California’s rugged North Coast lays claim to one of the state’s most valuable commercial fisheries: Dungeness crab. Millions of pounds of this meaty delicacy are pulled in each year from Morro Bay to the California-Oregon border, making for an industry valued at $32 million to $95 million per year. But there’s another catch: Many of the thousands of crab pots set in the sea don’t make their way back. Now, a group of fishermen collaborating with UC Davis are working to remove the lost crabbing gear from the ocean and sell it back to the original owners under what they hope will be an economically sustainable model for future cleanups.
Lowering a white disk off a boat and into Lake Tahoe’s blue waters was once the most widely used indicator of the lake’s clarity and health. Today, the Secchi disk is still an important tool, but 46 years after UC Davis first began continuous monitoring of Lake Tahoe, an array of new technologies and computer models are helping scientists better understand what has proven to be a complex ecosystem.
