Abstract
The invention discloses a method for incubating oriental weatherfish, which includes steps: firstly, preparing cement ponds and culture ponds, using at least one cement pond as a spawning pond to be disinfected, using at least two culture ponds as incubating ponds to be disinfected, and using at least one culture pond as water fertilizing pond to be fertilized with water; secondly putting parent fishes into the disinfected cement ponds for the parent fishes to lay eggs; thirdly, putting fertilized eggs obtained in the step 2 into the incubating ponds mentioned in the step 1; fourthly, when young fishes start swim 4-5 days after incubation, using bolting silk to filter the water in the water fertilizing ponds mentioned in the step 1 and adding the water into the incubating ponds, and transferring the young fishes in the cement ponds into the water fertilizing ponds; and fifthly, conventionally incubating the young fishes in all of the incubating ponds and the water fertilizing ponds, and breeding the fishes by the conventional method. The method for incubating oriental weatherfish reduces use of the cement ponds and solves the problem of undersupply of incubating facilities, and by the method, incubating survival rate is up to 50%, and the results are unexpected.
Description
Technical field
The present invention relates to the hatching breeding method of a kind of fish, be specifically related to the hatching breeding method of a kind of loach, realize hatching and the summer flower fish fry breeding of loach.
Background technology
Loach is described as " genseng in the water ", its delicious flavour, fine and tender taste, nutritious.According to one's analysis, contain protein 18.4 gram, fat 2.9 grams in every hectogram loach meat, vitamin B1, A, C content are all higher than other fish.In addition, loach property is flat, flavor is sweet, go into liver spleen kidney, pharmaceutically also has higher value, and therefore, loach export trade amount increases year by year in recent years, and the consumption figure of domestic loach is also in rising trend.
Because natural loach resource far can not satisfy people's consumption demand, so the loach aquaculture also begins to have entered the fast-developing phase.Simultaneously, loach is strong because of its adaptability, disease is few, survival rate is high, bait is easy to get, and has become important aquaculture object.2011, mu loach fishing breeding pond surplus only Jiangsu Province just has 30,000, the output value is above 1,000,000,000 yuan.
In recent years, Chinese scholars has been carried out certain research to the loach artificial culture, and its artificial propagation techniques has had breakthrough.Existing loach hatching breeding method is: the loach parent population is positioned in the prior cement pit of sterilizing lays eggs, the fertilized egg of giving birth to continuation hatches into the loach seedling in cement pit, after treating the flat trip of fry, the pond (be commonly called as and be " pool of growing dim ") that fry is transferred to behind prior rich water is cultivated, about 1 month, cultivate into specification more than 3 centimetres (be commonly called as " summer flower fingerling), about 5 months; loach grow to 5 grams/about, be the loach large size fingerling.
Yet there are the following problems for above-mentioned breeding method: all carry out cement pit to the flat trip of fry owing to laying eggs from the loach parent population (1), and therefore one batch of loach of every cultivation all will take a large amount of cement pits; And laying eggs from parent population on average needs 5 day time to the flat trip of loach seedling, and a collection of parent population of namely whenever hastening parturition all will take the hatching at least 5 days time of facility, therefore need take a large amount of cement pits, serious waste of resources; (2) in the process in the cultivation pond (also claiming the rich water pond) after the fry (being commonly called as " spray ") that will put down trip is transferred to rich water, it is injured or dead fry inevitably can to occur, and then has influenced cultivating survival rate; And the amount of labour that should operate is bigger.
Summary of the invention
The object of the invention provides the hatching breeding method of a kind of loach, to improve loach artificial propagation efficient and cultivating survival rate.
For achieving the above object, the technical solution used in the present invention is: the hatching breeding method of a kind of loach comprises the steps:
(1) prepare in cement pit and pond: at least 1 cement pit is carried out disinfection as spawning pond; Will 2 cultivate ponds at least as the sterilization of cleaning up the pond of hatching pond; Rich water is carried out as the rich water pond at least 1 cultivation pond;
(2) put into parent population in the cement pit after above-mentioned sterilization, lay eggs;
(3) fertilized egg that step (2) is obtained is partly rendered in the described hatching of step (1) pond, and to make the density of the fertilized egg in the hatching pond be 20 ~ 300,000 ovum/667 square metre; Remaining fertilized egg is stayed directly hatching in the former cement pit;
(4) hatching is after 4 ~ 5 days, and the loach seedling begins flat trip, the water in the described rich water of step (1) pond is mended behind the silk cover filtering after filtration gone into to hatch the pond, makes the wheel animalcule density in the hatching pond remain on 10 ~ 20/milliliter; The order number of described filtration bolting silk is 10 ~ 20 orders;
Simultaneously the loach seedling in the cement pit is transferred in the rich water pond, and made fry density in the rich water pond remain on 15 ~ 200,000 tail/667 square metre;
(5) in above-mentioned all hatching ponds and rich water pond, carry out the routine operation of growing dim, cultivate according to conventional method then.
Above, the described sterilization of cleaning up the pond is prior art, as adopting the bleaching powder sterilization of cleaning up the pond.Described rich water also is prior art, carries out rich water as can apply the fertilizer that fermented through becoming thoroughly decomposed in the pond.
Optimized technical scheme, described cement pit are 1, and the pond as the hatching pond, is cultivated as the rich water pond with 1 in 4 cultivation ponds.Namely cultivate the pond with 5 and add 1 cement pit as a combined operation group, existing pond can be adopted in described cultivation pond.
In the technique scheme, the rich water pond in the described step (1) is the sterilization of cleaning up the pond in 7 ~ 10 days before artificial induced spawning, executes the fertilizer that fermented through becoming thoroughly decomposed then and carries out rich water, and its consumption is 140 ~ 160 kilograms/667 square metres.
In the technique scheme, the hatching pond in the described step (1) is in the artificial induced spawning sterilization of cleaning up the pond in preceding 4 days.And do not carry out rich water.
Because technique scheme is used, the present invention compared with prior art has following advantage:
1. the present invention has developed the hatching breeding method of a kind of new loach, can cultivate ponds with 5 and add 1 cement pit and cultivate a collection of loach as a combined operation group; Obviously, this method has significantly reduced the usage amount of cement pit, has solved the problem of hatching facility anxiety, thereby has had active operation significance.
2. hatching breeding method of the present invention uses the cement pit of sterilization and hatching pond to hatch in early stage, hatching water quality is salubrious, improved incubation rate, later stage mends into the hatching pond from the moisturizing of rich water pond, directly the agreeable to the taste bait of loach seedling such as wheel animalcule are replenished and enter the hatching pond, thereby improved the early stage survival rate of loach seedling; Evidence: the cultivating survival rate of breeding method of the present invention is up to 50%, compares existing 20% cultivating survival rate and is greatly improved, and has beyond thought effect.
3. the present invention compares existing mobile fry (being commonly called as " spray ") by evenly the distribute cultivation quantity in each pond of mobile fertilized egg, greatly reduces the amount of labour, has improved operating efficiency, also is conducive to improve simultaneously cultivating survival rate.
4. breeding method of the present invention is simple, and is easy and simple to handle, is suitable for applying.
