It’s Dungeness crab season: Will this year be a big catch?
BIOLOGY - Marine biologist Alan Shanks has a simple trap that allows him to predict the amount of Dungeness crab will be available for fisherfolk. For the past 25 years, Shanks has compared the yields of the winter commercial catch to the baby crabs his water-jug trap collects each summer. He’s found that the number of baby crabs that arrive on the coast can be used to estimate the size of the state’s commercial harvest of adult Dungeness crab years in the future, with a 12 percent margin of error.
