VIDEO: Stone Fish Traps Explained
[Editor’s Note: Often passed, seldom visited by outsiders, British Columbia’s Central Coast is home to the continent’s longest-settled places and most enduring peoples. In 2012, a special team of Tyee Solutions Society reporters spent some time there. What they found there was a land and culture that has thrived for thousands of years. These are some of those stories. This reporting was produced by Tyee Solutions Society in collaboration with Tides Canada Initiatives (TCI). TCI neither influences nor endorses the particular content of TSS’s reporting.]
Fish traps turn up practically everywhere you find andromous fish—such as salmon and herring—that migrate from the sea to spawn in rivers or close to shore, or where their opposites, catadromous fish like eels swim from lakes and rivers to spawn at sea. The Thames River's medieval fish weirs, the Maori people's eel weirs in New Zealand, the Amazon's ancient 500-square-kilometer weir in Baures, the Passaic River's pre-Colombian weirs in heavily urbanized New Jersey, various European weirs dating to 8,000 years ago: all display a similar ingenuity for gathering similar dinners at little effort.
The Pacific Coast of North America is no different. How the traps were used depended on the fish, the materials available, the broader environment and the human culture. But from California to Alaska, fish traps lined the ocean shores for thousands of years, and their remains are easy to find—provided you know what to look for and understand that the technology was probably highly adaptive to local materials and conditions.
The people of the Northwest Coast domesticated their landscape intensively. In Tla'amin territory, for example, archaeologists have found stone fish traps interspersed with clam gardens. Just as gardeners of domesticated plants cater to their mini-ecosystems, moving around whatever is growing poorly—blueberry bushes, peonies—until they find the spot where the plant thrives, so ancient peoples must have moved and modified their fish traps until they found the sweet spot. The more experience you have with the land or water, the better your garden... or your harvest of seafood.
