“There's only a handful of guys that are really big diggers,” says Shane Baker, a veteran Tulalip fisherman and boat owner. He's been diving both commercially and recreationally for 17 years. With strong currents and visibility often limited to a few feet, Baker says intuition often is what makes a top-notch diver. “Some guys pick it up fast and some guys just don't,” Baker said. Mental strength also is important. “In my head I prepare a couple days in advance and get psyched up,” Baker said. This is exactly the mentality towards commercial diving that the Tulalips want to encourage, McHugh said. “We like to keep it competitive,” he said. The policies forcing fishermen to work quickly help prevent problems, he said, such as divers only harvesting the highest quality specimens and tossing the rest. That practice could harm geoduck populations over time. The high-speed derby method comes at a cost.
