Abstract
The invention discloses a grass carp breeding method comprising the following steps of (1) pond preparation, (2) pond cleaning, (3) fish fingering stocking, (4) fodder feeding, (5) water quality management and (6) disease and insect prevention. One month after the grass carp is placed into the pond, the grass carp is mainly fed by pellet fodder; the protein content of fodder remains 28% to 32%; and then green forage is fed for auxiliary forage. The fodder feed applies to principles of " rough for primary period and fine for final period" and " four fixed time and four checks". Grass carp physique can be enhanced, diseases can be reduced and quick growth of the grass carp can be promoted.
Description
Technical field
The invention belongs to the technical field of the cultivation of fish, mussel, crayfish, lobster, sponge, pearl etc., specifically relate to the raising method of a kind of grass carp.
Background technology
In the breeding process of aquatic products as fish, common way adds artificial feeding bait, thus have ignored the natural bait existed in pool, the phytoplankton existed in pool, zooplankton is the natural bait of fish, the Fast Growth of grass carp can be promoted, but for large-scale fish culture, the zooplankton of spontaneous growth, phytoplankton obviously can not meet the cultivation demand of grass carp, market also have Chinese herbal medicine mixing soya-bean milk carry out raising grass carp, strengthen the physique of grass carp, this grass carp raising method cost for extensive and common grass carp is too high, only to be suitable for family workshop type to breed fish or rareness, valuable fingerling, in addition on market in order to promote the quick growth of grass carp, market there is the fish meal containing hormone, this fish meal relative Chinese herbal medicine mixing soya-bean milk, cost is relatively low, but after this Growth of Grass Carps Ctenopharyngodon Idellus, meat is poor, be of low nutritive value, be unfavorable for that eater's is healthy.
Summary of the invention
In view of this, the object of the present invention is to provide the raising method of a kind of grass carp, the raising method of this grass carp is mixed with soya-bean milk by green manure or muck raises grass carp, the former provides more nutriment of its Fast Growth for zooplankton, phytoplankton and zooplankton are all the natural baits of Growth of Grass Carps Ctenopharyngodon Idellus, a large amount of phytoplanktons and zooplankton have ensured the food source of Growth of Grass Carps Ctenopharyngodon Idellus, especially under grass carp in the pool 5 days, ingestion ability is weak, soya-bean milk can strengthen grass carp physique, reduce grass carp disease, promote that grass carp grows fast.
In order to achieve the above object, the raising method of a kind of grass carp of the present invention, its step is as follows:
1) pond requires: pond area is advisable with 10-20 mu, depth of water 2-2.5 rice, and silt depth is no more than 20 centimetres. every 10 mu of pond match powers are aerator and each 1 of the Autoamtic bait putting machine of 3 kilowatts;
2) preparation of ponds: winter drains Chi Shui, freezes solarization more than 20 days. first 15 days of fingerling stocking, and water inlet 10-20 centimetre, to clean up the pond sterilization with quicklime 150 kilograms for every mu, discharges green manure or the muck that becomes thoroughly decomposed in 5 ~ 8 days before grass carp input;
3) fingerling stocking: around the Spring Festival, put Grass carp 300 tail that specification is 200-250 gram/fish for every mu, specification be 15-20 tail/kilogram crucian kind 300 tail, specification be 5-6 tail/kilogram silver carp kind 50 tail, Variegated 10 tail. with 5% saline solution soaking disinfection 5-10 minute before fingerling stocking, the 1st day ~ 5 days, the pool under grass carp, sprinkle slurry number of times every day and be no less than 2 times, sprinkling slurry amount is 50 ~ 200kg/ every mu, and every mu needs dry soya bean 1 ~ 3kg altogether; The 5th day ~ 15 days, the pool under grass carp, under grass carp, the pool starts to increase throwing bean dregs, soya-bean cake paste or levigate vinasse on the 11st day;
4) feedstuff feeding: under grass carp seedling, the pool is after 1 month, based on pellet of throwing something and feeding, dietary protein level is at 28-32%, auxiliary throwing green forage. feedstuff feeding is followed " front thick rear essence " and the principle of " four fixed four see ", throw something and feed general every day 2 times, to eat up in 2 hours, the Feeding in Grass Carp 8 one-tenth full .3-6 month of being advisable based on protein content of throwing something and feeding be 28% pellet, it is 3% that day throws the rate of raising, green fodder of throwing something and feeding in right amount; The 7-9 month, control pellet feeding volume, it is about 1.5% that day throws the rate of raising, and pellet protein content is 28%, strengthens green fodder feeding volume, controls fish disease and occurs; Protein content of throwing something and feeding the 10-11 month is the pellet of 32%. after pellet a period of time of throwing something and feeding continuously, should stop to feed pellet 1 week, to throw something and feed in interval raw grain feed. note at ordinary times adding the medicines such as vitamin in right amount in feed, avoid grass carp suffer from the diseases such as liver and gall syndrome and cause mortality;
5) water quality management: proper use of aerator, 6-10 month fine day calm weather, oxygenation 2 hours of starting shooting during 1-3 every afternoon, in good time oxygenation in morning; The continuous cloudy day should do sth. in advance oxygenation. new water of in good time annotating to pond, the way of " float little enter, repeatedly change water " is taked progressively to regulate and control the water quality .6-9 month, to annotate every 3-5 days new water 1 time, add water 10 cm at every turn, changes slurry full pool spilling head 1 time every 15-20 days every mu of waters surface 1 meter of depth of water with quicklime 10-20 kilogram;
6) disease control: adopt the mode of " front slightly rear essence, the blue or green combination of essence " to throw something and feed, controlling grass carp liver and gall syndrome to occur. grass carp common disease has red skin disease, fin rot, enteritis disease, generally take the outer bold and vigorous methods for the treatment of combined for oral administration, outer bold and vigorous main based on the disinfectant such as bleaching powder, chlorine dioxide, be used in conjunction 3 days; For oral administration better with " three blooms " pharmaceutical chemistry effect, every 50 kilograms of fish body weight three blooms, admix in feed after 0.3 kilogram and flour paste mix and throw something and feed, be used in conjunction 3-5 days;
Further, in step 2) in, band water is cleaned up the pond, and the depth of water is 45 ~ 60 centimetres, cleans with quicklime 100kg/ mu or bleaching powder 10kg/ mu, disinfects fish pond, after 1 ~ 3 day, fish pond bottom sludge is stirred 1 time and is exposed to the sun.
Further, in step 1) in, discharge green manure 500kg/ every mu or muck 300kg/ every mu in 5 ~ 8 days before grass carp is thrown in, and plant eyebright in fish pond, plant that careless area accounts for pond area 1/3.
Further, in step 3) in, the standard of dry soya bean soybean soaking is good with nick in the middle of two panels cotyledon, soaks get final product defibrination in 4 ~ 6 hours water temperature about 20 DEG C, can wear into slurry 45kg at every turn, wear into starch in latter 1 hour and sprinkle slurry immediately with 1kg soya bean,
Further, in step 6) in, in described three blooms, concrete composition and mass ratio are: rheum officinale 50%, golden cypress 30% and the root of large-flowered skullcap 20%, stir evenly after being ground into flour.
Beneficial effect of the present invention is:
The raising method of grass carp of the present invention is mixed with soya-bean milk by green manure or muck raises grass carp, the former provides more nutriment of its Fast Growth for zooplankton, phytoplankton and zooplankton are all the natural baits of Growth of Grass Carps Ctenopharyngodon Idellus, a large amount of phytoplanktons and zooplankton have ensured the food source of Growth of Grass Carps Ctenopharyngodon Idellus, especially, under grass carp in the pool 5 days, ingestion ability is weak, and soya-bean milk can strengthen grass carp physique, reduce grass carp disease, promote that grass carp grows fast.
