Cage for catching lobster at ocean floor

Abstract

The invention discloses a capture cage for lobsters on the seabed, which consists of a fish net, a cage body, smell luring boxes, a lobster inlet, a pedal and an inclined sliding plate. The fish net is arranged on the periphery of the cage body; the smell luring boxes are arranged in the cage body; the peripheral wall of the cage body is provided with the lobster inlet; the sliding plate is positioned on the outer side of the lobster inlet; one end of the pedal is connected with the side wall of the cage body through a hinge, while the other end of the pedal is contacted with the undersea surface; the inclined-inward sliding plate is positioned on the inner side of the lobster inlet; the middle parts of cross beams on two sides of the cage body are provided with folding connectors which can make the cross beams on the two sides fold inward; the cage body is divided into an upper cage and a lower cage to strengthen the function of the cage body of preventing the lobsters from escaping;a plurality of the smell luring boxes are vertically arranged so as to reduce water resistance of the smell luring boxes, avoid the horizontal or insequent sliding of the cage body, and ensure that the cage body can accurately reach the target seabed; the cage body adopts a foldable structure, thereby greatly facilitating the carrying and transportation of a fishing boat; and the smell luring boxes are arranged on two sides of each inlet so as to greatly strengthen the trapping function.

Description

technical field [0001] The invention relates to a lobster trap, in particular to a sea lobster trap with a folding function for a cage body for fishing lobsters on the seabed. Background technique [0002] At present, the lobster traps used by fishermen at home and abroad are basically half-moon-shaped. The cage body does not have a folding function, and its volume is large, which is not convenient for fishing boats to transport. One entrance is not convenient for multiple lobsters to enter at the same time, and the catch is limited. In order to prevent the lobster from entering the cage from escaping, the size of the circular entrance is set very thin, because there are two long spines in front of the lobster, and the spines of the lobster are easy to be fenced out of the cage if the entrance is thin, which increases the difficulty for the lobster to enter the cage , it can be seen that this structure has a great limit on the catch, because the entrance of the cage is set...

Problems solved by technology

[0002]At present, the lobster traps used by fishermen at home and abroad are basically half-moon-shaped, and the cage body does not have the function of folding. The carrying capacity of the trap is greatly limited; the traditional trap has only one entrance, which is not convenient for multiple lobsters to enter at the same time, and the catch is limited

In order to prevent the lobster from entering the cage from escaping, the size of the circular entrance is set very thin, because there are two long spines in front of the lobster, and the spines of the lobster are easy to be fenced out of the cage if the entrance is thin, which increases the difficulty for the lobster to enter the cage , it can be seen that this structure has a great limit on the catch, because the entrance of the cage is set on the side of the cage and is not high from the seabed. According to the characteristics of the lobster: when the lobster finds that it is trapped, the lobster will walk around to find the exit , when the exit is found, it will try to flee, which shows that the anti-flight function is not ideal
