Earlier this year, I had the opportunity to accompany Cory and Callie Carawan on a trip to the West Coast. They wanted to survey the shellfish aquaculture industry in Oregon and Washington.<\/p>\n

Whiskey Creek is the largest shellfish hatchery in the United States. It provides oyster, clam and mussel seed for commercial and restoration efforts.<\/p>\n
The hatchery also has been at the forefront of ocean acidification research and adaptation. Beginning in 2007, the hatchery struggled with mass mortalities of their shellfish seed associated with highly corrosive upwelled water off the Oregon coast. In the past few years, thanks to research and improvements in hatchery monitoring techniques, Whiskey Creek has been able to better predict and respond to changes in ocean chemistry and the negative impacts of those changes on shellfish larvae.<\/p>\n

Gordon King, who oversees the company\u2019s mussel farming operations, showed us the Taylor\u2019s massive floating upwelling system, also called a FLUPSY,\u00a0located on Oakland Bay. The FLUPSY provides a favorable growth environment for shellfish seed to grow large enough to be used in growout operations. Paddlewheels cause bay water to flow through mesh-bottomed containers where the shellfish seed are retained. The water carries phytoplankton, food for the seed.<\/p>\n
Gordon also walked us through Taylor\u2019s processing facilities and administrative headquarters, where we gained a better perspective of the scope of the company\u2019s operations.<\/p>\n
Gordon arranged for us to tour one of the company\u2019s local shellfish beds. He even provided us with the necessary gear \u2014 raingear and boots because it was raining, of course, and headlamps because low tide was at about 9 p.m. Jason Ragan, who directs Taylor\u2019s clam and oyster farming operations, brought us to Totten Inlet.<\/p>\n
Although it was rainy and dark, we were able to get an appreciation of the true scope of the production of clams and oysters there on the growing beds at low tide. Jason explained what it takes to plant and grow shellfish. In addition, he gave us some insight on working around large tidal fluctuations and knowing if black bears are near portable toilets.<\/p>\n
