Description
Technical field
The invention belongs to technical field of aquaculture, be specifically related to the breeding method of a kind of loach fry maintenance phase.
Background technology
Loach is under the jurisdiction of Cypriniformes, Cobitidae, flower loach subfamily, loach genus on taxonomy.Loach is distributed widely in various places, Asia, and all there is more distribution in China to the ground such as Burma and Japan.Loach mainly inhabits the soft waters of the substrates such as river, irrigation canals and ditches and rice field.The next mouth of Misgurnus Anguillicaudatus, being demersal fishes, is typically eat corruption fish.Loach is omnivorousness, and the loach of long below the 5cm of body mainly ingests small-sized shell-fish and plankton, along with the increase that body is long, transfers inclined phytophagy gradually to.Loach is comparatively responsive to sex hormone, its artificial propagation techniques also comparative maturity.The dressed fish of loach is 65.954%, and protein content reaches about 17%, and nutritive value is considerable.But people pay close attention to the nutritive value of a lot of not loach, but its medical value.Have research think loach to hepatitis, osteomyelitis and other inflammation even cancer there is certain medical function.Successively the active substance that agglutinin, deamination neuraminic acid GL-PP, antibacterial peptide, immune polysaccharide etc. have medical value has been extracted in loach body and in mucus, Loach Protein hydrolysate has very strong oxidation resistance, can remove the free radical in body.As can be seen here, the using value of loach is higher, thus also have stimulated the development of loach breeding industry to a certain extent.
Along with the expansion of loach range of application, market is also expanding the demand of loach, but the quantity of its Natural Population cannot meet the demand in market.Propagate the solution that loach is best beyond doubt artificially.Although the artificial propagation techniques of loach is ripe, the low survival rate in loach fry stage becomes the bottleneck that loach is propagated artificially.And the research that relevant loach fry is cultivated is still few.Relevant report is rarely seen combines and throws something and feeds on loach larvae growth and the impact of survival and the f eeding rhythm of loach prelarva.With regard to the development that loach is propagated artificially, be badly in need of a series of loach fry Cultivating techniques now, to improve weed survival rate, for loach breeding industry lays the foundation.
Summary of the invention
The present invention, in order to solve the problems of the technologies described above, provides the breeding method of a kind of loach fry maintenance phase, and what propose loach fry cultivation most junior three week needs special maintenance, i.e. the maintenance phase concept of loach fry.The maintenance phase is the critical period that loach fry is cultivated, and this, survival rate of loach fry was usually very low in period, and has to pass through special maintenance and just can significantly improve.Therefore, by the cultivation facility of the biology of research maintenance phase loach, seed, put that technology, food organisms are supporting in a suitable place to breed, the harm of harmful organisms and prevention and controls etc., establish the breeding method of the present invention's a kind of loach fry maintenance phase.
In order to reach above-mentioned technique effect, technical scheme of the present invention comprises:
The breeding method of loach fry maintenance phase, comprises the following steps:
Step one: loach fry cultivates the design in pond: described cultivation pond is rectangle Tu Chi, area 100m
2, dark 0.7m, mud degree of depth 15cm at the bottom of pond, be provided with aerator in described cultivation pond, cultivate pond for every mu and throw in 10 kilograms of bio-bacterial manures, described cultivation pond is provided with water inlet and delivery port, described water inlet and water outlet are provided with water strainer, and cultivation pond surrounding is provided with loach and prevents escaping net;
Step 2: putting in a suitable place to breed of loach fry: cultivate pond temperature at 20 DEG C ~ 26 DEG C, the loach water flower that same batch of selection, 2 ~ 3 ages in days start flat trip is put in a suitable place to breed, and breeding density is 20 ~ 300,000 tails/665m
2;
Step 3: the preparation of bait and nursing: get that parts by weight are the earthworm of 10 ~ 30 parts, 5 ~ 20 portions of yellow mealworms, 17 ~ 25 parts of flour, 1 ~ 5 portion of edible oil be ground into 80 ~ 100 order micro mists and obtain after stirring, be the adhesive mixing of 1 ~ 5 part with parts by weight by described micro mist, make the granular bait for fish of 1.6 ~ 2.0mm size, described granular bait for fish is fed as feed, feeding volume is every day 3 times, each 2 ~ 3 kilograms;
Step 4: the control of harmful organisms: at the bird prevention net of described cultivation pond surrounding erection 15 × 15cm mesh size, simultaneously kill the batrachia young in pond.
Described bio-bacterial manure is EM bacterium.
Described loach prevents that escaping net is 50 order meshes.
Beneficial effect of the present invention comprises:
The breeding method of a kind of loach fry maintenance phase provided by the invention, studies the biology of loach fry maintenance phase, ecology and behaviouristics, understands the basic data of loach fry, cultivates lay a solid foundation for loach fry.On this basis, set up the maintenance facility of several loach fry, ensure the survival rate of loach fry.Design several breeding density, put the time in a suitable place to breed and put strategy etc. in a suitable place to breed, by the cultivation of maintenance phase, detect the growth of loach fry, survival rate and biological differences, what draw the best puts technology in a suitable place to breed.Design the fertilizer applications that several are different, the cultivation situation of food organisms under comparison Different Fertilization scheme, primary evaluation index has peak period time of occurrence, the continuation of agreeable to the taste food organisms, diet biomass, food organisms sociales etc., determine best food organisms cultivate mode with this.The harmful organisms (dragonfly Yan larva, predacious diving beetle and larva, Trichodina and oblique tube insect etc.) that the observation loach maintenance phase occurs, design different pharmaceutical formula, carry out harmful organisms and loach prelarva to medicament sensitivity test, ensure that medicine has very high killing action can ensure the safety of loach prelarva to harmful organisms simultaneously.
