Abstract
The utility model discloses a landing-spoon with water. The landing-spoon with water is an aquaculture net. The landing-spoon with water is characterized in that an ordinary landing-spoon with an open bottom is combined with an ordinary plastic ladle head, and the landing-spoon with water is the combination of the landing-spoon and a ladle. The utility model solves the problem that the ordinary landing-spoon can cause frail moving hydrobiont to die when fishing and the problem that Roe pond crayfish moving with ova can have abortion since the ova are separated when the landing-spoon is used for fishing. The landing-spoon with water has simple structure and easy use.
Description
The invention discloses a kind of Landing-spoon with water, is a kind of aquaculture netting gear.
Some aquatic livestock, for example Crimson sea bream fish can not dried uply move, and a leaving water will cause mortality.Macrobrachium rosenbergii is the improved seeds of freshwater aquiculture, and in the artificial propagation of Macrobrachium rosenbergii, the certain hour after laying eggs is joined in the mixed flock-mate of male and female, will move on to the hatchery to the female shrimp of oogenesis, hatches and grows seedlings.Because when fishing for, shrimp with ovums one leaving water will acutely bounce, and causes the ovum abscission, so in clear and definite regulation on the textbook: " before hatching, avoid waiting and fish for or move it with net, if will fish for, catching up with in the bucket, Lian Shui be taken as together should ".But in the shrimp pond, move shrimp with ovums with the method for " catch up with in the bucket, Lian Shui gets together ", need in people's shrimp pond, both time-consuming, effort again, also easy other close shrimp of injury.
Above-mentioned Crimson sea bream fish is fished for dried up death and the Macrobrachium rosenbergii shrimp with ovums is fished for the dried up many disadvantages that cause miscarriage in order to overcome, and providing a kind of can fish for flexibly, again can not must dried up realization move conveniently drag for tool, just become crucial technical task.
The purpose of this invention is to provide a kind of Crimson sea bream fish that makes and in fishing for, avoid dried up causing death, the Macrobrachium rosenbergii of oogenesis is fished for avoid when mobile the dried up spring miscarriage that causes, both time saving and energy saving, operate nimble Landing-spoon with water again.
The present invention finishes like this: it includes and constitutes handle, iron ring and the dredger body that tradition is dragged for son, and its technical essential is: be installed with a bucket in the bottom of dredger body.This bucket can be a truncated cone-shaped, also can be other shapes.Its bucket is preferably made with material transparent, and is both non-friable as water white plastics or lucite, is convenient to again from visual observation shrimp ovum quantity and growth color.Its base diameter should with shrimp with ovums length quite or bigger, the degree of depth be the shrimp body thick more than three times, back cut diameter has tapering slightly greater than end diameter.And suitable for reading all along many apertures are arranged, so that stitched together with dredger body 2.Dredger body 2 adopts the net sheet of about 1 centimetre of mesh to make for shrimp with ovums, for Crimson sea bream fish, then uses the soft screen cloth about 60 orders instead.The color of net sheet generally adopts pale green or pale blue, is advisable with the vision that does not stimulate fishes and shrimps.The end opening of dredger body 2 is sewn on the bucket 1, suitable for reading being sewn on the iron ring 3.Said dredger body 2 suitable for reading greater than end opening forms certain taper, and its length is about 25 centimetres.The effect of iron ring 3 is that network interface is strutted, and firmly is connected with handle 4 simultaneously.The material of iron ring 3 is selected for use usually and is given the stress twine, and intensity is in light weight greatly, and its bore is about 25 centimetres.Handle 4 is selected thickness suitable bamboo bar or waddy for use, and length is generally about 1.5 meters, or determines according to the specification of shrimp-cultivation pool.
When the present invention uses, only need grasp handle outside the pond as using the common son that drags for, just can drag for shrimp with ovums in the bucket 1 of institute's tax, realize not dried up fishing for and mobile.Advantage of the present invention is a simple structure, and is easy to use, solved not dried up a great problem of fishing for the Macrobrachium rosenbergii that moves fragile fry and oogenesis.
Figure of description is an organigram of the present invention.Among the figure: 1---bucket, 2---the dredger body, 3---iron ring, 4---handle.In an embodiment of the present invention, said Landing-spoon with water is actually a common son bottom of dragging for is opened, and joining with the head of a plastics dipper forms.Plastics baler head is said bucket 1, and bore is 15 centimetres, and end diameter is 12 centimetres, dark 7 centimetres, and light green.The mesh of said dredger body 2 is 1 centimetre a green etting.Dredger body length is 25 centimetres.No. 8 iron wires of said iron ring 3 usefulness are made 25 centimetres of diameters.Said handle 4 adopts the bamboo bar, and length is 1.5 meters.Be used for fishing for the Macrobrachium rosenbergii light and flexible of mobile oogenesis, shrimp with ovums is in the water of bucket 1, and is quiet and do not bounce, and do not cause substantially and takes off the ovular abortion phenomenon, and result of use is fine.
