Kuptana describes the ancient practices of catching hundreds of fish using stone weirs in the summer.
The Northern Copper Inuit - A History
William Kuptana. During the summer, the Copper Inuit would pile up stone corrals in the shallow streams to trap the fish. When the fish swam through to the corrals, the Inuit would block the entrance to prevent the fish from escaping. The take from the corral would total a few hundred fish. The various ways they'd prepare the fish is by drying and then smoking to preserve it over the winter months. The remainder of the catch was then buried with stone caches that were built so other predators could not help themselves to the fish.
