Abstract

The invention discloses a cultivating method of loach larvae. The cultivating method comprises the following steps: (1) preparing a loach pond: applying a fermentation organic fertilizer or biological fertilizer to an inner pond; (2) cultivating algae bloom loach larvae: feeding egg yolk, wheel animalcule and ground water earthworm, and controlling the oxygen aeration of pond water; and (3) cultivating sepia loach larvae: transferring the sepia loach larvae cultivated in the inner pond to gullies of an orchard to cultivate, feeding a powdery loach feed with the protein content of 40%-50% and water earthworms, and feeding an expanded particle feed with the particle size of 1.0mm when the loach larvae grow to be inched loach larvae. According to the cultivating method, the bottom material and the water quality of the pond are improved, the biological structure of natural forages is improved, the forages are scientifically fed, toxic and harmful substances such as ammonia nitrogen, nitrite and the like in the pond are controlled, dissolved oxygen of pond water is increased, and the natural forages of planktons are increased, so that the inched loach larvae have strong physiques and are high in survival rate, diseases of the loach larvae are reduced, and the rapid growth of the loach larvae is promoted.

Description

The breeding method of mud fish fry
Technical field
The invention belongs to the technical field of the cultivation of loach class, mussel, crayfish, lobster, sponge, pearl etc., specifically relate to a kind of breeding method of mud fish fry.
Background technology
Chinese snake head is the one of Misgurnus auguillicaudatus, is distributed in the river, shoal of China middle and lower reach of Yangtze River and the island of Taiwan northwestward more, and this kind has that growth is fast, the culture-cycle is short, and individual large, resistance against diseases is strong, and profit margin is large.And fine and tender taste, delicious flavour, nutritious, be rich in multivitamin and the trace element such as high protein, low fat, low cholesterol and VA, VB, VB2, calcium, iron, iodine; In addition containing a kind of unsaturated fatty acid of similar twenty carbon penetenoic acid, there is human body vascular ageing, be thus of value to the elderly and cardiovascular patient.But the cultivating survival rate before Chinese snake head cun sheet is very low, and the survival rate of current domestic most loach seedling raiser is below 30%, and this is the difficult problem that annoying the fast development of loach breeding industry all the time, particularly a large bottleneck of the breeding of mature loach is greatly developed in restriction.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of breeding method of mud fish fry, the breeding method of this mud fish fry, by improving pond substrate, water quality, improves natural bait biological structure, science feeding bait, control the poisonous and harmful substances such as pond ammonia nitrogen, nitrite, improve pond water dissolved oxygen, increase the effect of plankton natural bait, make loach cun seedling physique strong, survival rate is high, reduce mud fish fry disease, promote that mud fish fry grows fast.
In order to achieve the above object, a kind of breeding method of mud fish fry, its step is as follows:
1) the loach pool prepares: the interior pool area cultivating spray loach seedling is: 30 ~ 50m 2, the dark 0.6 ~ 0.8mm in pond 2.
The internal pool adopts at the bottom of pond, the potassium permanganate internal pool and pool wall carries out sterilization of cleaning up the pond, and applies fermentation fertilizer or bio-fertilizer in the interior pool, and the filling of the interior pool is carried out needing Detoxified treatment and plankton to cultivate through the new water filtered;
2) spray loach seedling is cultivated: raised scattered by spray loach seedling and cultivate and the pool in Detoxified treatment through water quality, in the internal pool, coolant-temperature gage carries out temperature control, make the temperature difference can not more than 3 ~ 5 DEG C, spray loach seedling to enter behind the interior pool between-7 days, to throw something and feed the water earthworm of yolk, wheel animalcule and pulverizing, the oxygenation of control Chi Shui, spray loach seedling, through the cultivation of about 1 week time, grows into black sub-loach seedling;
3) black sub-loach seedling is cultivated: from about the 8th day, the crow loach seedling cultivated on the interior pool is transferred in orchard and is cultivated in gully, crude protein content of throwing something and feeding is loach mash feed and the water silk earthworm of 40 ~ 50%, when reaching very little seed to loach fry, particle diameter of throwing something and feeding is the expanded pellet feed of 1.0mm;
Further, loach fry disease prevention and cure are also comprised:
(1) infusorian disease: make regular check on the multiple parasitosis of black sub-loach seedling to cun sheet loach seedling stage, especially protozoon class disease, mainly contain the infusorian diseases such as cup worm, oblique tube insect, Trichodina, adopt copper sulphate and mixture of ferrous sulfate or adopt prosperous copper and the clean full pool spilling head of protozoon, can effectively kill this kind of parasite.
(2) bubble illness: black sub-loach seedling grows to 1 ~ 1.5cm, as too large in interior pool Midst density, when dissolved oxygen is too high, loach water flower seedling the most easily suffers from bubble illness, employing is thrown something and fed water silk earthworm, NaCl and enzyme and electrolysis multidimensional, add subsurface-water injection or other pond bottom water simultaneously, this disease can be made effectively to be prevented and treated.
(3) hemorrhage, enteritis disease: black sub-loach seedling is to a cun sheet loach seedling stage, loach fry common disease also has bacillary hemorrhage, enteritis disease, in powder, add allicin and three blooms or three sealworts throw something and feed, and accomplish when daily throwing something and feeding on a small quantity repeatedly, effectively to prevent this two kinds of diseases.
(4) when temperature instability, can in mash feed, add the fragrant positive air water of appropriate lotus, the husky star of the thioether of external application simultaneously, in case fungal infection.
Further, in step 1) in, discharge green manure 500kg/ every mu or muck 300kg/ every mu in 5 ~ 8 days before mud fish fry is thrown in, and plant agropyron in the loach pool, plant that careless area accounts for pond area 1/3.
Further, in step 3) in, the 1st day ~ 5 days, the pool under black sub-mud fish fry, sprinkle slurry number of times every day and be no less than 2 times, sprinkling slurry amount is 50 ~ 80kg/ every mu, and every mu needs dry soya bean 0.5 ~ 1kg altogether; The 5th day ~ 15 days, the pool under mud fish fry, sprinkle slurry number of times every day and be no less than 2 times, sprinkling slurry amount is 70 ~ 100kg/ every mu, and every mu needs dry soya bean 1 ~ 2kg altogether; Under mud fish fry, the pool starts to increase throwing bean dregs, soya-bean cake paste or levigate vinasse on the 11st day.
Further, in step 3) in, in gully, introduce running water, protection network is set at two ends, gully.
Beneficial effect of the present invention is:
1, the breeding method of mud fish fry of the present invention is by improving pond substrate, water quality, improve natural bait biological structure, science feeding bait, control the poisonous and harmful substances such as pond ammonia nitrogen, nitrite, improve pond water dissolved oxygen, increase the effect of plankton natural bait, make loach cun seedling physique strong, survival rate is high, reduce mud fish fry disease, promote that mud fish fry grows fast.
2, the breeding method of mud fish fry of the present invention can solve during loach fry is cultivated the multiple crucial technical problem affecting survival rate, and the cultivating survival rate of Chinese snake head seed can be made to improve and be stabilized in more than 90%.
