Description
Technical Field
The invention belongs to the technical field of aquatic product fishing, and particularly relates to a novel crab pot.
Background
Since ancient times, crabs are very delicious foods, and eating crabs as a cultural enjoyment caused by leisure and promotion starts from the Wei and jin period, so that the crabs are popular with people. The crab is rich in protein and trace elements, and has good nourishing effect.
Most species of crabs live in the sea or offshore areas, and some also live on fresh water or land. Crabs are high in flexibility and difficult to catch by hands, and are generally caught by adopting a catching cage. And putting baits into the catching cage, putting the baits into water, and catching the cage for collecting the crabs after the crabs are put into the cage.
As crabs are different from general fishes and need firmer and rigid catching tools, the traditional crab pot is characterized in that the nets on the side surfaces of a circular three-dimensional frame form attraction ports respectively, baits are placed in the middle of the pot, and the crabs enter the pot through the attraction ports. In addition, in order to lure the crabs into a large individual, the conventional lure mouth is generally large in diameter. However, conventional crab pots: 1) the crabs entering the cage are squeezed in the same space, so that the probability of mutual competition and attack is increased, and the individual crabs are easily injured; 2) crabs are easy to be entangled when entering the luring port, so that the entrance is blocked, and other individuals are influenced to enter; 3) the diameter of the luring mouth is very large, so that the juvenile crabs are difficult to be caught at the same time.
Disclosure of Invention
The invention aims to provide a novel crab pot which has high catching efficiency, prevents the blockage of the crab pot inlet, has a plurality of crab catching spaces, avoids young crabs escaping, has strong stability in water, and can prevent any microorganism and algae from being adhered to a net.
The scheme adopted by the invention for realizing the purpose is as follows: the utility model provides a novel crab pot, is including the box net frame that is connected with the netting, and the base is connected to the netting bottom, and the superficial post is connected at the base middle part, and the whole length of superficial post is less than the height of box with a net, and the outer lane of superficial post encircles and has laid the frame, and the frame surface is connected with and keeps off the net, and the frame separates into a plurality ofly with the space of box with a net inside, and the box with a net puts up the outside and is equipped with tightly and closes the mechanism. The crab pot can not be folded in aqueous, the steadiness is better, the superficial post at base middle part can play the save effect to bait, avoid bait diffusion velocity in aqueous too fast, the superficial post height is slightly less than the box with a net height, inside the box with a net is all fallen into to the bait that enables oozing in aqueous, the frame on superficial post separates into a plurality of spaces with the box with a net inside, the crab of avoiding catching concentrates on the mutual competition that arouses the crab class together, reduce raiser's income, locate the tight mechanism that closes in the box with a net frame outside and can effectually prevent that the crab class from climbing out from the box with a net once more, efficiency is catched in the improvement.
