Description

The anti-escape fish of anti-natural enemy terraced fields cultivation cage

Technical field

The utility model is the fish culture apparatus under a kind of terraced fields shallow water condition, specifically the anti-escape fish of a kind of anti-natural enemy terraced fields cultivation cage.

Background technology

Terraced fields are step-like paddy fields that hillside fields shape opens up wasteland out near the mountain in mountain area, multiplexly plant the aquatic crops such as paddy rice, arrowhead, and subsidiary cultured fishes simultaneously, to increase the usefulness of utilizing in soil.Because terraced fields are to build by the mountain, different, not of uniform size, water layer is very shallow, and the fish that can cultivate are mostly small-sized fish.As heavy rain, mountain torrents, water in field is excessive, and fish is easily escaped, and causes damage to owner.When water is more shallow at ordinary times, fish is easy to again be preyed on by natural enemies such as eagle, aquatic bird, water snake and ducks, and result is that fish is not also formed, and the fish in field has remained little.These reasons cause terraced fields to be breeded fish not amounting to anything so far just, except minority area is larger, puts some fries in a suitable place to breed allow outside it runs its course as one mu of above field, and most of terraced fields are all to leave unused all the year round, and the potentiality of terraced fields resource are far from being brought into play.

Summary of the invention

The purpose of this utility model is exactly for the problems referred to above, the anti-escape fish of a kind of anti-natural enemy in mountain terraced fields cultivation cage is proposed, this cage can avoid the fish of putting in a suitable place to breed in terraced fields to be preyed on by eagle, aquatic bird, water snake and duck effectively, still idle time autumn and winter does not affect the growth and breedings of fish to spring and summer plantation crop, the output that improves and guarantee fish, solves with this problem that terraced fields utilization ratio is low.

The anti-escape fish of this anti-natural enemy terraced fields cultivation cage that the utility model proposes, it is characterized in that it is strip cylinder mould, be placed in the ditch of terraced fields, cylinder mould is made up of skeleton and outer net, outer net is wrapped in skeleton outside, there is the water surface of exceeding feeding mouth one end of cylinder mould, throws in fish meal to facilitate near ridge.

On feeding mouth, there is the slide fastener being connected with outer net, to close upper shed after throwing in feed, prevent that foreign matter from entering.

Described skeleton is square or circular, makes with materials such as iron wire, batten or plastic strips, and the cross dimension of skeleton and the cross section of trench adapt, to guarantee that cage is put into trench and convenience is taken out.

Quadrate framework cross section is of a size of 20 × 30cm, and the mud layer thickness of this size and existing most of terraced fields is suitable, is convenient to put in a suitable place to breed loach, swamp eel, catfish, the isometric body fish of snakeheaded fish.Certainly, the size of skeleton can be determined according to specific needs, if trench is darker, can strengthen skeleton size.The length of cage is determined according to the length of trench.

Described outer net is the nylon wire of 80-100 order left and right.Outer net is equivalent to the coat of skeleton, whole being wrapped on skeleton.

Outer net can only be enclosed within on the item face and wall face of skeleton.This cage is applicable to putting in a suitable place to breed of snakeheaded fish.

The utility model is to use like this: first in terraced fields, dig out a trench, as output wide 20cm, the trench of dark 30cm, at least one end of trench arrives ridge place, between each trench, be arranged in parallel, density plants crop according to Tanaka and determine season, and interval is not generally less than 2 meters.After trench is held successfully, whole cage is put into ditch and also guarantee to be immersed in the water completely, only allow feeding mouth exceed the water surface, now fry can be dropped in cage and puts in a suitable place to breed.

The management of breeding fish is undertaken by the general rules of breeding fish.Bring up need to gather in the crops time when fish, can stretch into and fish for from feeding mouth with tuck net, also whole cage can be taken out and be collected.As long as the water in terraced fields is dry, do not freeze, this cage throughout the year all can stocked carp, even can according to changes in market demand adjust stocked carp kind and batch, in the hope of maximizing the benefits, increase peasant household and take in.

The utility model is best suited for mountain area, and particularly the farmers' family in terraced fields area is used, and when field plantation cereal crops, stocked carp in cage, accomplishes that kind of grain is breeded fish to neglect neither.And this cage has thoroughly avoided Tanaka's fish by the problem of eagle, aquatic bird, water snake and duck etc. natural enemy predation; In the time meeting Storm Flood attack, even the unrestrained ridge of water, fish also can not be escaped, and only, otherwise dead because of anoxic, in cage, just energy normal growth of fish, guarantees output.

The utility model structure is simplified, and easily makes, and general peasant household all can make by oneself, and except the outsourcing of nylon outer net palpus, the material of remainder is expensive to plastics, iron wire, be inexpensive as to bamboo cane, batten and Teng bar etc. and all can use, thereby manufacturing cost is very cheap.
