Inside a cavernous steel warehouse built in the 1910s for the Port of Los Angeles’ then-booming fishing industry, Catalina Sea Ranch’s unique aquaculture labs are blazing a trail for a budding new U.S. industry. A Cryolab nurtures bunches of genetically diverse breeding mussels growing in baths infused with phytoplankton. Many of their shiny black-shelled progenies, hanging on lines in federal waters 10 miles offshore, are awaiting the ranch’s first harvest in December.And ranch founder Phil Cruver just began work to produce his newest crop: giant sea kelp.The U.S. Department of Energy recently awarded Catalina Sea Ranch $450,000 to help kick off the new offshore aquaculture industry, farming kelp for human and animal consumption. The ranch is the first U.S. aquaculture farm permitted in federal waters.
