soil by burying fish alongside the maize seed, a traditional native technique for producing bountiful harvest. Following this advice, the colonists grew so much maize that it became the centerpiece of the first Thanksgiving.”

The early agriculturists of this planet understood the importance of keeping their crops fertile for rapid healthy growth. They learned that all types of fish provided excellent results when used as fertilizers for their crops.
