Artificial propagation method of native fish in Chenghai Lake

The invention provides an artificial propagation method of native fish in the Chenghai Lake, which is characterized by comprising the following steps of: (1) parent fish selection: selecting native fish deriving from the Chenghai Lake; (2) parent fish training: training the parent fish in a natural ecological environment simulating the Chenghai Lake; (3) propagation: building a side slope of 35-45 DEG by using stone blocks on one side of a pool, paving sands on the side slope, and progagating through methods of natural egg laying, spawning hastening by using medicine and artificial fertilization in sequence; (4) hatching: putting fish eggs in a hatching pool for hatching; (5) fry culturing: starting feeding the fish fries 3-4 days after hatching, and culturing the fish fries in a fry pool after breeding the fries 2 weeks; and (6) adult fish cultivation: cultivating the fish fries after the fish fried grow to 3-5 cm. The native fish in the Chenghai Lake can be subjected to scale production by using the artific
