• To catch more fish, the Tla'amin people (native to what is now the Canadian province of British Columbia), set traps in the intertidal zone. The intertidal zone is a coastal area that is underwater during high tide, but exposed to the air during low tide. Tla'amin traps were made of collections of stones or other material. When the tide came in, fish entered the traps with natural tidal currents, swimming over or around the traps' low stone "wall." When the tide receded, these walls prevented the fish from swimming out. Trapped fish were easily harvested from these shallow tidal pools.
