The Table Rock Fish Hatchery is operated by the NC Wildlife Resources Commission and is located near Morganton, NC on Irish Creek in the Catawba River Basin. Water is gravity fed from the main reservoir for the hatchery on the creek through four indoor troughs that hold freshwater mussels. Water from a 1-acre production pond is also mixed with the reservoir water in the trough to increase temperature and food availability. Because mussels not indigenous to the Catawba River Basin are cultured there, an elaborate scheme was put in place to prevent potential escapement of mussels.
Initially, mussels are held in 8-inch square, stainless steel cages of 0.5 or 1-mm mesh. Water is delivered into the cages which contain a layer of substrate in which the mussels will bury. As the mussels outgrow the cages, they are released into the trough where mesh dividers keep individual batches of mussels separate.
