Description
Technical Field
The utility model relates to the field of growth of procambarus clarkii, in particular to a device for detecting the growth condition of Cha Keshi procambarus clarkii.
Background
The current method for mainly capturing procambarus clarkia can be divided into six types. Firstly, the most common ground cage catching method is that a farmer puts feed or bait in a fixed ground cage, and crayfish cannot come out once eating from an opening. The ground cage has the size of a minute, the ground cage has high capturing efficiency, repeated folding every day is not needed, but the labor intensity is high; the small ground cages need to be repeatedly stowed each day. The second is bamboo cage method, which uses bamboo or metal wire to weave into a cylindrical cage with 10cm diameter, the opening has barbs to prevent escaping, and the catching principle is similar to that of ground cage. Due to the limited space within the cage, it is often necessary to arrange multiple cages for use. The third is trawl fishing method, which requires a great deal of manpower cooperation, and the principle is the same as trawl fishing, so that crayfish can be caught at one time. The fourth is to use a hand net to directly capture the fish in the aquatic plant or artificial shrimp nest area. The fifth method is a shrimp ball method, which is to put the shrimp balls into water, put some soft materials inside, and catch the crayfish by utilizing the light-proof hole hiding habit of the crayfish. The sixth is a hanging wire method, which is commonly used for recreation, to tie the liver or meat on the wire to fish the shrimp. In the six fishing methods, besides the hanging line method, the crayfish is convenient to observe, and other methods and devices are not suitable for observing the crayfish. Although the hanging wire method is convenient, the feeding condition of the crayfish cannot be observed specifically.
It can be seen that the existing method for catching crayfish lacks intermediate-level catching means and observing devices. Such as a ground cage, a hand net and a trawl net, the efficiency of catching shrimps is high, the high efficiency brings high labor intensity and high manpower, and the catching means basically need cooperation between two people and even teams. The small ground cage, the bamboo cage method, the shrimp ball method and the hanging wire method are limited by the volume of the fishing gear, the catching amount at one time is small, and in order to solve the problem, the volume is increased and the labor cost is increased, or a large number of bamboo cages, shrimp balls are purchased and the material resources and the maintenance cost are increased.

As shown in figures 1 and 2, the device for detecting the growth condition of Cha Keshi procambarus clarkii comprises a floating platform (2), ropes (3), an upper outline (4), a lower outline (6), a bottom screen cloth (7), side canvas (5) and hooks (1), wherein the hooks (1) can hook the whole device, the floating platform (2) provides buoyancy so as to prevent the ropes from falling down, the ropes (3) connect the floating platform (2) with the bottom, the upper outline (4) and the lower outline (6) are of a circular ring structure, the diameter of the upper outline (4) is larger than that of the lower outline (6), the upper edge of the side canvas (5) is wrapped on the upper outline (4), the lower edge of the side canvas (5) is wrapped on the lower outline (6), the bottom outline (7) is arranged on a circular plane where the lower outline (6) is located, and the upper outline (4), the lower outline (6), the side canvas (5) and the bottom canvas (7) form a bowl shape. A plurality of sinkers (8) are arranged on the lower line (6). The side canvas (5) adopts canvas to avoid crayfish from escaping.
The buoyancy of the floating platform (2) is larger than the gravity of the rope (3). The length of the rope (3) depends on the water depth of the pond and the diameter of the upper line (4), and if the diameter of the upper line (4) is 112cm and the water depth is 50cm, the length of the rope (3) is more than 75cm, and 80cm can be selected.
The diameter of the upper line (4) depends on the diameter of the lower line (6), and the ratio of the diameter of the upper line (4) to the diameter of the lower line (6) is 112:100, i.e. the diameter of the lower line (6) is 100cm, the diameter of the upper line (4) should be 124cm, and the ratio can be such that the vertical height of the upper and lower lines is about 20cm, which is much higher than the height of the crayfish.
The diameter of the lower line (6) can be adjusted, and if the fishing amount is required to be increased, the diameter of the lower line (6) can be increased. The diameter of the lower line (6) is 100cm, the bottom mesh (7) is a mesh with a mesh size of about 2cm, and the sinker (8) is assembled on the lower line (6) so that the lower line (6) can be sunk on the bottom mud.
Taking animal feed with good palatability as an example, after the device is placed for two hours, the device is lifted, and the animal feed is basically consumed, so that the feeding condition of the crayfish is good. If the residual feed is excessive, attention is paid to the health condition or water quality of the crayfish.

Comparison of fishing examples:
a, floor cage: generally, 1-2 ground cages are placed in each mu of water area, and the size of the ground cages is determined. The cage collecting speed is adjusted according to the actual situation, and if the cage collecting speed is slow and the cage feeding speed is fast, the crayfish can die due to lack of oxygen. The ground cages are collected and sun-dried every ten days.
b bamboo cage shrimp ball: 10-25 bamboo cages are placed in each mu of water area, and the number of shrimp balls can be reduced. The crayfish can be caught for about 70% after 3-4 days of continuous catching.
And c, drawing a net: it is necessary to clear the obstacles in the water in advance and sweep the pre-capture sites with a net. The one-time catching rate is high, and the device needs to be matched by multiple people.
And d, by adopting the method for catching crayfish, 6-8 devices are needed in each mu of water area. After the device is put down, the crayfish can be taken in about 1 hour, and can be operated by one person back and forth within one day without worrying about hypoxia of the crayfish. The device is convenient to collect, the catching rate is high, and the catching times are relatively less.
