Summary of the invention
Training is for overcoming drawbacks described above, and the present invention devises yellow panel loach seedlings intensive cultivation method.
Yellow panel loach seedlings intensive cultivation method, is characterized in that: yellow panel loach seedlings is cultivated and comprised the following steps, A: cultivate pond
The construction on the pool and setting, B: pond put in a suitable place to breed before process, putting in a suitable place to breed of C: yellow panel loach seedlings, D: the management of fry rearing early stage, E:
Yellow plate loach crow son's sub-sieve divides the pool, F: the management of fry late stage of culture, G: daily management measure.
Cultivate the construction in pond and setting: yellow panel loach seedlings cultivates that pond should select having abundant water resources, draining is convenient, can pipe energy
Row, water holding capacity is strong, water quality is pure and fresh, without the local construction of any pollution;Yellow panel loach seedlings needs segmentation to cultivate, and cultivates pond with some
Mouth pond is one group, pond area 50 400 square metres, and at one, yellow panel loach seedlings cultivation base needs some groups and cultivates ponds,
Chi Shen is 1 meter, and bottom is tamped, pond four wall hardening bank protection, lays 20 centimetres of the earth rich in humus at the bottom of pond;Pond surrounding
Arranging escaping-preventing facilities, use the polyethylene mesh sheet of 60 centimetres wide, lower end buries 10 centimetres underground, and aerial parts supports with wood chip or bamboo chip
Rise;Water inlet is arranged with discharge outlet diagonal angle, and water inlet PVC pipeline introduces the top in pond, exceeds the water surface 20 centimetres, draining
Mouth is located in pond at minimum point, leads to outside pond by pipeline, enters discharge outlet and all use 100 mesh sieve tulles to filter.
Pond put in a suitable place to breed before process: yellow panel loach seedlings is put in a suitable place to breed first 10 days, carries out the preparation of ponds, reinforces Chi Geng, repaiies
Copy escaping-preventing facilities, at the bottom of leveling pond after discharge water 10 centimetres, use fresh lump lime by the consumption of 0.2 kilogram every square metre, raw
Slurrying full pond float after Calx efflorescence, carries out disinfection to pond bottom pool wall;Cleaning up the pond after sterilizing three days, pond adds water to 30 lis
Rice, uses the cattle manure fully become thoroughly decomposed, applies by the consumption of 0.5 0.6 kilograms every square metre, and decomposed cow dung need to add water and stir into excrement
Slurry, and add lime disinfection in right amount, then uniformly splash in full pond, carries out water quality and fosters and apply fertilizer.
Putting in a suitable place to breed of yellow panel loach seedlings: yellow plate loach breeds the time in May, and the fry after hatching is put into 50 square metres and cultivates ponds
Cultivating, breeding density is every square metre of 1000 tails;Draw in the net sub-sieve when fry rearing is to 3 centimetres, put in a suitable place to breed by specification different respectively
The Nei Fen pool, pond is cultivated, and along with the growth of fry, needing repeatedly to draw in the net sub-sieve puts in a suitable place to breed, and fry close for specification is put in a suitable place to breed same
In pond, specifically put mode in a suitable place to breed: 3 centimetres of fingerling every square metre 200 tails;5 centimetres of fingerling stocking density are every square metre of 150 tails;
8 centimetres of fingerling stocking density are every square metre and put 100 tails in a suitable place to breed;Within being every square metre of 80 tails more than 8 centimetres of fingerling stocking density;
During fry draws in the net to turn pool sub-sieve, it should be noted that the water temperature temperature difference does not exceeds 2 DEG C, the fry through transporting for long-distance will be at slow Seedling
Reason: fish fry bag is put in pond waters after 10 minutes, makes water temperature inside and outside bag close, then opens bag mouth and adds appropriate pond
Water, makes fry progressively adapt to throw in again;Must continue to try water before fry is put in a suitable place to breed, it was demonstrated that after pool water is nontoxic, just can put Seedling.
The management of fry rearing early stage: enter, from yellow plate loach spray, the crow son that the pool grows up to 3 centimetres to fry, for yellow plate loach fry
Early stage cultivate;The emphases of supervision in this stage is that foster and apply fertilizer water quality, bean milk of throwing something and feeding, suitably note changes water, promotes fry fast-growth;
Zooplankton is the important bait of loach fry, by the way of water quality of fostering and apply fertilizer, promotes the zooplankton amount reproduction in pond;
Fertilization type, with the organic cow and bullock manure fully become thoroughly decomposed, biological fish-fertilizer, inorganic fertilizer, uses a small amount of fertilization principle repeatedly, root
Apply fertilizers scientifically according to water quality condition, when water transparency is more than 20 centimetres, fertilising material should be mended in time;Dose, organic excrement every time
Fertile every square metre is less than 0.3 kilogram, biological fish-fertilizer every square metre 50 grams, carbamide, calcium superphosphate one class inorganic fertilizer every square metre
Respectively executing 25 grams, fertilising in every 3 days is once every time;Bean milk is splashed and is sooner or later respectively splashed once every day;At bean milk of splashing after 10 days
While, it is properly added mixed bait;Carry out water body exchange by water injection pipeline, within 3 days, change water once, change water 5 ~ 10 every time
Centimetre, keep water quality pure and fresh well.
Yellow plate loach crow son's sub-sieve divides the pool: when yellow plate loach crow son's length is to 3 centimetres of specifications, and size differentiation is obvious, the crow of big specification
It is strong that son robs food ability, fast growth, the growth of compacting small dimension fry, finally make small dimension fry because ingesting undernutrition and
Exhaustion, makes the overall cultivating survival rate of yellow panel loach seedlings decline, so to draw in the net sub-sieve in time, carries out point pool and cultivates;Draw in the net
Fine day is carried out, and selects fry not raise the nose above water to breathe and the calm morning, to stop eating the previous day drawn in the net, if desired for long distance transportation palpus
Taking exercise once, point pool is just not required to take exercise nearby, at first 7 days of point pool, first disinfects pond to be put in a suitable place to breed, nontoxic to water
And other conditions suitable time, draw in the net, crow is young through screen cloth sub-sieve, singly puts cultivation, less than 3 centimetres rule more than 3 centimetres of specifications
Lattice singly put cultivation;Carry out drawing in the net, sub-sieve, transport, operation of being careful when putting in a suitable place to breed, reduce yellow plate loach crow son's chance of injury.
The management of fry late stage of culture: after yellow plate loach crow son divides the pool, pond water level progressively adds and is deep to 50 centimetres, and water quality is trained
Educating similar to early stage breeding phase, water transparency controls at 25 centimetres, and within every 3 ~ 5 days, note changes water once, each 10 ~ 15 centimetres;
Bait, based on mixed bait, uses fixed point feeding technology, arranges bait table in pond, uses steel bar framework sewing fish fry to arrange net
The method of sheet makes bait table, and each bait table is 1 square metre, arranges one every 10 meters in pond, and bait table is away from pool side 2
Rice, uses long handle to scoop and throws something and feeds, bait is directly put in bait table;Bait be fish flour, soybean cake, peanut cake, rapeseed cake, wheat bran,
The mixture of wheat-middlings, mineral salt and vitamin, raw material agglomerating is thrown something and fed through fully pulverizing, stirring again;Every morning, noon, under
Noon respectively throws something and feeds once, day feeding volume be deposit pool Huang plate loach body weight 4% ~ 10%, concrete feeding volume according to water quality at that time, weather,
Situation of ingesting is grasped flexibly;During water temperature more than 15 DEG C, the food ration of yellow plate loach increases with the rising of water temperature, in water temperature 25 ~ 28
DEG C optimum water temperature in the range of, ingesting of yellow plate loach is the most vigorous, and water temperature is then faded more than 28 DEG C of appetite, when water temperature is higher than
30 DEG C or during less than 15 DEG C, yellow plate loach food ration is less, should reduce throwing something and feeding of bait, it is to avoid the waste of bait.
