Description

A kind of cultural method improving stingray body color
Technical field
The present invention relates to freshwater fish culturing technical fields, and in particular to a kind of cultural method for improving stingray body color.
Background technique
As human living standard is continuously improved, country is gradually done to high-quality fish demand, is manually supported in high density It grows under environment, bait is single, growing environment limitation, life style transformation, stress reaction etc., causes the gorgeous body colour of fish and is difficult to It is inherited, meat nutrition gradually declines；It is changed into cinerous by gorgeous yellow in the breeding process of Pelteobagrus fulvidraco, reduction The economic well-being of workers and staff of raiser.
Fish body surface color can change with the variation of growing environment, be divided into physiology transformation and Morphological Transitions, physiology transformation The origin cause of formation is mainly that the pigment granule in skin corium in chromatoplast spreads or gathers, and is showed by hormone and nerve modulation effect； Morphological Transitions are mainly the migration of epidermis chromatophore and pigment granule variable density；Physiology changes based on nerve modulation, leads to It crosses tubulin to transport pigment granule directionality, can be completed in the short time；Morphological Transitions are adjusted with itself internal excretory system Based on, it is a passive process affected by environment.Currently, the phenomenon that in order to improve stingray body color alienation, culturist adopts more It is controlled with feed nutrition, such as CN201610589741.7, CN201510405009.5, CN201510506769.5 public A kind of mixed feed of regulation stingray body color is opened, but the report studied in terms of cultural technique is existing, therefore, this hair Bright people probes by the way that on yellow catfish growing, regular, environment influences, ingesting influences various aspects, has studied a kind of improvement Pelteobagrus fulvidraco The cultural method of body colour provides new approaches for raiser.
Summary of the invention
The present invention is in order to solve the above technical problems, the present invention provides a kind of cultural methods for improving stingray body color.
Specifically realized according to following technical scheme:
The present invention provides a kind of cultural methods for improving stingray body color, include the following steps:
S1 pond treatment: it is carried out disinfection with quick lime slurry to pond, after drying, according to 46-50mL/m2Amount by chitosan Spraying suspension and four wall of pond and bottom of pond, after drying, water filling；Before juvenile fish is put in a suitable place to breed, oxygenation is carried out to oxygen-containing using aerator Amount >=8mg/L, and well-rotted farmyard manure is put into according to 25-35kg/ mus of amount, juvenile fish is put in a suitable place to breed after placing 3 days；
S2 juvenile fish raises the stage: feeding 2 basal feeds daily, each feeding volume is the 2-3% of weight；Basal feed with Parts by weight meter is made of the following raw material: 20-40 parts of fishbone dust, 5-10 parts of corn, and 15-20 parts of wheat bran, 4-8 parts of walnut, sesame 5- 10 parts, 15-20 parts of jujube, 1-2 parts of peanut oil, 0.5-1 parts of mineral powder, 2-3 parts of tangerine orange concentrate, 0.2-0.5 parts of mango yogurt； Per two weeks feeds the modified bead of lutein according to the amount of weight 4-6%, and is powered and vibrates 10min；
The S3 adult fish rearing stage: feeding 3 basal feeds daily, and each feeding volume is the 2-3% of weight；Basal feed with Parts by weight meter is made of the following raw material: 20-40 parts of fishbone dust, 5-10 parts of corn, and 15-20 parts of wheat bran, 4-8 parts of walnut, sesame 5- 10 parts, 15-20 parts of jujube, 1-2 parts of peanut oil, 0.5-1.5 parts of red thorn rattan, 0.5-1 parts of mineral powder, 2-3 parts of tangerine orange concentrate, awns 0.2-0.5 parts of fruit yoghourt；Per two weeks feeds the modified bead of lutein according to the amount of weight 4-6%, and is powered and vibrates 10min.
Chitosan mass concentration is 5-8% in the chitosan suspension.
The well-rotted farmyard manure is by following parts by weight material mixing, compost fermentation: 20-30 parts of pig manure, chicken manure 10-20 Part, 15-25 parts of cow dung, 0.1-0.3 parts of wheel animalcule, 0.2-0.6 parts of earthworm.
Pig manure in the well-rotted farmyard manure, chicken manure, cow dung are to add the smelly chrysanthemum of day flow vector 6-8% in daily ration to be fed Food is after 20 days, the excrement of poultry generation.
The juvenile fish raises the stage, controls oxygen content >=6mg/L using aerator, controls 10-35 DEG C of water temperature.
The adult fish rearing stage controls oxygen content >=12mg/L using aerator.
The mineral powder includes: 4-8 parts of ardealite, 8-9 parts of basalt, 3-4 parts of anorthite, potassium feldspar 1- in parts by weight 2 parts, 2-3 parts of chlorite.
The mineral powder is added after ardealite, basalt, anorthite, potassium feldspar, chlorite grinding, mixing aforementioned The dilute NaOH solution of material mass (0.5-0.8) times stirs 15min, is warming up under the conditions of material temperature is 180-200 DEG C and handles Not less than 20min, then it is warming up to processing under the conditions of material temperature is 400-450 DEG C and is not less than 10min.
The mass concentration of the dilute NaOH solution is 15-20%.
The tangerine orange concentrate contains in every gram: tartaric acid 32-45mg, citric acid 23-30mg, citral 12-17mg, dimension Raw element B13-19mg, calcium 5-8mg, iron 2-3mg, surplus is vitamin C.
The modified bead of the lutein includes: 2-5 parts of lutein, 0.1-0.3 parts of chitosan, guar gum in parts by weight 1-2 parts, 0.2-0.6 parts of sodium tripolyphosphate, 20-25 parts of water.
The beneficial effects of the present invention are:
Cultural method of the invention, which has, maintains Pelteobagrus fulvidraco nature body colour, enhances Pelteobagrus fulvidraco immunity and stress ability, mentions High juvenile fish survival rate, nutrient utilization and the effect for promoting to absorb growth；Using cultural method of the invention, the death rate is reduced 53%, disease incidence reduces 85%, and feed efficiency mentions 20%.
The present invention carries out the feeding of pig, ox, chicken using smelly chrysanthemum, and collects excrement, decomposed with wheel animalcule, earthworm progress, changes It has been apt to microorganisms in water situation and nutrient situation, so that probiotics increases, and as juvenile fish nutritional supplementation, so that juvenile growth There is natural pigment ingredient in environment, prevent epidermis pigment lightening.
The present invention adds tangerine orange concentrate and mango yogurt in basal feed, not only provides Pelteobagrus fulvidraco nutritional ingredient, also The disease resistance and stress ability of Pelteobagrus fulvidraco are improved, the reparation for improving tyrosine enzyme activity to promote melanin to lack.
The present invention is by activating mineral powder, so that mineral powder contains various active mineral element, nutrition is promoted to inhale It receives, transports lutein directionality, and then maintain stingray body color；The present invention utilizes lutein, chitosan, cluster bean Glue, sodium tripolyphosphate not only make lutein be easy to absorb, and also control the rate of release of lutein, at energization oscillation Reason further enhances the disease-resistant of Pelteobagrus fulvidraco, antipollution and resisting stress so that the modified bead of lutein is easy to be absorbed by Pelteobagrus fulvidraco Property, ensure that make on the basis of the body colour and meat health rate of Pelteobagrus fulvidraco it is Fresh & Tender in Texture.
