Method of multi-layer three-dimensional breeding of babylonia areolata

Abstract

The invention discloses a method of multi-layer three-dimensional breeding of babylonia areolata. A multi-layer breeding cage in the method is composed of a cage top cover, a lower layer cage body, a middle layer cage body, an upper layer cage body, a lower layer bait pipeline, a middle layer bait pipeline and an upper layer bait pipeline. The bait pipelines are fixed to the cage top cover. The outer parts of the bait pipelines are equal in length. During breeding, bait pipe openings are located above the water surface. The inner parts of the bait pipelines are not equal in length, the lower layer bait pipeline is led to the lower layer cage body, the middle layer bait pipeline is led to the middle layer cage body, and the upper layer bait pipeline is led to the upper layer cage body. The method has the advantages that by means of the properly-designed babylonia areolata multi-layer three-dimensional breeding cage, the unit yield consumption is reduced on the basis of not increasing the single-layer breeding density, the output of unit water body is effectively improved, and the breeding yield can be increased by 10-20% compared with traditional factory breeding; no disinfectant is used in the whole breeding process, and produced babylonia areolata commodities are healthy and free of pollution.

Description

technical field [0001] The invention relates to a method for cultivating snails, in particular to a method for multi-layer and three-dimensional cultivation of snails. Background technique [0002] Babylonia areolata (Babylonia areolata), commonly known as flower snail, belongs to Gastropoda, Antyglossacea, Mothiaceae, and Dongfeng snail. It is rich in nutrition and delicious in meat, and is widely loved by people. Because the market potential of Dongfeng snail is great, and it is suitable for industrial farming, it has broad development prospects and has become an important species of marine shellfish farming in the southern coastal areas of China. At present, Dongfeng snail factory culture is mainly based on land-based cement pond running water farming, which has a large amount of water exchange, with a daily flow rate of 300%-500%, and high energy consumption for farming. In order to reduce the energy consumption per unit of production and increase the production of aqua...
