Method for ecological culture of soft-shelled turtles in cattail purifying ponds

Abstract

The invention provides a method for ecological culture of soft-shelled turtles in cattail purifying ponds. The method comprises the following steps: S1: selecting shallow ponds or river bends or low-lying irrigated fields as soft-shelled turtle culture ponds; S2: planting cattail in centers of big soft-shelled turtle ponds and small soft-shelled turtle ponds; S3: delivering caridina into the ponds; S4: seed selection and stocking: selecting soft-shelled turtles, which are robust in physical constitution, high in activity, complete in appearance and normal in physical appearance, are 2 to 3 years old and have the body weight of 1.5kg to 2kg, placing the selected soft-shelled turtles in the big soft-shelled turtle ponds by the rate of 150 to 220 soft-shelled turtles per mu; and selecting youngling soft-shelled turtles, which are robust in physical constitution, high in activity and complete in appearance, placing the selected youngling soft-shelled turtles in the small soft-shelled turtle ponds by the rate of 350 to 600 soft-shelled turtles per mu; S5: feedstuff feeding; and S6: water quality management. By cattail planted ponds, the soft-shelled turtles are tip in tail and free of atail biting phenomenon, and produced soft-shelled turtles are relatively good in physical appearance; the cattail planted ponds are basically free of diseases; and in addition, the cattail can further exert a heat-preserving action, and the soft-shelled turtles eco-cultured in the cattail purifying ponds have the characteristics of ecology, environment-friendliness, low wounded and sick rate, water saving and the like.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a method for ecologically cultivating soft-shelled turtles in cattail grass purification ponds. Background technique [0002] Soft-shelled turtle (Amyda Sincnsis), is the common name of soft-shelled turtle, also called turtle, water fish, oviparous amphibian reptile, and is the general designation of soft-shelled aquatic turtle of turtle family Turtle family. There are more than 20 kinds. There are mainly Chinese soft-shelled soft-shelled turtles, Shanrui soft-shelled turtles, spotted soft-shelled turtles, and soft-shelled turtles, among which Chinese soft-shelled soft-shelled turtles are the most common. The soft-shelled turtle is not only a delicacy on the dining table, but also a high-quality material for the first-class banquet, and it can also be used as a traditional Chinese medicine material. It has many nourishing and medicinal effects, such as clearing heat and nou...

Problems solved by technology

[0003] The output of pure wild soft-shelled turtles is extremely low, and the phenomenon of biting each other is serious, resulting in a low survival rate, which is not conducive to large-scale predation. However, the existing large-scale aquaculture mostly adopts greenhouse constant temperature farming, and feeds are fed all year round, which is much shorter than the production cycle. Rapid breeding within a short period of time, the nutrition is not high, the meat is not delicious, and hormones will remain in the aquatic organisms, seriously endangering the health of the eaters
