Description

A kind of flowing water culture method of Anguillar japonica
Technical field
The present invention relates to aquaculture, particularly relate to the flowing water culture method of Anguillar japonica.
Background technology
Anguillar japonica also known as Chinese yellow eel, is a kind of outward appearance Fish of being similar to that strip is snakelike, has the basic feature of fish.In addition Anguillar japonica and salmon Fish seemingly have migration characteristic, and Anguillar japonica belongs to Fish, like Serpentis, but without squama, typically originate in marine site, salt-fresh water boundary, migrate Fish birth At freshet, enter ocean afterwards, return again to freshet when they are grown up and lay eggs.And Anguillar japonica is in contrast, they Laying eggs in the seawater, small fish only has finger length and cannot differentiate sex, just in inflow stream, tells until growing to adult body Sex.After several years, they again return to ocean and carry out mate and oviposit.
It is badly in need of a kind of flowing water culture method of Anguillar japonica in the market.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of flowing water culture method of Anguillar japonica.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide the flowing water culture of a kind of Anguillar japonica Method, comprises the following steps: the construction in (1) pond, first finds the river of running water, builds many at river near the position on bank Individual square or rectangular fish culture in net pen pond, and net cage is provided with aerator and device for feeding fish bait, build indoor on the coast Plant;
(2) selection of Anguillar japonica Seedling, the specification selecting Anguillar japonica Seedling is 30~50 tails/jin, and breeding density is that every 5 square metres of waters surface put eel Seedling about 80-100 tail, before eel Seedling enters the pool, uniformly can throw something and feed in the range of Quan Tang running water flea or blood worm, net cage is provided with bait Platform, the top of bait table is provided with the bulb of 200 watts;
(3) Anguillar japonica food, feedstuff adds water and mixes dough and throw something and feed, and the ratio of dry powder and water is 1:1.2 when being Anguillar japonica Seedling, Anguillar japonica Seedling Gradually changing, Feeding time divides early, evening throws something and feeds for twice the most again, feeding volume mainly according to Feeding Velocity, dynamics and water quality, Changes in weather sees that food adjusts every day;
(4) pond water quality management and control, water disinfection mainly based on chlorine dioxide of splashing, after raining, add water after general with titanium dioxide Chlorine regulating water quality, finds that in water, zooplankton destroys water quality, i.e. kills with insecticide, the water quality requirement every liter water-soluble oxygen 8 in pond More than Hao Ke, water transparence is at 40 cm, and ammonia nitrogen content is below 2 mg/kg, and content of nitrite is 0.2 Milligram;
(5) Anguillar japonica is ripe, during Anguillar japonica maturation, can be regained together by net cage, then Anguillar japonica carries out the classification of size specification.
In a preferred embodiment of the present invention, after step (3) Anguillar japonica Seedling becomes greatly, flour is 1:1 with the ratio of water.
In a preferred embodiment of the present invention, step (1) outdoor temperature too high or too low time Anguillar japonica all need to be moved Move indoor culture.
The invention has the beneficial effects as follows: the flowing water culture method of Anguillar japonica of the present invention, this cultural method whole process uses running water to support Anguillar japonica is cultivated by the mode grown, it is not necessary to change water, simple to operate, improves income and the yield of cultivation.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described enforcement Example is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, this area is common All other embodiments that technical staff is obtained under not making creative work premise, broadly fall into the model of present invention protection Enclose.
A kind of flowing water culture method of Anguillar japonica, comprises the following steps: the construction in (1) pond, first finds the river of running water, Build multiple square or rectangular fish culture in net pen pond near the position on bank at river, and net cage is provided with aerator And device for feeding fish bait, build the plant of indoor on the coast, flowing water culture in breeding process without more renewing water, and oxygen content ratio Height is wanted in fishpond cultivation;
(2) selection of Anguillar japonica Seedling, the specification selecting Anguillar japonica Seedling is 30~50 tails/jin, and breeding density is that every 5 square metres of waters surface put eel Seedling about 80-100 tail, before eel Seedling enters the pool, uniformly can throw something and feed in the range of Quan Tang running water flea or blood worm, net cage is provided with bait Platform, the top of bait table is provided with the bulb of 200 watts, tempers the ingestion ability of Anguillar japonica Seedling;
(3) Anguillar japonica food, feedstuff adds water and mixes dough and throw something and feed, and the ratio of dry powder and water is 1:1.2 when being Anguillar japonica Seedling, Anguillar japonica Seedling Gradually changing, Feeding time divides early, evening throws something and feeds for twice the most again, feeding volume mainly according to Feeding Velocity, dynamics and water quality, Changes in weather sees that food adjusts every day;
(4) pond water quality management and control, water disinfection mainly based on chlorine dioxide of splashing, after raining, add water after general with titanium dioxide Chlorine regulating water quality, finds that in water, zooplankton destroys water quality, i.e. kills with insecticide, the water quality requirement every liter water-soluble oxygen 8 in pond More than Hao Ke, water transparence is at 40 cm, and ammonia nitrogen content is below 2 mg/kg, and content of nitrite is 0.2 Milligram, the situation that the management and control of water quality is fallen ill during can effectively controlling fish growth occurs;
(5) Anguillar japonica is ripe, during Anguillar japonica maturation, can be regained together by net cage, then Anguillar japonica carries out the classification of size specification.
In a preferred embodiment of the present invention, after step (3) Anguillar japonica Seedling becomes greatly, flour is 1:1 with the ratio of water.
In a preferred embodiment of the present invention, step (1) outdoor temperature too high or too low time Anguillar japonica all need to be moved Moving indoor culture, Fish easy anoxia when room temperature is too high, when room temperature is too low, the easy food ration of Fish tails off.
The flowing water culture method of Anguillar japonica of the present invention, solves the defect in technical scheme, and this cultural method whole process uses lives Anguillar japonica is cultivated by the mode of water cultivation, it is not necessary to change water, simple to operate, improves income and the yield of cultivation.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this Equivalent structure or equivalence flow process that bright description is made convert, or are directly or indirectly used in other relevant technology necks Territory, is the most in like manner included in the scope of patent protection of the present invention.
