Abstract
The invention relates to the field of finless eel breeding, in particular to a method for breeding finless eels in a two-year period. The method includes the steps of (1) disinfecting a pond and net cages in April, (2) hanging the net cages in May, (3) picking manually cultured finless eel fry from the early June to the early July and putting the finless eel fry into the net cages for breeding, (4) putting bait in the early July for breeding, (5) allowing the finless eels to naturally pass a winter from October to the next April, (6) putting bait in the next April for breeding, and (7) harvesting the finless eels for sales in the next October. According to the method, a peak season of buying wide finless eel fry and the egg stage of the finless eels can be avoided, cost is reduced, the survival rate is improved, the finless eel breeding specification is improved, and quality and value of the finless eels are improved.
Description
Technical field
The present invention relates to a kind of culture of swamp eel field, particularly the method for a kind of 2 years section breed swamp eels.
Background technology
The swamp eel delicious meat, be of high nutritive value, the consumer is to being in great demand of swamp eel both at home and abroad, and grows with each passing day, and limited wild resource can not be met the need of market far away.The culture of swamp eel industry is also along with the demand in market is progressively risen at present.But swamp eel the biological engineering do not finish as yet, and the eel seedling all
Fish for for wild, so wild swamp eel resource also reduces gradually.
Current because swamp eel value height adds that the culturist does not have experience, cultured about 1 year so swamp eel is general, just sale.But because wild swamp eel lives under the nature for a long time, mainly the hydroplankton based on predation live fish, live shrimp, tadpole, water earthworm is food, artificial large-scale farming is difficult to reach these conditions, just need the domestication swamp eel to eat artifical compound feed, swamp eel has just entered in the net cage and has raised, be difficult to conform, need slowly to adapt to for a long time to change, the edible artifical compound feed of domestication swamp eel also takes time, so little eel did not reach best weight in 1 year, the culturist does not obtain the highest value yet.And 1 year breeding method, its purchase the seedling time generally every year 4, May, this moment, swamp eel was in the bosom ovum phase, can strengthen its lethality in the transportation.How can allow these limited wild swamp eel resources bring into play maximum values, for the consumer provides better more swamp eel food, for the culturist brings better economic benefit, perplex vast culturist always.
Summary of the invention
The invention provides the method for a kind of 2 years section breed swamp eels, can address the above problem, can also avoid buying simultaneously the peak period of wild eel seedling, reduce cost.
For achieving the above object, the technical solution used in the present invention is as follows: a kind of 2 years sections are cultured the method for swamp eel, and may further comprise the steps: carry out disinfection to pond and net cage (1) April; (2) May the linked network case; (3) select the swamp eel seedling of artificial culture by the end of June at the beginning of 7 months, put into cage culture; Throw in bait at the beginning of (4) 7 months, culture; (5) allow it survive the winter naturally April October to next year; (6) throw in bait April next year, culture; (7) gather in the crops into the eel listing October next year.
Put the swamp eel seedling in the technical scheme in a suitable place to breed and at the beginning of by the end of June to 7 months, carry out, can avoid culturing in 1 year 4, buy the peak period of swamp eel seedling May, purchase the seedling cost and reduce, and 4, May swamp eel be in the fragile bosom ovum phase, transportation is big to its injury, survival rate is low; Culturing through 2 years sections, become eel can reach the 300-500g/ bar, is the specification that the eel seedling has reached the market demand basically, the market price height, and also meat is also equally matched with wild eel.
As preferably, culture pasture and water on the described net cage.
By implementing the technical program, can effectively regulate and purify water, provide the place of having a rest and shading to swamp eel simultaneously.
As preferably, described swamp eel seedling is deep yellow big spot eel or golden yellow stigma eel.
As preferably, the 5-6 o'clock that the described input bait time is every afternoon.
Swamp eel is nocturnalism, so the dusk feeding is fit to the life habit of swamp eel.
As preferably, the weight of described each input bait is the 4%-5% of swamp eel gross weight.
As preferably, the weight of described each input bait is 5% of swamp eel gross weight.
By implementing this technical scheme, be unlikely to excessive or not enough after the swamp eel feed, be more suitable for its growth.
The present invention adopts technique scheme, has following effect: can avoid buying the peak period of wild eel seedling, reduce cost, improve survival rate; 2 years sections are cultured and have been improved eel specification, the quality that has promoted swamp eel and value.
Embodiment
Embodiment 1:
After April pond and net cage being carried out disinfection, May is the linked network case in the pond, and 1.5 meters at interval in each net cage is cultivated water peanut in the net cage, improve swamp eel living environment, also for it provides the place of shading of having a rest, puts shrimp, crucian and silver carp simultaneously in a suitable place to breed in the pond; Selecting body weight by the end of June is 50-60 gram/bar, healthy, do not have hinder, anosis deep yellow big spot eel seedling, put in a suitable place to breed by 3 kilograms every square metre, 5-6 o'clock every afternoon feeds, 0.05 kilogram of feed of per kilogram swamp eel nursing; Enter winter by the end of October, water level be increased to 55 centimeters, and in the insulation of yellow eel pond loam cake last layer white overlay, allow yellow eel survive the winter smoothly, during need not feed; At the beginning of 4 months next years, temperature gos up to begin feeding, to fishing for listing by the end of October.Often check the situation of swamp eel during this time.
Embodiment 2:
Different with above-described embodiment be in April pond and net cage are carried out disinfection after, May is the linked network case in the pond, 1.5 meters at interval in each net cage, cultivate water peanut in the net cage, improve swamp eel living environment, also for it provides the place of shading of having a rest, in the pond, put shrimp, crucian and silver carp simultaneously in a suitable place to breed; Selecting body weight by the end of June is 50-60 gram/bar, healthy, do not have hinder, anosis deep yellow big spot eel seedling, put in a suitable place to breed by every square metre of 2-2.5 kilogram, 5-6 o'clock every afternoon feeds, 0.04 kilogram of feed of per kilogram swamp eel nursing; Enter winter by the end of October, water level be increased to 55 centimeters, and in the insulation of yellow eel pond loam cake last layer white overlay, allow yellow eel survive the winter smoothly, during need not feed; At the beginning of 4 months next years, temperature gos up to begin feeding, to fishing for listing by the end of October.Often check the situation of swamp eel during this time.
By implementing above-described embodiment, can avoid buying the peak period of wild eel seedling, reduce cost, improve survival rate; 2 years sections are cultured and have been improved eel specification, the quality that has promoted swamp eel and value.
