Problems solved by technology

The paddy farming model has the following problems: on the one hand, the feed conversion rate is low and the harvesting of leeches is extremely difficult;
Neither the current cage culture nor the cement pond culture can solve the problem of leeches' scattered life, especially the problem of how to adjust the water quality in time during the breeding process

Embodiment 1

[0022] A method for high-density three-dimensional breeding of leeches, including the following steps:

[0023] 1) The installation of aquaculture cages: a culture cage is set in the aquaculture pond with a width of 3 meters and a height of 1 meter. The material of the cage is 20 mesh net cloth, and a layer of bamboo flakes is evenly laid on the bottom of the cage; the upper end of the cage Set an internal fold at 45 degrees from the vertical.

[0024] 2) The setting of the culture substrate: water is injected into the culture pond, the water depth of the culture pond is 0.7 meters, the water temperature is controlled at 25°C, the pH value is 6.5, the water surface outside the cage is set with an ecological floating bed, and gold and silver are set on the ecological floating bed. Grass No. 2, the ecological floating bed area accounts for 2 / 3 of the breeding area; the ecological floating bed is made of bamboo, the length and width of the ecological floating bed are 1.2m and 0.6m res...

Abstract

The invention provides a high-density stereoscopic breeding method for leeches. The method comprises the following steps: (1) setting of a breeding net cage; (2) setting of a breeding medium: injecting water into a breeding pond, setting an ecological floating bed on the water surface outside the net cage, and setting No. 2 Goodyera yamiana on the ecological floating bed, wherein the area of the ecological floating bed occupies 2/3 to 3/4 of breeding area; (3) seedling putting: selecting leech seedlings with the weight of 0.3 to 0.5 gram per piece, and putting the seedlings with the density of0.12 million to 0.16 million pieces per mu; (4) fodder feeding: beginning feeding on the next day after seedling putting, wherein the feeding amount of fodder is 25% to 40% of total mass of leeches,and when the fodder inside the net cage remains 20% to 30%, the next round of fodder feeding is began; and (5) water quality management: spraying a bacteria solution into water at an interval of 15 to20 days, and cleaning impurities in water in time. According to the method, the water quality can be adjusted in time, the breeding density and survival rate of leeches are greatly increased, and theyield is improved.

Description

Technical field [0001] The invention belongs to the technical field of leeches breeding, and specifically relates to a method for high-density three-dimensional breeding of leeches. Background technique [0002] Leech, commonly known as leech, is the general name of the class Annelida in the classification of animals. It grows and reproduces in inland freshwater waters. It is a traditional special medicinal aquatic animal in my country. Its dried products are processed into traditional Chinese medicine and can treat stroke and hypertension. , Clearing blood stasis, amenorrhea, traumatic injury and other effects, especially for the preparation of Chinese patent medicine for the treatment of cardiovascular and cerebrovascular diseases. In recent years, with the continuous in-depth and development of medical research on leeches, the medicinal value has been gradually embodied. Leeches have become one of the most popular Chinese medicinal materials in the world, and they also have bro...
