Abstract

The utility model discloses a high efficiency fluorescent fish cage, relating to a fishing tool of aquatic products, which is arranged in water areas of a river, a lake or a sea for luring fish, shrimps and crabs. The utility model is composed of a cage frame and a cage net. The cage frame is in a column shape, and is made of a wire, and can also be folding or extended in axial direction. An end part is fixed with a circular arc-shaped permanent magnetism strip. The cage net is woven by a screen wire, and is surrounded at the periphery of the cage frame. An end or a side is provided with a cone network interface for extending in the cage, and a fluorescent floating ball which can send out fluorescence is tied in the cage. The utility model skillfully uses the phototaxis and magnetotactic performance of the animals, such as fish, shrimps and crabs, and thus the efficiency of trapping aquatic products can be visibly enhanced without frequently changing baits.

Description

The high-efficiency fluorescence fish pot

The utility model relates to a kind of fishing device that is used to trap fish shrimp crab class aquatic products in the waters such as rivers,lakes and seas that is placed in.

Fish pot is a kind of fishing device commonly used, when placing bait and fish pot being placed in waters such as rivers,lakes and seas in fish pot, can trap aquatic products such as fish shrimp crab.Though the pattern of fish pot is varied, basic structure is identical, mainly is made of cage frame and cage net.The fish pot that is most widely used, its cage frame is cylindrical, makes and can axially press folded or stretching, extension by metal wire.The cage net then is made into by netting twine, is enclosed in the periphery of cage frame, and the network interface that enters fish pot for fish is left in end or side.In order to prevent that the fish that enter fish pot from escaping from fish pot, network interface is answered tapered and is stretched in the cage.Fish pot of the prior art is simple in structure, it axially can be pressed when transporting or depositing and fold, to reduce its volume; During use, again it is trailed.The outstanding defective of fish pot of the prior art is that the bait mode is single, almost completely relies on the bait that is positioned in the cage and traps fish, and not only catching rate is very low, and must frequently change bait.

The purpose of this utility model promptly is the fish pot structure is improved, and a kind of high-efficiency fluorescence fish pot is provided, to improve the efficient of trapping fish shrimp crab class aquatic products.

To achieve these goals, the utility model utilizes become light characteristic and the magnetotactic characteristic of fish shrimp crab class animal, but bolt is the fluorescence ball float that a plurality of entire bodies are sent fluorescence in fish pot, installs and fixes the permanent magnetic strip of a plurality of circular arcs in the end of fish pot.So the fluorescence fish pot that constitutes is not only traped efficient and is obviously improved than single bait fish pot, and needn't frequently change fluorescence ball float and permanent magnetic strip, thereby uses more convenient.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model high-efficiency fluorescence fish pot.

Accompanying drawing 1 is the structural representation of the utility model high-efficiency fluorescence fish pot.

With reference to the accompanying drawings 1, the utility model high-efficiency fluorescence fish pot mainly is made of cage frame, cage net, fluorescence ball float and permanent magnetic strip.Cage frame 1 is cylindrical, makes and can axially press folded or stretching, extension by wire.Cage net 2 is made into by netting twine, is enclosed in the periphery of cage frame 1, and the taper network interface 3 that stretches in the cage is left in its end or side.But fluorescence ball float 4 is made and the entire body emitting fluorescence by fluorescent material, ties up in the cage by the netting twine bolt.Permanent magnetic strip 5 is a circular arc, is fixed on the end of cage frame 1.

The utility model has been owing to utilized the light magnetotactic characteristic that becomes of fish shrimp crab class animal dexterously, thereby can significantly improve trapping efficient, and fluorescence ball float and permanent magnetic strip needn't frequently be changed, thereby use more convenient.Glimmering ball float and permanent magnetic strip can make respectively also that fishing is floated and plumbous stone roller is used for fishing gears such as linked network, set net and trawlnet except that being specially adapted to fish pot.

Claims

1. one kind is placed in the high-efficiency fluorescence fish pot that is used to trap aquatic products such as fish shrimp crab in the waters such as rivers,lakes and seas, is made of cage frame and cage net; The cage frame is cylindrical, makes and can press vertically folded or stretching, extension by wire; The cage net is made into by netting twine, is enclosed in the periphery of cage frame, and the taper network interface that stretches in the cage is left in end or side; Feature of the present utility model is that but bolt system has entire body to send the fluorescence ball float of fluorescence in the cage, and the end of cage frame is mounted with the permanent magnetic strip of circular arc.
