Description
Technical field
The present invention relates to a kind of methods of survival rate after raising Culter fish culture parent propagation, belong to Culter fish culture technology neck
Domain.
Background technique
Culter fish is full of nutrition with its, Fresh & Tender in Texture and liked by numerous consumers, and price is much higher than four large Chinese carps.Closely
Nian Lai, as wild Spanish mackerels stock number falls sharply, and the marketable fish market demand is big, and the artificial breeding of Culter fish has been risen in many places,
And because Culter piscinity is stronger, and Culter fish parent generally is handled using modes such as artificial induced spawning, artificial insemination in artificial breeding.This
Kind manual intervention is very big to the damage of Culter fish, drastically influences the postnatal survival rate of Culter fish, and in the prior art, Culter fish postpartum is dead
Rate is up to 95% or more.
Summary of the invention
In view of the deficiency of the prior art, the object of the present invention is to provide a kind of raising Culter fish culture parent propagations
The method of survival rate afterwards.
To achieve the above object, the technical solution adopted by the present invention is that: improve survival rate after Culter fish culture parent propagation
Method includes the following steps:
(1) parent's stimulation by running water: stimulation by running water pond, normal aquaculture pond are built, two tank depths are in 2-2.5m, stimulation by running water pond
Cultivation density be 100 tails/mu, wherein stimulation by running water pond includes pond body, and pool bottom is built into wavy and wavy bottom
Portion's entire surface in upwards it is skewed, the high-end side in wavy bottom is corresponded in pond body and is fixed with water pushing plate, water pushing plate is located at
In pond body and position that water pushing plate is in contact with pond body is fixed with linear bearing, bearing block, drive shaft is welded on water pushing plate, drive
Moving axis is connected with linear motor；In the pond body other side, mesh plate is driven in setting, and the length for driving mesh plate can be with stimulation by running water pond

There is sliding block, center is provided with hole, corresponds at the top of pond body and has also been bolted support shaft, support shaft at sliding axle both ends
Setting orthogonal with sliding axle, sliding block horizontally slip in support shaft；Push rod is further fixed on sliding axle；On normal aquaculture pond
It is also placed in the one side wall opposite with stimulation by running water pond and drives mesh plate, drive the width of mesh plate and the width of normal aquaculture pond
Degree is adapted, which is directly placed in normal aquaculture pond；In stimulation by running water pond and normal cultivation
The buffer channel for being connected to the two is built between pond, on stimulation by running water pond and on buffer channel junction, normal aquaculture pond
The flapper of drawing and pulling type is respectively provided with buffer channel junction, flapper periphery card sets sealing ring；It is then shut off active catch
Plate, the wild Spanish mackerels parent that capture is come are put into stimulation by running water pond, drive water pushing plate by linear motor, push water flow,
Realize stimulation by running water, controlling flowing water speed in stimulation by running water pond is 0.5-3m/s, and every 5-7 days stimulation by running water are primary, primary to stimulate
30min or more；By opening or closing flapper, alternating of the Culter fish in stimulation by running water pond and in normal aquaculture pond is realized
Cultivation；
(2) parent drives stimulation: it is primary using stimulation is driven during every adjacent stimulation by running water of parent twice, once stimulate 25-
40min that is, in stimulation by running water pond or places waterproof robot, drives Culter fish parent by waterproof robot, or pass through
The realization of mesh plate 4 is driven to drive；
(3) Chinese herbal medicine stimulates: during parent's stimulation by running water and parent drive stimulation progress, feeding addition tool paralysis to Culter fish and makees
The feed of herbal composite, wherein herbal composite is integrally fed by being added in feed after milling, in
The additive amount of herbal-composition is the 5-8% of feed gross weight, and feed number and time carries out according to conventional cultivation；
(4) 1 age of first familiar generation stimulates: pressing the combination stimulus method continued stimulus Culter fish of abovementioned steps (1), step (2) and step (3)
After parent 3-5 months, selects temper to compare docile Culter fish parent and hybridize, obtain first familiar generation, F1 generation is first put into normally
In aquaculture pond after conventional cultivation to 1 age, supported during 5-10 month using driving mesh plate F1 generation 1 age fish is rushed to stimulation by running water
It grows in pond, the Chinese herbal medicine of stimulation and step (3) is driven to parent's stimulation by running water of F1 generation repetition step (1), the parent of step (2)
It stimulates, monthly 2-3 times, after continued stimulus 3-5 months, rushes to conventional cultivation in normal aquaculture pond；
(5) 2 age of first familiar generation stimulates: F1 generation selects temper relatively quiet, during month current year 5-10, catches up with since 2 ages
Into stimulation by running water aquaculture pond, 2 age of F1 generation fish is stimulated by the stimulus method of abovementioned steps (1), step (2) and step (3), monthly 1-
After 2 times continued stimulus 3-5 months, conventional cultivation in normal aquaculture pond is rushed to；
(6) 3 age of first familiar generation is to the stimulation during maturation: F1 generation since 3 ages in mature this period, from 3 age of F1 generation
Middle selection temper is relatively quiet, during the 5-10 month of current year, by the thorn of abovementioned steps (1), step (2) and step (3)
The method of swashing stimulation F1 generation fish, monthly 1 time；
(7) hybridization F2 generation stimulation: from by step (6) handle mature F1 generation in pick out temper comparatively quietly it is female,
Male each 5-8 item of Culter fish is hybridized, and F2 generation is obtained, and F2 generation is first put into normal aquaculture pond after conventional cultivation to 1 age, to F2 generation weight
Multiple stimulation of the F1 generation in step (4), step (5) and step (6)；
(8) breeding is completed: temper comparatively quietly female, male Culter is picked out from the mature F2 generation handled by step (7)
Each 5-8 item of fish is hybridized, and F3 generation is obtained, and the F3 generation selected as cultivation parent, is sent into normal aquaculture pond and cultivated,
Survival rate is up to 75% or more after it is bred.
Further, the herbal composite of above-mentioned tool paralysis effect is prepared by the raw material of following weight percent: white
Head father-in-law 30-50%, Radix Astragali 20-30%, Schisandra chinensis 10-15%, fructus lycii 15-25%.
The beneficial effects of the present invention are: using method of the invention, it is possible to selecting the more quiet mild Culter fish of temper
Parent, postnatal survival rate substantially increase (up to 75% or more), and relatively stable, have to modern times artificial breeding fine
Impetus.
