The invention discloses a rapid propagation method for mud fish. The method comprises the following steps of (1) selecting the mud fish which are two to three-winter-old, 15 to 20cm in body length and 30 to 50 grams in
body weight as propagation parents, and ensuring that the female / male ratio of the parent mud fish is 1:2-1:3; (2) taking the parent mud fish out of a culture pond, putting the parent mud fish on a spawning induction
bed, and injecting 800 to 1,000 international units of chorionic
gonadotropin to each parent female mud fish and 400 to 500 international units of chorionic
gonadotropin to each parent male mud fish by adopting an
intramuscular injection method; (3) putting the parent mud fish subjected to spawning induction into an incubation
jar for spawning, taking the parent mud fish in a net of the incubation
jar out after 20 hours of spawning, ensuring that eggs are independently incubated in the incubation
jar, continuously injecting new clear water in the incubation process to ensure that water in the incubation jar flows; (4) after incubating for 1 month, making sure that fries of the mud fish in the length of 2.5-3.6cm are formed. According to the method, the
propagation time of the mud fish is greatly shortened, the
hatching rate is improved, the manpower is reduced, and the
aquaculture economic benefit is improved.
