Abstract
The utility model relates to a fry protective device. When a fishing work is processed, the fry protective device 5 is tightly tied to the end opening of the net bag of a trapping net 3 and a steel rope of the net opening is colligated to a plurality of bamboo poles 1. The fishes pass through a fish ring 4 following the running water and finally get to the fry protective device. A part of young fish fries can successfully pass through a plurality of small holes on the fry protective device and swim back again to the sea, the river or the lake. But the fishes with bigger bodies are caught in the fry protective device. The big fishes are caught and the young fishes are freed, so the goal of protecting the fishery resource is reached. The utility model is an important supplementing means for performing the fishing off season.
Description
The utility model relates to a kind of Fry protective device, belongs to the technical field that protects fishery resourses.
Before this, with (a kind of title of the fishnet) fishing of throwing the net, the network interface of throwing the net is opened very greatly, afterbody dwindles gradually, become bag shape, mesh is a maximum with the network interface place also, dwindles gradually to the bag end inwards, under the pulling function of flowing water, whole throwing the net is elongated, and bag bottom mesh closes tightly, so enter the fish in the net, large or small, all do not escape the destiny of being annihilated.
The objective of the invention is to utilize Fry protective device, making into, the people throws the net---and also be the fish in the Fry protective device, wherein the individual very little fry of a part can return to sea or river, river, lake by the aperture on the protector, and continued growth is grown.
In order to achieve the above object, the following technical measures of special employing: Fry protective device is made with materials such as plastics or metallic plates, and shape has a lot of apertures as a vase that young belly is big on the wall, and the size in hole can be smoothly by being standard with fry.The bottom of Fry protective device does not have the hole.The mesh bag of throwing the net does not have the end yet, and Fry protective device just ties up to the nethermost openend of mesh bag tightly.
Economic benefit can't estimate.In a word, swim back fry in sea or river, river, the lake again by the aperture on the Fry protective device, through growing of some months or several years, individuality will increase several times, tens times and even hundred times, and economic benefit also will correspondingly increase.
Accompanying drawing 1 is the fishing flow diagram of throwing the net, and wherein 1 is bamboo pole, the 3rd, throw the net, and the 5th, Fry protective device, the 4th, fish blocking ring, the 2nd, anchor.Fish blocking ring is woven into rectangular elastomeric material, and free end tilts in protector, stops fish to be escaped from from the Fry protective device mouth.
During the netting operation; Fry protective device 5 is tied up to the nethermost openend of the mesh bag of throwing the net together with fish blocking ring 4; the guiding principle rope of network interface then colligation on several bamboo poles 1; anchor 2 is suspended on the bamboo pole; under the effect of flowing water; throw the net and extend; and more near the end opening of netting; mesh closes more tightly; fish in the water enters in the net with flowing water, arrives in the Fry protective device, because of flowing water speed in the Fry protective device slows down by fish blocking ring at last; so wherein partly individual very little fry is able to swim go back to sea or river again by the aperture on the wall; the river; in the lake, individual big fish then is trapped within the Fry protective device.
