How banned fish traps could help salmon in the PNW

Nearly a century ago, fish traps were banned on the Columbia River. The practice had been used by indigenous communities of the Northwest for a millenia, but when European settlers expanded west, they set up their own industrial versions, catching as much as 73 tons of salmon a season. Voters would ban these traps in Washington and Oregon in 1934 and 1948, respectively. But now some permitted experiments are being conducted using traps to sustainably harvest fish.
