[0004] Existing Chinese patent document (publication number: CN104855309B) discloses a kind of cultivation method of artificial pond snails, within 30 days before the snails go on the market; Wherein: the first 10 days start line monitoring pond water dissolved oxygen, when pond water dissolved oxygen is lower than 5.0 mg / L, start the aeration machine to keep the dissolved oxygen in the pool above the critical value; feed calcium-increasing feed every morning, so that the intake of finished snails in the square meter is more than 4 grams, and feed the spiral snails every night. Algae liquid, so that the algae intake of finished snails in the square meter is more than 5 mg; at this stage, the water temperature is between 20 and 25°C day and night. Feeds are mainly calcium powder, fish meal, etc., the effect of increasing production is not obvious, and at the same time, it has a single effect, and the taste and production of snails are not good.

Embodiment 1

[0023] A kind of high-efficiency cultivation method of snails of the present embodiment comprises the following steps:

[0024] Step 1. The aquaculture pond is rectangular, with an area of ​​6 mu, and the surrounding slopes are inclined to the center to form a slope. The depth of the center of the pond is 0.8m, and silt is laid along the slope. The thickness of the silt is 12cm. Tube oxygenation facilities;

[0025] Step 2, inject water to the pond to make the pond water capacity be 60% of the pond volume, then add nutrient solution to the pond, drain water after 4 days, until the water capacity of the pond is 20% of the pond volume, then inject clear water until the water capacity is 65% of the pond volume %, then put 120 snails per square meter into the pond;

[0026] Step 3: Discharge water at a rate of 4cm / min every other day until the water capacity of the pond is 30% of the pond volume, then inject water at a rate of 8cm / min until the water capacity of the pond is 60% o...

Embodiment 2

[0036] A kind of high-efficiency cultivation method of snails of the present embodiment comprises the following steps:

[0037] Step 1. The aquaculture pond is rectangular, with an area of ​​10 mu, and the surroundings are inclined to the center to form a slope. The depth of the center of the pond is 1.2m. Along the slope, silt is laid. The thickness of the silt is 16cm. Tube oxygenation facilities;

[0038] Step 2, inject water to the pond so that the pond water capacity is 60% of the pond volume, then add nutrient solution to the pond, drain water after 6 days, until the water capacity of the pond is 20% of the pond volume, then inject clear water until the water capacity is 65% of the pond volume %, then put 140 snails per square meter into the pond;

[0039] Step 3: Discharge water at a rate of 6cm / min every 3 days until the water capacity of the pond is 30% of the pond volume, then inject water at a rate of 8cm / min until the water capacity of the pond is 60% of the pond ...

Embodiment 3

[0049] A kind of high-efficiency cultivation method of snails of the present embodiment comprises the following steps:

[0050] Step 1, the breeding pond is rectangular, with an area of ​​8 acres, and the surroundings are inclined to the center to form a slope. The depth of the center of the pond is 1m, and silt is laid along the slope. The thickness of the silt is 14cm. Oxygenation facilities;

[0051] Step 2, inject water to the pond to make the pond water capacity be 60% of the pond volume, then add nutrient solution to the pond, drain water after 5 days, until the water capacity of the pond is 20% of the pond volume, and then inject clear water until the water capacity is 65% of the pond volume %, and then put 130 snails per square meter into the pond;

[0052] Step 3: Discharge water at a rate of 4-6cm / min every 2 days until the water capacity of the pond is 30% of the pond volume, and then inject water at a rate of 8cm / min until the water capacity of the pond is 60% of ...

Abstract

The invention discloses a high-efficiency breeding method of snails. The high-efficiency breeding method comprises the following steps that step I, a breeding pond is rectangular and is 6-10 mu in area, the periphery of the breeding pond is inclined to the center to form a slope, the depth in the center of the pond is 0.8-1.2 m, sludge is paved along the slope, the thickness of the sludge is 12-16cm, and a water injecting opening, a water draining opening and a micropore pipe oxygen increasing facility are formed / arranged in the pond. According to the high-efficiency breeding method of snailsdisclosed by the invention, firstly water is injected, then nutrient fluid is applied, and then water is drained, so that the pond water is rich in nutritive substances and sterilization effects areachieved; and then the content of oxygen in the water is maintained through running water every 2-4 days. The yield of the snails is increased, and Chinese herbal medicine fermentation fluid containsrich nutrient substances of protein, carbohydrate, vitamins, amino acids and the like, and is high in metabolism in snail bodies.

Description

technical field [0001] The invention relates to the technical field of shellfish cultivation, in particular to a high-efficiency cultivation method for snails. Background technique [0002] The snail is the common name of the square ring snail. It is the whole of the square ring snail or other animals of the same genus. The shell is conical, hard and thick, and the shell is about 3 cm high. The body spiral layer is slightly larger; the shell surface is yellowish brown or dark brown, with obvious growth lines and thick spiral ribs, the shell mouth is oval, the edge is complete, and the horny, yellowish brown, oval, smooth, with concentric With circular growth patterns, snails often inhabit lakes, ponds, paddy fields and slow-flowing rivers and streams that are warm in winter and cool in summer, with soft subsoil and rich bait. When the temperature is below ℃ and above 30℃, the feeding activity will be stopped. The artificial breeding of snails can be raised in special ponds,...
