Document Description
This project would add 20 additional clam rafts to the 10 rafts already in place existing in an existing area of mariculture operation in Humboldt Bay, increasing the footprint of the operation in that area by about .62 acres in this area. This is a small component of the larger Coast Seafoods mariculture operation, which was addressed in a prior MND (SCH#1999032069). The clam rafts are floating structures approximately 10 ft by 20 ft, anchored to the bay substrate in approximately 20 feet of water, on one side of the Mad River Slough channel. The rafts are used to grow clams for 1-6 months from seed to approximately 3600 um, at which point they are shipped elsewhere for grow-out, harvest, and sale.
