Crayfish trapping agent and use method thereof

Abstract

The invention discloses a crayfish trapping agent and a use method thereof. The trapping agent is rapeseed oil residue, wherein the rapeseed oil residue is fresh rapeseed oil residue, and the preservation time is less than 24 hours. The method comprises the steps that the rapeseed oil residue trapping agent is contained in a silk bag, then the silk bag is hung on the inner top of a ground cage, the ground cage is flatly placed in a water area where crayfish needs to be fished, the crayfish distributed in the nearby water area can smell the taste of the trapping agent and gather into the groundcage, and then the cage is collected. The economic investment required by adopting the rapeseed oil residue trapping agent is low; the rapeseed oil residue is an edible organic matter which is easy to decompose, does not pollute a water body, can be eaten as a food source of part of organisms, and does not pollute the environment; the average trapping amount and the maximum trapping amount of therapeseed oil residues are superior to those of other trapping agents, the trapping effect is good, and a good using effect is achieved.

Description

technical field [0001] The invention relates to a crayfish trap, in particular to a crayfish trap and a using method thereof, which belong to the technical field of food. Background technique [0002] Since crayfish is an important aquatic economic animal in my country, it is very popular with people, so at present, domestic [0003] There are few reports on the prevention and control of Procambarus clarkii, and the only suggestion is to establish a specific protection zone before crayfish invasion. [0004] Ecological detection system to prevent crayfish from invading into ecologically sensitive areas, or increase fishing efforts in flooded areas [0005] And encourage the locals to eat it. However, many studies have shown that crayfish have a strong ability to accumulate heavy metals such as copper, cadmium, zinc, lead, mercury, and chromium, and frequent consumption of contaminated crayfish may cause rhabdomyolysis and acute renal failure in humans disease and other di...

[0006] Now the general salvage method still adopts the original salvage method. This salvage method needs to consume a lot of manpower and material resources, and crayfish have been living in caves for a long time. Blind salvage will only be futile.
