Description
Art
The present invention relates to cultivator field, be specifically related to a kind of efficient swamp eel breeding net cage, also relate to a kind of erection method of efficient swamp eel breeding net cage and a kind of using method of efficient swamp eel breeding net cage, be applicable to the cultivation of swamp eel.
Background technology
Swamp eel (Monopterusalbus) is subtropics fish, has another name called yellow eel, sieve fish, field eel, Changyu, Huang Can, without squama son, Tian Can etc., is under the jurisdiction of Symbranchir, He Sai section; In Symbranchir, the whole world only has a kind, i.e. swamp eel.Be distributed widely in the Japan in Southeast Asia, Thailand, Indonesia, Philippine, Malaysia, India, Japan, Korea and China etc., all there is distribution in China except Qinghai-Tibet Platean, and especially with In Middle And Lower Reaches of Changjiang River, distribution density is large, output is high, is a kind of important economic fish.
The artificial propagation mode of swamp eel mainly contains natural spawning, artificial induced spawning under manual control condition, artificial insemination and artificial induced spawning, 3 kinds of modes such as natural spawning.Wherein, artificial induced spawning, artificial insemination and artificial induced spawning, these two kinds of modes of natural spawning due to fertilization rate low, the reasons such as parent population damage is serious, and effect of laying eggs is unstable, seldom adopt in swamp eel propagation in scale.It is at present, main that what adopt is natural spawning under manual control condition.
According to the difference of egg-laying environment, the natural spawning under manual control condition can be divided into again great Chi extensive natural spawning, small-sized net cage Ecology natural spawning and small-sized net cage without native natural spawning three kinds of modes.
The extensive natural spawning of great Chi builds the low bank of earth between fields in pond, water surface planting water plants, and close eel is put in a suitable place to breed by a certain percentage in pond, after swamp eel lays eggs, collects fertilized egg and carry out artificial incubation.The method due to spawning rate low, seedling incubation rate is low, parent population reclaim difficulty etc. reason, substantially do not adopt at present.
Small-sized net cage Ecology natural spawning is erected in pond by the net cage of 1 to 1.5 square metres, 20cm is had to imbed in the subsoil of pond bottom net cage, the water plants such as the pond depth of water controls at 10 ~ 15cm, net cage water surface planting weter hyacinth, parent population female-male proportion is put in a suitable place to breed in each net cage by 4:2.After swamp eel lays eggs, or naturally hatch on the spot, or collection ovum carries out artificial incubation.This adopts maximum a kind of artificial propagation modes at present.Although adopt the method tentatively can realize the large-scale artificial breeding of swamp eel, spawning rate is also more stable, can breed 20 ~ 300,000 tail seeds for every mu every year.But required technology content is higher, more difficult to the control of collection seedling, not easily apply.Labor cost is too high, and a people can only manage at most about 1000 young net cages, and large-scale degree is very limited.And parent population reclaims difficulty, and the rate of recovery of parent population can only accomplish about 70%.
Small-sized net cage, without the native natural spawning breeding erection of net cage and the substantially identical of small-sized net cage Ecology natural spawning, be not embedded in soil unlike net cage, be placed directly on bottom surface, pond.The feature of this propagation method is convenient to parent population reclaim, and increases number of times of laying eggs, thus the fry output of unit are is increased.But the method is easily subject to the impact of weather, the risk that stress reaction occurs close eel is comparatively large, and thus spawning rate is unstable.
Summary of the invention
Object of the present invention; be the defect overcoming prior art; there is provided and relate to a kind of efficient swamp eel breeding net cage; the using method of a kind of erection method of efficient swamp eel breeding net cage and a kind of efficient swamp eel breeding net cage is also provided; effectively improve the spawning rate of swamp eel unit are, increase substantially the degree of swamp eel biological control.
The present invention is achieved through the following technical solutions:
1, net cage band structure is bred
Fig. 1 is the vertical view of swamp eel breeding net cage, and Fig. 2 is the end view of swamp eel breeding net cage.
Net cage comprises at the bottom of pond, also comprises and being arranged at the bottom of pond and the pillar of rectangular distribution, surround rectangle net wall by net and pillar at Chi Dishang.
Net cage is long, wide, and height is respectively: 0.8 ~ 1.2 meter, 0.8 ~ 1.2 meter, 0.8 meter.Mesh is 8 orders.
A retaining wall respectively built by 3 ~ 5 layers of brick in net cage two diagonal angle, entered by mound in the diagonal angle separated by retaining wall, and retaining wall is high 0.3 ~ 0.5 meter.
Retaining wall adopts the method (shown in Fig. 3) misplacing and build a wall, and the distance between every layer of brick and brick keeps 5 ~ 7 centimetres, forms retaining wall hole, facilitates swamp eel to creep into and get out.
Between two mounds, the center of net cage, puts 3 ~ 5 weter hyacinths, or the brown handle that 1 brown sheet is pricked, and as artificial fish nest, swamp eel can lay eggs herein from now on.
2, the erection of net cage band is bred
1) by the bottom leveling in breeding pond;
2) dig wide 0.8 ~ 1.2 meter along breeding north-south, pond, row's ditch of dark 0.3 ~ 0.5 meter, except 2 row's ditches on most limit, pond, every 2 rows of middle row's ditch are 1 group and are close together, and the distance between each group row ditch is 1.5 meters, walkway when operating as breeding;
3) upper end, each net cage corner is fixed on the pillar that makes of bamboo pole, and adjacent two net cages share pillar;
4) mound of the adjacent net cage in each row's ditch is pressed mirror image and is stacked, and forms the sluice of a S shape in the middle of row's ditch.Namely often row breeds the sluice be divided into by retaining wall in breeding net cage adjacent in net cage band and connects into S shape (shown in Fig. 4).
3, breed net cage to use
1) annual early June, pond water to be down on the mound in net cage 10 ~ 20 centimetres.
2) after net cage sets up, the water in the pond of placing net cage is added to more than 1 meter, puts the grass carp of 1-2kg/ tail in a suitable place to breed, 100-150 tail/mu, in order to avoid pasture and water growth in breeding pond.
3) before parent population enters breeding net cage, each net cage spreads 0.05 ~ 0.1 kilogram of lime disinfection.After 3 days, water is changed 1 time in pond.
4) parent population is selected.Milter selects more than 150g, and skull swells, and belly is bloodshot.Raun selects belly obviously to expand, and is the bigger the better.
5) first 1 day of parent population pairing, center artificial fish nest being put into each net cage is fixed.Artificial fish nest is 3-5 weter hyacinth or 1 brown handle.
6) each net cage puts milter 1, raun 2.
7) to put after fish 20 ~ 25 days, pond water is deepened 20 centimetres on existing basis.
8) after 1 day, all artificial fish nests are packed up, put into the water tank cultivating swamp eel seedling and carry out training seedling.
9), after receiving seedling, 1 cage is put in each net cage center, and earthworm is put in face to cage.
10) within the 2nd day, receive cage, receive parent population, return parent population net cage and continue cultivation.
The present invention compared with prior art, has following beneficial effect:
1, the comparison of structure and erection method
1) net cage buries soil: the heap indigenous method that the present invention breeds net cage at the heap indigenous method of breeding in case and small-sized net cage Ecology has larger difference.Bottom the breeding net cage of Ecology, about 20 centimetres are all buried in the earth, swamp eel in net cage be from burrow toward oblique below.Soil of the present invention is two diagonal angles piling up net cage, and swamp eel is laterally burrow in net cage.This environment closer to swamp eel at natural egg-laying environment of nesting.And the parent population of Ecology breeding is reclaimed can only with manually being dug out from soil by swamp eel, and swamp eel of the present invention is reclaimed can place cage between two mounds, allows swamp eel pierce in cage, and such swamp eel parent population is reclaimed more convenient, and parent population damage is also less.
2) artificial fish nest: Ecology and the artificial fish nest without soil breeding are open, and fish nest will be paved with whole net cage, swamp eel oneself selects the fish nest be applicable to lay eggs in net cage.This mode determines time of swamp eel collection seedling must be very accurate, and early, survival rate of seedling can be greatly affected collection seedling.Collection Miao Wanliao, seedling can run loose, thus greatly reduces collection seedling rate.Artificial fish nest of the present invention is restraint-type, and only place a fish nest in the center of net cage, swamp eel can only lay eggs on this fish nest.This mode does not need the collection seedling time too accurate, even if several days evening collected seedling, seedling also can run nowhere, on collection seedling rate without any impact.Therefore, the breeding management of the present invention to swamp eel is more convenient, and collection seedling rate is higher, and labor cost is lower.
3) water coke slurry: Ecology and only have 10 ~ 20 centimetres high without the water in soil breeding net cage, when breeding pond area and being larger, is difficult to ensure that the water of each net cage can exchange to.And the present invention defines sluice in net cage, such current just can arrive each net cage, thus effectively raise the water environment in net cage.To the breeding of swamp eel, hatching, seedling survival is more favourable.
4) low bank of earth between fields: during with Ecology with without soil breeding net cage, owing to wanting the accurate perception collection seedling time, need the every day of laying eggs to each net cage, hatching situation is observed.Because people walks about on net cage limit back and forth, be easy to affect laying eggs of swamp eel in net cage.In order to address this problem, when set up net cage, 1 low bank of earth between fields can be repaiied often arranging between net cage, being convenient to walking and the observation of people, which reduces the net cage quantity of pond unit are.Adopt breeding net cage of the present invention, owing to not needing the accurate perception collection seedling time, also just eliminate the daily observation to each breeding case.Therefore, also just the low bank of earth between fields is not needed.So just substantially increase the quantity of pond unit are net cage.
2, the comparison of using method and effect
1) pairing and parent population are reclaimed: Ecology breeding is reclaimed to adopt due to parent population and cut the earth, and manually catch parent population, parent population reclaims difficulty, and annual each net cage only does 1 parent population pairing, generally presses sex ration 2:4 and matches.After having matched, according to statistics, what annual each net cage produced 1 deutovum is about 80%, and what produce 2 deutovums is about 40%, produce 3 deutovums less than 10%.Reclaim because parent population directly plays net cage without soil breeding, parent population is reclaimed convenient, and annual each net cage can do 2 ~ 3 pairings, each pairing sex ration 2:1.But because environmental condition is bad, after each pairing, spawning rate is lower, generally only has about 70%.The present invention adopts cage to reclaim parent population, and parent population is reclaimed also more convenient.Therefore, annual each net cage also can do 2 ~ 3 pairings, but compares with without native breeding, and because environmental condition improves a lot, each spawning rate all can arrive more than 95%.
2) seedling-growing method and labor cost is collected: Ecology and artificial fish nest open without soil breeding, swamp eel can may lay eggs in the optional position of net cage, if receive seedling not in time after seedling has hatched, seedling may go on any weter hyacinth of net cage.Therefore, only have by artificial continuous laying eggs to each net cage, the situations such as hatching are constantly observed, record, calculate the collection seedling time, effectively could improve collection seedling rate.This will spend a large amount of artificial, and usual 1 labour can only manage the net cage of about 1000.After adopting the present invention, because artificial fish nest is fixed, seedling can not run about, and does not therefore need the accurate perception collection seedling time.After can waiting until that nearly all net cage has produced ovum, disposable whole receipts seedling.Therefore, labor cost is greatly reduced.Adopt the present invention, each labour can manage the net cage of more than 10000.
Effectiveness comparison after the present invention and other method use is as following table:
