Abstract
The invention discloses a leech high-density stereoscopic cultivation method. The leech high-density stereoscopic cultivation method includes the following steps: arranging cultivation net cages, arranging cultivation media, putting in seedlings, putting in feeds, managing water quality and carrying out inter-cultivation outside the net cages. According to the leech high-density stereoscopic cultivation method, the cultivation density and the survival rate of leeches are greatly improved, and the yield is improved. By means of the existing leech cultivating technology, the dried leech products per mu is about 40kg, after the leech high-density stereoscopic cultivation method is adopted, the dried leech products per mu can reach about 50kg, and the yield is improved by 25%. The feeds (apple snails and field snails) and the leeches are inter-cultivated, the use rate of soil source is improved, meanwhile, lemna minor or water hyacinth planted on the water surface can meet the growth requirements of the apple snails and the field snails, two purposes are achieved, the use rate of the feeds is improved, the production cost is saved, and the economic benefits are improved.
Description
Technical field
The invention belongs to the hirudiniculture technical field, be specifically related to a kind of method of high density three-dimensional culture leech.
Background technology
Leech, the popular name leech, it is the general designation of Annelida Hirudinea on animal classification, growth and breeding in the freshwater of inland, it is the medicinal aquatic animal of the traditional special type of China, its dried product is concocted the rear traditional Chinese medical science and is used as medicine, there is the treatment apoplexy, hypertension, the clear stasis of blood, amenorrhoea, the effects such as traumatic injury, Chinese patent drug especially for preparation treatment cardiovascular and cerebrovascular disease, in recent years, along with medical science deepening continuously and developing leech research, medical value obtains embodiment gradually, leech one of the well sold and in short supply traditional Chinese medicine that become international, in modern medicine and pharmacology, also have broad application prospects.But the living environment of leech is subject to severe contamination in recent years, people are predatory the seizure again, causes wild resource day by day exhausted, and imbalance between supply and demand is very outstanding, and the leech market demand increases gradually both at home and abroad, and the artificial feeding leech is imperative.The leech strong adaptability, anti-hungry ability is strong, has extremely strong premunition, and the artificial feeding leech is not subject to regional condition restriction, but support in pond, support in hole, cylinder is supported, bucket is supported etc., and it has characteristics such as not accounting for labour, feed cost are low, small investment, instant effect.
At present, hirudiniculture mainly contains three kinds of modes: the cultivation of (1) rice field extensive style; (2) cage culture; (3) cement pit cultivation.There is following problem in the paddy field aquaculture pattern: on the one hand, feed conversion rate hangs down and leech is gathered extremely difficult; On the other hand, can't grasp the birth and old age, sickness and death situation of leech.Current cage culture and cement pit cultivation all can't solve the dispersion problem concerning life of leech.
Summary of the invention
The purpose of this invention is to provide a kind of method of high density three-dimensional culture leech, greatly increased hirudiniculture density and survival rate, improved output.
Technical scheme of the present invention: a kind of leech high density three-dimensional culture method comprises the following steps:
The setting of a, fish culture net cage: fish culture net cage is set in culturing pool, and net cage is wide 2～4 meters, high 1.2～1.8 meters, and net cage material selection 40～60 purpose screen cloths are laid one deck bamboo basketry sheet at the net cage bottom even;
The setting of b, cultivation matrix: water filling in culturing pool, water surface planting duckweed or weter hyacinth that net cage is inside and outside, cultivated area accounts for 2/3～3/4 of cultured area;
C, seedling throw in: the leech seedling that to choose body weight be 0.3～0.5 gram/bar, by the density of 200～500/square metre, put in a suitable place to breed;
D, feedstuff feeding: seedling is thrown in and starts feeding rear next day, and the feedstuff feeding amount is 25～35% of leech gross weight, when the feed in net cage remains 20～30%, carries out the feedstuff feeding of next round;
E, water quality management: sprayed bacterium liquid every 5～7 days in water, and clear up in time the foreign material in water;
F, net cage overcoat are supported: support Pomacea canaliculata and/or river snail at the fish culture net cage overcoat, the duckweed of water surface planting or weter hyacinth can be for Pomacea canaliculata and/or river snail growths.
Further, in described step a, the net cage upper end arranges and the rectangular interior Origuchi of vertical plane, 0.15～0.2 meter of Origuchi length.
Further, in described step b, the culturing pool depth of water is 0.7～1 meter.
Further, in described step b, water temperature is controlled at 20～28 ℃, pH value 6.5～7.5.
Further, in described step e, bacterium liquid is selected EM bacterium liquid.
The EM bacterium liquid that the present invention selects adopts the probio stoste by 5 kind of 10 genus such as photosynthetic bacteria, lactobacillus, yeast flora, actinomycete group, thread flora more than 80 kind the composition of the microorganisms of Japanese EM company and China's cooperative development.
Beneficial effect of the present invention:
(1) cultural method of the present invention has increased hirudiniculture density and survival rate greatly, has improved output, existing hirudiniculture technology, per mu yield leech dry product is in the 40kg left and right, adopt cultural method of the present invention, the per mu yield of leech dry product can reach the 50kg left and right, and output has approximately improved 25%.
(2) this method is supported feed (Pomacea canaliculata and river snail) and leech cover, has improved the availability of land resources, and the duckweed of water surface planting or weter hyacinth again can be required for Pomacea canaliculata and river snail growth simultaneously, kill two birds with one stone.
(3) this method high-density breeding also is conducive to improve the availability of feed, has saved production cost, has improved economic benefit.
