Abstract
The invention discloses a kind of snakehead ecology mating systems, comprising the following steps: step (1) selects water source, and water source has intake；Step (2), designs hatching apparatus, and the hatching apparatus includes incubator, sunshade net and hatching streams；Step (3) breeds snakehead.The shortcomings that method provided by the present invention can overcome traditional snakehead hatching emergence rate to be influenced by water quality, temperature change, improves spawning rate, the rate of fertilization, emergence rate of snakehead.
Description
Technical field
The present invention relates to the snakehead mating system of culture fishery more particularly to a kind of snakehead ecology mating systems.
Background technique
The problem of country's snakehead incubating oosperm is mainly based on Lentic hatching in facility at present, this technology is main
It shows:
(1) water body is smaller in facility, and due to needing built-in water plant and parent population activity reason, in night easily anoxic, water quality becomes
It is bad.
(2) breeding facility water body is small, and water temperature is influenced by temperature, especially the 5-6 month temperature variation of snakehead mating period
Greatly, day and night temperature is big, and breeding is caused to fail.
(3) parent population lacks water flow stimulation, and oviposition, rate of fertilization are low.
Summary of the invention
Goal of the invention: in order to overcome above-mentioned the deficiencies in the prior art, the present invention provides a kind of snakehead ecology breeding
Method promotes snakehead oviposition, fertilization and development of fertilized ova, improves emergence rate under the premise of keeping water quality water temperature.
Technical solution: snakehead ecology mating system of the present invention selects water source, water source has the following steps are included: step (1)
Intake；Step (2), designs hatching apparatus, and hatching apparatus includes incubator, sunshade net and hatching streams；Step (3), breeding
Snakehead.
Intake is located at 3 meters of the water source water surface hereinafter, intake water temperature is greater than 25 DEG C.
The coverage of water at water source is greater than 10 mu, and the depth of water is greater than 4 meters.
Incubator be it is netted, be suspended in streams, 0~2/3 part is in water.
Hatch the sluicing control valve that streams downstream is equipped with control water velocity.
The flow velocity for hatching streams is 0.2~0.3 meter per second.
Winter Ling Shuo≤2 of snakehead.
Working principle: the present invention simulates snakehead in nature using the big water body such as pond, reservoir, river as water source
Under, it is frequently located in water cleaning, water temperature stability, has fine bourn, have the characteristics of soft water plant place spawning and hatching, engineer goes out class
Snakehead breeding is carried out like environment.
The utility model has the advantages that method provided by the present invention can overcome traditional snakehead hatching emergence rate by water quality, temperature change
The shortcomings that influence, improves spawning rate, the rate of fertilization, emergence rate of snakehead.
Detailed description of the invention
Fig. 1 is that snakehead ecology breeds facility figure；
Fig. 2 is that snakehead ecology breeds programme diagram.
Specific embodiment
The present invention is implemented in Jurong City, scenic spot, Maoshan Mountain tomb East Village tomb east reservoir Jurong south China aquaculture cooperative society,
Ecology breeding facility is established, 3 meters of the reservoir water surface is taken to be lauched as water source, deep water is introduced into ground irrigation canals and ditches, in irrigation canals and ditches
If suspension type incubator, hatchery facility surrounding sets up sunshade net, and snakehead parent population by sex ration 1:1 is put into incubator after routinely hastening parturition
In, water plant hatching is put into case, daily cleaning incubator 3 times, sluicing control valve controls water level 10-20cm suitable for reading from incubator.
It hastens parturition altogether 8 groups, obtains 13.3 ten thousand tail of seedling.
Snakehead parent population hastens parturition, hatches, the specific method is as follows for nursery for present invention progress:
Step (1) selects water source, and need to select coverage of water is 10 mu or more, 4 meters of the depth of water or more of reservoir 1；It is required that water quality
Limpid, water body health is pollution-free.
Step (2), design incubator 4, intake 1-1 and hatching streams 3, comprising the following steps:
Step (2.1) designs incubator 4, as shown in Figure 1, incubator is that 80-100 mesh nylon is made into 600mm*600mm*
1000mm net cage shape, it is suitable for reading to be connected with zipper, it is suspended in streams, 2/3 leaching foam is in water.
Step (2.2), design intake 1-1 and hatching streams 3, are arranged intake 1-1 away from 3 meters of the reservoir water surface or less；Small stream
Stream upstream sets control valve for water pump 1-3, controls inflow and water intake velocity；3 wide 1.5 meters of the hatching streams of design, it is 1 meter deep；Hatching
Fixed steelframe is set on streams, for fixing incubator 4 and sunshade net 2；Streams downstream sets sluicing control valve 4-1, for controlling
Water velocity.
(3) it breeds, as shown in Fig. 2, the snakehead parent population to reach maturity in 2 age in winter of snakehead Juvenile stage, raun requires abdominal circumference
>=12 centimetres, body is >=22 centimetres, 0.6-0.8 kilograms of weight long；Milter requires abdominal circumference >=12 centimetre, and body is >=26 centimetres long, weight
0.8-1 kilograms；It is disease-free and injury-free, it is matched by 1:1 male and female, conventional ocyodinic is illustratively hastened parturition or parent population of not hastening parturition is directly placed into hatching
Case places into appropriate Leersia Sw+tender withy leaf, is made into artificial fish nest, and artificial fish nest is bubbled through the water column.When intake water temperature stability exists
At 25 DEG C or more, streams control valve for water pump is opened, flow cavitation result is in 0.2-0.3 meter per second, and through 24 hours or so, parent population can be produced
Ovum, sperm drainage, and complete to be fertilized, fertilized eggs hatched seedling through 48-36 hours.
The conditions such as the present invention solves water temperature stability needed for snakehead breeds hatch fish roe, water quality is pure and fresh, dissolved oxygen is sufficient, it is micro-
Water flow stimulates parent population gonad development, is conducive to ovulate sperm drainage raising spawning rate, fertility rate and hatchability.To acquirement data and hydrostatic
Hatching is compared, and carries out data statistic analysis with statistical software.It the results are shown in Table 1, table 2, ecological flowing water breeding is bred with conventional
Compare, under identical water temperature condition, the extremely significant Effect time (P < 0.01) for reducing parent of ecology breeding energy, extremely significant raising parent
The spawning rate of fish, rate of fertilization (P < 0.01) significantly improve the hatching rate (P < 0.05) of fertilized eggs.
1 ecology breeding of table is compared with routinely breeding is to snakehead spawning effect
Note: colleague, which compares P<0.05, indicates that significant difference, P<0.01 indicate that difference is extremely significant, and P>0.05 indicates that difference is not shown
It writes, similarly hereinafter.
2 ecology breeding of table is compared with routinely breeding is to snakehead reproductive performance
