Low-yield paddy field bellamya mono-culture method

Abstract

The invention relates to the field of aquaculture, and discloses a transformed low-yield paddy field bellamya mono-culture method which includes the steps: (1) paddy field selection, to be specific, selecting a low-yield paddy field meeting the specification of SC / T 1009 except for a basic farmland preservation area; (2) paddy field transformation, to be specific, transforming the paddy field intoan aquaculture field with the area of 1-3mu, the ridge height of 50cm and the water storage depth of 30cm and with a flat and non-grooved bottom, a water inlet and a water outlet; (3) bellamya seed throwing, to be specific, throwing 300kg of bellamya seeds into every 667m<2> of the aquaculture field before the middle ten days of April; (4) feed selection and feeding, to be specific, feeding feedin different forms in different periods to increase the survival rate of young bellamyas in an early period and inhibit excessive growth of the number of the young bellamyas and maintain stable numberof the bellamyas in a later period, feeding high-quality feed in a balanced manner and performing operations such as daily water quality management and inspection to ensure normal growth of aquaculture objects; (5) acquiring plentiful high-quality large-sized bellamya supply markets by a proper catching method. The weight of an individual bellamya is larger than or equal to 3g, and the proportionof male and female bellamya seeds is (2-6):1.

Description

Technical field [0001] The invention relates to the technical field of aquaculture, and in particular to a method for mainly cultivating ring snails in low-yield rice fields. Background technique [0002] Ring snails (commonly known as stone snails) are one of the main large and medium-sized indigenous freshwater snail groups in my country. They have the advantages of wide distribution, strong adaptability to the environment, fast growth, and strong reproduction. The meat is delicious and delicious. It is a typical aquatic product with high protein and low fat. For a long time, the snails on the market have mostly come from natural fishing in the shallow lakes of the middle and lower reaches of the Yangtze River, such as Hunan, Hubei, and Jiangxi. With the improvement of people’s living standards, the market demand is increasing, and the natural fishing output is far It cannot meet the market's demand for ring snails, and large-scale cultivation of ring snails is imperative.
