Abstract
The invention relates to the technical field of aquaculture, in particular to the field of finless ell breeding. The high-efficient, intensive and ecological finless ell breeding method comprises the following steps that sterilization is conducted on a pond and a net cage; the net cage is hung to cultivate aquatic plants, and crucian and chub are bred in the pond; artificially-cultivated finless ell seedlings are selected and put into the net cage to be bred; live fly maggots or earthworms are thrown into the pond during the breed cultivation process to be used as bait; the finless ell is bred in a two-year period, and grown finless ell is collected to appear on market. The high-efficient, intensive and ecological finless ell breeding method has the advantages of being capable of improving water quality, improving the quality and value of the finless ell, and prompting the bait breeding industry and the downstream derivative products at the same time.
Description
Technical field
The present invention relates to a kind of technical field of aquaculture, particularly the method for a kind of efficient, intensive, ecologic breeding swamp eel.
Background technology
Swamp eel has another name called yellow eel, fine and tender taste, and delicious flavour, spur is few, contains rich in protein, multivitamin and mineral matter; Also being rich in DHA, EPA and other medicinal ingredient in the swamp eel body, having tonifying Qi, enrich blood, effect such as anti-inflammatory, sterilization, dispeling wind and dehumidification, is delicious food and the nourishing health-care food that liked by domestic and international consumer.In one's favour day by day on the market at home and abroad at present, nearly 3,000,000 tons of domestic market annual requirement, Japan, Korea S is annual to need 200,000 tons of imports, and the demand of Hong Kong and Macao also shows a rising trend.The main source of goods in supply swamp eel market is supported from wild fishing for the wild eel anti-season grain bin of some at present, is difficult to satisfy the demand in market, and this needs propagate artificially on a large scale swamp eel.
Current cultural method mainly is that to utilize cage culture, cage culture be the breeding way of a small investment, instant effect, convenient management, and the person generally adopts by culture of swamp eel.But traditional cage culture also exists a lot of deficiencies: mesh easily stops up to be needed often to clean, and workload is big; Remaining feed and the excreta of swamp eel can be accumulated in the net cage, and the time one is long, can produce niff, is unfavorable for the growth of swamp eel; Feed is cultured swamp eel, cause the swamp eel meat to descend, also environment is caused certain pollution simultaneously, and the yellow eel biological engineering does not finish as yet now, the eel kind all is wild fishing for, how to take full advantage of current wild eel kind resource, and excavate the more downstream derived product of high value, also become a major challenge of culture of swamp eel industry.
Summary of the invention
The object of the present invention is to provide the method for a kind of efficient, intensive, ecologic breeding swamp eel, can overcome the above-mentioned deficiency of existing cage culture method, can also solve and avoid buying the yellow eel peak period, reduce cost, take full advantage of wild eel kind resource simultaneously, create more being worth.
For achieving the above object, the present invention adopts following technical scheme:
The method of a kind of efficient, intensive, ecologic breeding swamp eel, it may further comprise the steps: (1) carries out disinfection to pond and net cage; (2) the linked network case is cultivated pasture and water, puts live body feed one in a suitable place to breed in the pond simultaneously; (3) select the swamp eel seedling, put into cage culture; (4) throw in live body feed two in the breeding process as bait; (5) swamp eel survives the winter naturally; (6) throw in live body feed two in the breeding process as bait; (7) gather in the crops into the eel listing.
As preferably, described step (1) was carried out in April; Step (2) was carried out in May; Step (3) is carried out at the beginning of by the end of June to 7 months; Step (4) in July first arrival carry out October; Step (5) was carried out in the April of October to next year; Step (6) was carried out in the October of April to the next year of next year; (7) carry out in October.
As preferably, described swamp eel seedling is deep yellow big spot eel or golden yellow stigma eel.
As preferably, the body weight of described swamp eel seedling is 50-60 gram/bar.
Avoid 4 by implementing this technical scheme, swamp eel physique in the May more weak and period of pregnancy that should not move, the swamp eel seedling is more suitable for transportation, survival rate is higher.
As preferably, described live body feed one is shrimp, crucian, silver carp.
By implementing the technical program, shrimp, carp and silver carp can digest relevant residue, residual bait, avoid water pollution; Shrimp, carp and silver carp can be used as the fresh animal bait of swamp eel again; Shrimp, carp and silver carp can also have considerable economic value as the downstream derived product.
As preferably, described live body feed two is earthworm, fly maggot.
By implementing the technical program, can strengthen the amount of exercise of swamp eel, promote the quality of swamp eel.
As preferably, described swamp eel seedling is put in a suitable place to breed with every square metre of 2-3 kilogram.
By implementing this technical scheme, the net cage space is more suitable for the swamp eel growth, also is easy to control the disease of swamp eel.
As preferably, the pasture and water of cultivating in described net cage are water peanut.
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, the pasture and water of cultivating in the described net cage are provided with the food platform, make things convenient for swamp eel to get food, also can reduce the waste of feed.
As preferably, the time of described feeding is 5-6 point at dusk.
Swamp eel is nocturnalism, so the dusk feeding is fit to the life habit of swamp eel, has also guaranteed the freshness of food when swamp eel is edible.
As preferably, the weight of the described feed of at every turn throwing something and feeding is the 4%-5% of swamp eel gross weight.Along with the approximately weekly forage volume that increases of the growth of swamp eel, guarantee that forage volume is the 4%-5% of swamp eel gross weight.
As preferably, the weight of the described feed of at every turn throwing something and feeding 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 method of ecologic breeding swamp eel of the present invention has following beneficial effect: adopt the fish, fly maggot or the earthworm that live as bait among the present invention, can promote swamp eel quality and value, can also drive the bait aquaculture simultaneously.Swamp eel and shrimp, carp and silver carp cover are supported, and have not only solved obstruction and residual feed and the swamp eel excreta problem of mesh, the product in a series of downstream of also having derived.Swamp eel is cultured through 2 years sections, can grow up to the higher one-tenth eel of value, and its meat can compare favourably with wild eel, has also avoided purchase yellow eel peak period, reduces cost, for the culturist creates more value.
