Black carp are native to the major Pacific Ocean drainages of eastern Asia from China to far eastern Russia and possibly Vietnam. Water quality physicochemical indexes (ammonia nitrogen, nitrite, dissolved oxygen, pH, transparency, and water temperature) and fish growth (body length, body weight, and survival rate) were determined regularly.Disinfection, sterilization, and water quality regulation were performed regularly to prevent diseases. In bays, the principal species are yellow perch, brown bullhead, pumpkinseed, emerald shiner, walleye, and sauger.
