Problems solved by technology

Among them, sinking net cage culture is easy to catch, and it is currently a commonly used breeding method. However, the mesh number of the cage is too low, and the seedlings are easy to be pinched. It has become the biggest problem, and the yield also rises and falls with the year; while intensive cultivation in cement ponds disrupts the original natural survival characteristics of organisms. Whether the leech seedlings can survive the high temperature is the decisive factor for this model. In the summer when the temperature is above 35°C, the cement will be scalded by the sun, and the effect of changing the water within 24 hours is a drop in the bucket. This method has high investment and low output. Generally, the cost can be recovered after four years of stable production theory, and it is not easy to catch.

Embodiment 1

[0019] The leech breeding method with high survival rate comprises the steps:

[0020] (1) Build a culture pond: build a culture pond and prepare the culture soil. First soak the culture soil with povidone-iodine for 12 hours, then let off the liquid in the soil, spread it on the bottom of the culture pond for 20 cm, and then put it in 25 cm water;

[0021] (2) Breeding leeches: stocking leeches in the breeding pond, without feeding during the hatching period;

[0022] (3) Picking into foam boxes: After 1 month, gently turn the breeding pond, pick out the formed egg cocoons, and pack them into three types of foam boxes separately according to the color of the egg cocoons (pink, white, gray). Each type of seed foam box is pre-placed with 20 cm of sterilized breeding soil. Place egg cocoons neatly on the breeding soil, and then cover the top of the egg cocoons with a pinch of crushed soil. The amount of soil added is just enough to cover the eggs. During the foam box period, c...

Embodiment 2

[0028] The leech breeding method with high survival rate comprises the steps:

[0029] (1) Build a culture pond: build a culture pond and prepare the culture soil. First, soak the culture soil with povidone-iodine for 8 hours, then drain the liquid in the soil, spread it on the bottom of the culture pond for 15 cm, and then put it in 20 cm water;

[0030] (2) Breeding leeches: stocking leeches in the breeding pond, without feeding during the hatching period;

[0031] (3) Picking into foam boxes: After 2 months, gently flip the culture pond, pick out the formed egg cocoons, and pack them into three types of foam boxes separately according to the color of the egg cocoons (pink, white, gray). Each type of seed foam box is pre-placed with 40 cm of sterilized breeding soil. Place egg cocoons neatly on the breeding soil, and then cover the top of the egg cocoons with a pinch of crushed soil. The amount of soil added is just enough to cover the eggs. During the foam box period, che...

Abstract

The invention discloses a method of leech farming of high survival rate. The method comprises the steps of construction of culture ponds, stocking leeches, sorting to foam boxes, transferring of seedling fry boxes, box separation aquaculture, and management of the species separation boxes. Through the management control of incubation at each stage of incubation, seedling box, separation box, and the like, the survival rate of leeches is improved, while the probability of leech infectious diseases is reduced; the capturing is easy, at leech harvest almost all leeches can be fished; even at the summer heat, the growth rate of leeches is little affected; the leech natural survival characteristics is kept, and the economic benefit of leech farming is improved.

Description

technical field [0001] The invention belongs to the technical field of leech cultivation, and in particular relates to a method for cultivating leeches with a high survival rate. Background technique [0002] Leeches, commonly known as leeches, grow and reproduce in inland freshwater waters. They are traditional Chinese special medicinal aquatic animals. Their dried products are processed and used in traditional Chinese medicine. They have the effects of treating stroke, hypertension, dredging, amenorrhea, and traumatic injuries. It is also found that leech preparations have special effects in preventing and treating cardiovascular and cerebrovascular diseases and anticancer. However, over the past few years, the natural environment where leeches grow has been polluted by pesticides, chemical factory sewage, and household garbage, resulting in a serious shortage of leeches, and the contradiction between supply and demand in the market is prominent, and artificial breeding ha...
