Abstract

The invention relates to a breeding method of pelteobagrus fulvidraco. The breeding method comprises the following steps: when fries of the pelteobagrus fulvidraco grow to 3-4 cm, putting the fries into a pond, before putting the fries into the pond, treating the fries with urea water of which the mass percentage is 0.2% for 2 minutes, and then treating the fries with a baking soda solution of 1% for 2 minutes; and 2-5 months after the fries are put into the pond, using a feed A for raising the fries, 5 months after the fries are put into the pond, using a feed B for raising the fries, and a month before the pelteobagrus fulvidraco is taken out of the pond, using a feed C for raising the pelteobagrus fulvidraco. According to the breeding method of the pelteobagrus fulvidraco, provided by the invention, the fries of the pelteobagrus fulvidraco are treated before being put into the pond, so that the environmental adaptability of the pelteobagrus fulvidraco is promoted, and the situation that the fries are dead after being put into the pond is avoided; different feeds are used for the pelteobagrus fulvidraco during different growth periods of the pelteobagrus fulvidraco, so that the growth rate and the nutrient value of the pelteobagrus fulvidraco are improved.

Description

The cultural method of a kind of Pelteobagrus fulvidraco

Technical field

The invention belongs to cultivation field, be specifically related to the cultural method of a kind of Pelteobagrus fulvidraco.

Background technology

Pelteobagrus fulvidraco body is long, and abdomen is put down, and body rear portion is slightly flat-sided.Head is large and flat flat, and kiss circle is blunt, and mouth is large, and the next, upper lower jaw equal tool fine hair shape serration, eye is little.Palpus 4 is right, and several upper jaws must be long especially mostly.Without squama.The hard thorn of dorsal fin and the prosperity of pectoral fin equal tool, hard thorn point band is toxic, can sounding during thorn activity.Pectoral fin is short and small.Body bluish yellow look, the mostly irregular brown speckle of several tools; Each fin ash black-tape is yellow.This fish belongs to temperate water fishes.Survival temperature 0 ~ 38 DEG C.Optimum growth temp 25 ~ 28 DEG C, pH value range 6.0 ~ 9.0, optimum pH is 7.0 ~ 8.4.Hypoxia-resistant capacity is general.Dissolved oxygen in water grows normally when more than 3mg/L, raise the nose above water to breathe lower than occurring during 2mg/L, lower than meeting death by suffocation during 1mg/L.Therefore the adaptive capacity to environment of Pelteobagrus fulvidraco is poor.

Summary of the invention

The object of this invention is to provide the cultural method of a kind of Pelteobagrus fulvidraco, by using different feeds to Pelteobagrus fulvidraco process and at different times, promoting the speed of growth of Pelteobagrus fulvidraco, reduce disease and occur.

The present invention is achieved through the following technical solutions:

A cultural method for Pelteobagrus fulvidraco, comprises the following steps:

Grow to the 3-4cm pool at present at advanced fry of yellow catfish, Xia Tangqian, by the urea water process 2min of fry service property (quality) mark 0.4%, then use the saleratus solution process 2min of 1%;

Under fry when pool 2-5 month, use feed A to feed, feed A is prepared by following raw material by weight: soya-bean cake 32 parts, 12 parts, wheat bran, 15 parts, bean worm powder, Os Sus domestica powder 7 parts, Pan rush down 0.6 part, leaf, stiff silkworm 0.11 part, granatum 2.2 parts, teasel root 0.25 part, paniculate swallowwort 0.62 part, potherb mustard 0.12 part, B B-complex 0.02 part;

Under nursery, the pool is after 5 months, and use feed B to feed, feed B is prepared by following raw material by weight: soya-bean cake 18 parts, 8 parts, wheat bran, 2 parts, sodium bicarbonate, rape cake 18 parts, pearl white 36 parts, wormwood 1 part, Hedge Prinsepia Nut 0.2 part, aleppo avens 0.25 part;

The pool previous moon is gone out Pelteobagrus fulvidraco, use feed C to feed, feed C is prepared by following raw material by weight: 5 parts, yolk, peanut powder 12 parts, selenium yeast 0.5 part, soybean protein 35 parts, calcium powder 4.5 parts, betel nut 1.8 parts, the fruit of Rangoon creeper 0.2 part, rice bud 2.2 parts, Phoenix Tree Seed 0.1 part.

Preferably, feed B uses following methods preparation, a, is broken into Powdered by 36 parts, fish scale, adds 0.5 part, sodium bicarbonate and mix, add water 8-10 part, and firmly rubbing, makes sodium bicarbonate be dissolved completely in pearl white surface;

B, by wormwood 1 part of fragmentation, then to mix with the above-mentioned pearl white handled well, 25 DEG C of lower seal fermentation process 10 days;

C, soya-bean cake 18 parts, 8 parts, wheat bran, rape cake 18 parts, Hedge Prinsepia Nut 0.2 part, aleppo avens 0.25 part is respectively broken, the soya-bean cake after fragmentation, wheat bran, rape cake are mixed with 0.5 part, sodium bicarbonate, sealing and fermenting 2 days;

D, step b, step c are obtained raw material mix, being adjusted to water content is 20%, 25 DEG C of lower seal fermentation process 10 days, then mixes with Hedge Prinsepia Nut, aleppo avens, 1 part, sodium bicarbonate, granulation.

Further, the bean worm powder in feed A is in siccative.

Beneficial effect of the present invention: the cultural method of Pelteobagrus fulvidraco provided by the invention is by processing at lower pool money advanced fry of yellow catfish, improve the adaptive capacity of Pelteobagrus fulvidraco to environment, prevent under fry dead behind the pool, by using different feeds in different growing stages, specific aim can be had more, calcareous and protein content is promoted early stage in growth, promote the speed of growth of Pelteobagrus fulvidraco, and by adding the Chinese medicinal ingredients of compound in feed, both can be combined with other compositions, improve the utilization rate of feed, disease resistance and the speed of growth of Pelteobagrus fulvidraco can be promoted again, before going out the pool, use feed C can promote the speed of growth of feed, the Se content of Pelteobagrus fulvidraco can be promoted again, the health value of further lifting Pelteobagrus fulvidraco.Use method of the present invention to cultivate Pelteobagrus fulvidraco simultaneously and can improve the adaptive capacity of Pelteobagrus fulvidraco to environment, make Pelteobagrus fulvidraco still keep normal growth when comparatively large and dissolved oxygen amount is at 1.5-2mg/L in difference variation, reduce the death rate caused due to environmental change in yellow catfish growing process and raise.

Detailed description of the invention

A cultural method for Pelteobagrus fulvidraco, comprises the following steps:

D, step b, step c are obtained raw material mix, being adjusted to water content is 20%, 25 DEG C of lower seal fermentation process 10 days, then mixes with Hedge Prinsepia Nut, aleppo avens, 1 part, sodium bicarbonate, granulation.

Use the survival rate under the advanced fry of yellow catfish after the urea water process of 0.4% behind the pool high, when urea water concentration is greater than 0.5%, then greatly can reduces the survival rate behind the pool under Pelteobagrus fulvidraco, when urea water concentration is less than 0.2%, Pelteobagrus fulvidraco not affected substantially.

Breeding feed of the present invention is used to cultivate Pelteobagrus fulvidraco, control group is set, control group 1 uses conventional method to cultivate, control group 2 does not use feed A, and control group 3 does not use feed B, and control group 4 does not use urea water process, feed consumption is identical, other are consistent, and 1 year test period, result of the test is as following table:

Table 1

As shown in Table 1, use method of the present invention not only can improve the speed of growth of Pelteobagrus fulvidraco, and the death rate reduced in growth period and case fatality rate, the utilization rate of feed can also be improved.

The nutrition of the Pelteobagrus fulvidraco that the Pelteobagrus fulvidraco using feed of the present invention to cultivate and commonsense method cultivate contrasts as following table:

	Protein (g/100g)	Vitamin E (mg/100g)	Zinc (mg/100g)	Iron (mg/100g)	Se content (μ g/100g)
						The inventive method	18.52	1.62	1.56	8.3	22.31
Conventional method	17.78	1.49	1.48	6.4	16.05

Table 2

As shown in Table 2, the protein content of Pelteobagrus fulvidraco of the inventive method cultivation is higher, especially Se content relatively and conventional method have obvious lifting, improve the health value of Pelteobagrus fulvidraco.
