Description

Technical field:

[0002] The utility model belongs to the technical field of fishing, and in particular relates to a fishing tool, namely a simple folding scoop net, which is mainly used in the process of transferring mackerel fry in a round barrel container. Background technology:

[0004] Carp ( Opsariichthys bidens ) is also known as the horse-mouth fish, peach blossom fish, flower fork fish, and wide mouth. It belongs to the Cypriniformes, Cyprinidae, and horse-mouth fish genus. The horse-mouth fish has tender and delicious meat and high nutritional value. The intramuscular spines soften after cooking. The muscle contains 7 essential amino acids for the human body, of which the lysine content is as high as 7.04%, the crude protein content accounts for 18.78%, and the crude fat content is 1.79%. It is a high-protein, low-fat economic fish, known as the "best fish".

[0005] In recent years, artificial breeding of black carp has been carried out in Fujian, Zhejiang, Hunan, Hubei and other places, and commercial fish farming has been successfully carried out in ponds, reservoir cages, circulating water facilities and other models. It has become a new specialty freshwater fish farming variety. Black carp has the characteristics of short breeding cycle, strong disease resistance, strong reproductive capacity and fast growth rate, and is deeply welcomed by farmers.

[0006] The black carp is ferocious, fast and responsive by nature, which gives it an advantage in survival in the wild, and it can quickly capture prey and cope with various environmental challenges. Although it has been domesticated and artificially bred, the black carp still retains a certain wildness, and shows a certain degree of stress response during the fishing process of black carp fry, which increases the difficulty of fishing and the chance of fry being injured. With the rise of intensive seedling cultivation models, more and more black carp fry are cultivated in small water bodies in the early stage. This seedling cultivation model is conducive to the centralized feeding of artificial bait and improves the efficiency of seedling cultivation, but there are also problems such as difficulty in fry transfer. There are currently no reports on special black carp fry catching tools in barrels. It is particularly important to develop special fishing tools for black carp fry in barrel containers and study related fishing technologies in the development of the black carp industry.

[0007] A Chinese patent "A large-capacity fish fry open-mouth bait fishing tool" with publication number CN215380893U was retrieved. The tool comprises a buoyancy bag opening (1) and a net bag (2). The inlet end of the net bag (2) is connected to the buoyancy bag opening (1), and the tail end of the net bag (2) is a tapered closing structure. A counterweight (3) is installed at the lower end of the buoyancy bag opening (1) to make the buoyancy bag opening (1) perpendicular to the horizontal. The weight of the counterweight (3) should ensure that the upper part of the buoyancy bag opening (1) floats above the water surface. A traction rope (4) is also connected to the buoyancy bag opening (1). The patent has a simple structure, low cost and is easy to operate. However, it is inconvenient to use and has low efficiency when catching fish fry in a drum. Summary of the invention:
