Abstract
The utility model discloses an artificial shrimp nest of freshwater shrimps, which is formed by combining a plurality of pieces of float-grass-shaped structural bodies, and is characterized in that: each float-grass-shaped structural body is made of deep-colored low-density polyethylene plastics (LDPE). Plastics are adopted to be made into the float-grass shape so as to provide a rest place for growth and daily life of the freshwater shrimps, to prevent freshwater shrimps from being killed by each other during the culture process and to effectively improve the culture yield of the freshwater shrimps. When the freshwater shrimps are caught, only a dip net is required to arrange below the artificial shrimp nest, then the artificial shrimp nest is shaken, and all freshwater shrimps on the shrimp nest can be caught in the net. The artificial shrimp nest is characterized in that: lightness and convenience in use can be realized, the service life is long, the artificial shrimp nest can be used for 6 to 8 years, and the artificial shrimp nest is free from polluting a water body during the application process.
Description
Technical field
The utility model relates to a kind of artificial shrimp nest of the instrument that supplies freshwater shrimp to perch and fish for freshwater shrimp, particularly a kind of freshwater shrimp.
Background technology
Freshwater shrimp (Macrobrachium nipponense), the formal name used at school Japanese macrobrachium supernbum is the important economic freshwater shrimps of China.It is nutritious, fine and tender taste, delicious flavour, and its culture-cycle is short, input cost is low, and the economic worth advantages of higher receives liking of consumers in general and raiser deeply.At present, the mode of fishing for of the freshwater shrimp of breed and wild freshwater shrimp have only ground cage net, dip net and draw in the net three kinds fish for mode.
Ground cage net is fished for freshwater shrimp, when temperature is high, fishes for freshwater shrimp, because temperature is high, the freshwater shrimp mobility is strong, and the inside freshwater shrimp density is high slightly shine easily into freshwater shrimp death to a certain degree when cage, causes damage to the fisherman; Simultaneously,,, also shine into damaging easily slightly the shelling of the inside the time at cage, influence economic benefit when freshwater shrimp in freshwater shrimp vegetative period.Draw in the net, just be fit to winter, temperature is lower, when the freshwater shrimp mobility reduces, is used for fishing for freshwater shrimp.Therefore, in conjunction with the method for artificial shrimp nest and diddle-net, then be a kind of very important mode that freshwater shrimp is fished for.
At present, the artificial shrimp nest that numerous raisers and fisherman use generally all is to become with materials processings such as tea tree branch or water peanuts.Their service life is short, the general maximum usefulness of making of the tea tree branch of artificial shrimp nest 2 years, and the artificial shrimp nest that water peanut is made then can only use at most a season.And the artificial shrimp nest made of tea tree branch or water peanut polluted water easily in the process of rotting, influence the growth of freshwater shrimp.
Summary of the invention
The utility model purpose is to solve the present artificial shrimp nest polluted water that rots, and service life short problem, to the raiser a kind of long service life, the artificial shrimp nest of cleaning easily are provided.
Realize the utility model purpose main technical schemes:
The artificial shrimp nest of a kind of freshwater shrimp has multi-disc pasture and water shape structure to combine, and it is characterized in that: said pasture and water shape structure material is dark LDPE.
Preferably: said artificial shrimp nest is high 60cm, the shape of the similar cone of base diameter 70cm.
Advantage of the utility model and effect:
The utility model utilizes plastics to process the shape of pasture and water, the habitat is provided for growth and the daily life of freshwater shrimp, avoids in the breeding process freshwater shrimp to kill each other, and effectively raises shrimp culture output.Only need when fishing for freshwater shrimp with diddle-net be placed on artificial shrimp nest below, then artificial shrimp nest is trembled, freshwater shrimp just all networks on the shrimp nest.Be characterized in using light, the life-span is long, can use 6～8 years, and can pollution not arranged to water body in the use.
Description of drawings
Fig. 1 is a monolithic pasture and water shape structure sketch map;
Fig. 2 is a multi-disc pasture and water shape structure combination sketch map.
Embodiment
According to behaviouristics and the life habit of freshwater shrimp, the model of pasture and water made of plastic, and with certain shape assembling more together, form a maneuverable artificial shrimp nest.
The utility model making step is following:
(1) selects material: preferably select brand-new, dark LDPE (low density polyethylene (LDPE)) for use, use and reclaim then possible toxic substances of raw material or penetrating odor, influence perching of freshwater shrimp.
(2) make monolithic pasture and water shape plastic patterns (like Fig. 1)
(3) assembling: with the rough and initial material model of the single piece of water of making, be fixedly assembled, form a fixing artificial shrimp nest.
(4) integer, typing: adjust artificial shrimp nest size, highly, make it be fixed as high 60cm, the shape of the similar cone of base diameter 70cm (like Fig. 2), handled easily.
Further the effect of the utility model is elaborated through instantiation below.
Instance 1:
3 mu of pond areas (long 70 meters wide 28 meters), mid-October, 20～25 ℃ of water temperatures are placed the artificial shrimp nest of 3 rows in the pond, and 10 of every rows after one week of placement, fish for diddle-net, catch 35 kilograms of freshwater shrimps altogether, and on average each shrimp nest can be fished for 1.16 kilograms of freshwater shrimps.
Instance 2:
3 mu of pond areas (long 100 meters wide 20 meters), at the beginning of 12 months, 8～12 ℃ of water temperatures are placed the artificial shrimp nest of 2 rows in the pond, and 15 of every rows after placement fortnight, fish for diddle-net, catch 45 kilograms of freshwater shrimps altogether, and on average each shrimp nest is fished for 1.5 kilograms of freshwater shrimps.
Instance 3:
5 mu of pond areas (long 100 meters wide 33 meters), at the beginning of 12 months, 8～12 ℃ of water temperatures are placed the artificial shrimp nest of 3 rows in the pond, and 15 of every rows after placement fortnight, fish for diddle-net, catch 75 kilograms of freshwater shrimps altogether, and on average each shrimp nest is fished for 1.67 kilograms of freshwater shrimps.
Claims (2)
1. the artificial shrimp nest of a freshwater shrimp has multi-disc pasture and water shape structure to combine, and it is characterized in that: said pasture and water shape structure material is dark LDPE.
2. the artificial shrimp nest of a kind of freshwater shrimp according to claim 1, it is characterized in that: said artificial shrimp nest is high 60cm, the shape of the similar cone of base diameter 70cm.
