Abstract

The present invention discloses an ecological reproduction method for soft-shelled turtles, belonging to the field of aquaculture. The method comprises the following steps of: breed selection, feed selection, egg collection and incubation management. The breed selection refers to selecting wild soft-shelled turtles each of which weighs equal to or greater than 1.5 kg and has no diseases or injuries, wherein the ratio of female to male is 3-4:1, and the stocking density is 200 turtles/mu to 300 turtles/mu. The feed selection refers to selecting feed mainly comprising fresh fish, shrimps, spiral-shelled mollusks, mussels and animal innards, and supplemented by plant food organisms, with the daily ration being 7%-8% of the total weight of the soft-shelled turtles. The egg collection refers to laying 1 cm to 3 cm thick sand on the bottom of egg collecting boxes before egg collection. During the spawning season, fertilized eggs are dig out of sandpiles of spawning grounds, and the fertilized eggs are placed in the egg collecting boxes with care and arranged neatly. After the egg collection, the fertilized eggs are covered by find sand. The technique means can increase the medicinal value of the soft-shelled turtles, increase the hatching rate of the multiplication of the soft-shelled turtles, yield strong larvae and improve economic benefits for producers.

Description

Soft-shelled turtle ecological breeding method
Technical field
