A method for mainly raising snails in low-yielding paddy fields

Abstract

The invention relates to the field of aquaculture, and discloses a method for transforming low-yield paddy fields to mainly raise snails. It includes the following steps: (1) Paddy field selection, select low-yield paddy fields outside the basic farmland protection area, and the conditions meet the requirements of SC / T 1009. (2) Paddy field transformation, transforming the paddy field into a breeding field with an area of ​​1‑3 mu, a flat bottom without ditches, a ridge height of 50 cm, a water storage depth of 30 cm, and a breeding field with inlet and outlet outlets. (3) The species of snails should be released before mid-April. The weight of the individual should be ≥3g, and the ratio of male and female species should be 2‑6:1. Put 300kg of snail species per 667㎡. (4) Feed selection and feeding. By feeding different forms of feed at different times, the survival rate of snails can be increased in the early stage, and the excessive growth of the number of snails can be suppressed in the later stage to maintain a relatively stable number of snails. Balanced feeding of high-quality feed and Do a good job in daily water quality management, inspection and other work to ensure the normal growth of breeding objects. (5) Obtain a large quantity of high-quality large-scale snails to supply the market through appropriate fishing methods.

Description

technical field [0001] The invention relates to the technical field of aquaculture, and in particular relates to a method for cultivating the ring-helix snail in low-yield paddy fields. Background technique [0002] Ring-lobed snails (commonly known as stone snails) are one of the main large and medium-sized indigenous freshwater snail groups in my country. The meat is delicious and delicious, and it is a typical high-protein, low-fat high-quality aquatic product. For a long time, most of the snails on the market come from natural fishing in the waters of shallow lakes in the middle and lower reaches of the Yangtze River, such as Hunan, Hubei, Jiangxi, etc. With the improvement of people's living standards, the market demand is increasing, and the natural fishing output is far In order to meet the market's demand for ring-lobed snails, large-scale cultivation of ring-lobed snails is imperative. At present, there are many researches and productions on field snail culture, a...
