Description

A kind of Macrobrachium rosenbergii fishes for sampling instrument

Technical field

The utility model belongs to fishery fishing tool technical field, and in particular to a kind of Macrobrachium rosenbergii fishes for sampling instrument.

Background technology

Macrobrachium rosenbergii also known as Malaysian prawn, the long-armed prawn of fresh water, are a kind of large-scale fresh water shrimps, originate in Southeast Asia. It has that growth is fast, feeding habits are wide, meat nutrition composition is good, and the culture-cycle it is short the advantages of.The people since the 1960's Since work cultivation Macrobrachium rosenbergii, quickly grow, existing country in Southeast Asia and some other area cultivation Macrobrachium rosenbergii are commonplace.I State introduced this shrimp from 1976, in Guangdong, Guangxi, Hunan, Hubei, Jiangsu, Shanghai, Zhejiang Deng Shiduoge provinces, cities and autonomous regions Cultivated, general per mu yield achieves obvious economic benefit up to 300~600 kilograms.

Need to carry out repeatedly fishing for sampling during Macrobrachium rosenbergii is cultivated, the purpose for fishing for sampling is to grasp sieve Situations such as growth of family name pond crayfish occurs with disease, in favor of aquaculture management.Existing Macrobrachium rosenbergii fishes for sampling instrument to push net, As shown in figure 1, front end of pushing net is network interface, the network interface beam 5 and two head ropes 4 that network interface is done by bamboo plate are constituted, and are bored in the middle of network interface beam 5 Hole iron wire is connected with mao bamboon handle 6, " T " shape structure, and net is flexible nylon wire according to 2, and mesh is 10 mesh, and net is in pocket according to 2 Shape, is fixed on "T"-shaped framework with gang rope.It is off line from waterside during using pushing net, it is quick to implementation, Roche at deep water with manpower Pond crayfish because escape not as good as fall into be caught in the string bag pushed net and reap.Macrobrachium rosenbergii is creeped or adhered at the bottom On pasture and water, meeting " bend over and wag the tail " is escaped rapidly to profundal zone after getting a fright.The technological deficiency of the presence of pushing net of prior art It is：In actual application, because the direction of advance pushed net is identical with the escape direction of shrimp, so shrimp is difficult network access；In water When in the more pond of grass using pushing net, due to the obstruction of pasture and water, movement velocity of pushing net is slow, it is difficult to capture Macrobrachium rosenbergii.

Utility model content

For above-mentioned problems of the prior art, the purpose of this utility model is that providing one kind can avoid the occurrence of The Macrobrachium rosenbergii for stating technological deficiency fishes for sampling instrument.

In order to realize above-mentioned utility model purpose, the technical scheme that the utility model is provided is as follows：

A kind of Macrobrachium rosenbergii fishes for sampling instrument, including base ring 1, choma 3, network interface beam 5 and handle 6, base ring 1 and choma 3 For identical arc, the two ends of base ring 1, the two ends of choma 3 are respectively fixed on the two ends of network interface beam 5, and one end of handle 6 is fixed On the midpoint of base ring 1, the midpoint of choma 3 is fixed on handle 6, tight covered with spacer screen, bottom between base ring 1 and network interface beam 5 It is tight covered with cover net between ring 1 and choma 3.

Further, the angle of cover net and spacer screen is 60 °.

Further, cover net and spacer screen are polyethylene knotless net.

Further, the camber of base ring 1 and choma 3 is 45cm.

Further, the length of network interface beam 5 is 65cm.

Further, the air line distance between the midpoint of base ring 1 and the midpoint of choma 3 is 45cm.

Further, handle 6 and spacer screen are into 60 ° of angles.

Further, the other end cuff rubber sleeve 7 of handle 6.

Further, the other end of handle 6 is fixed with the Anti-rope drop 8 that a root system ring buckle.

The Macrobrachium rosenbergii that the utility model is provided fishes for sampling instrument, changes traditional fishing style, is changed to by pushing out Inwardly take off, the direction of inside crab dredge and the escape of shrimp are in opposite direction, blocked shrimp to the route of retreat of escape at deep water, inside crab dredge Speed is slower, more adapts to the motion mode that shrimp slowly creeps, network interface beam can depress pasture and water, so that the obstruction of pasture and water is avoided, it is attached The shrimp on pasture and water to be easy to by from getting rid of on pasture and water and being then grilled into net, it is high with capture rate, it is easy to use, by ring The advantages of border condition limitation is few, the need for practical application can be met well.
