Creating the tools for primitive fishing requires understanding a world very unlike our own. A world where one or two degrees of temperature difference make habitat livable or not. A world where you feel sound with your skin and smell through water. The underwater world of the fish, their habits, food, and habitats can teach us much about how to feed ourselves.
The oceans, lakes, rivers, and streams offer abundance of food in times past and even still. Fishing with ancient tackle, learning to understand the waters and its denizens, and learning how to protect that resource come together in the ancient skill of fishing.
