Abstract
The utility model provides a large capacity fry initial feed fishing tool, characterized by: the buoyancy bag comprises a buoyancy bag opening (1) and a net bag (2), wherein the inlet end of the net bag (2) is connected with the buoyancy bag opening (1), and the tail end of the net bag (2) is of a gradually-reduced closing structure; the lower end of the buoyancy bag opening (1) is provided with a counterweight (3) which enables the buoyancy bag opening (1) to be vertical to the horizontal, and the weight of the counterweight (3) ensures that the upper part of the buoyancy bag opening (1) floats on the water surface; the buoyancy bag opening (1) is also connected with a hauling rope (4). The utility model has simple structure, low cost and easy operation.
Description
Technical Field
The utility model relates to an aquatic product technology, in particular to an auxiliary tool used in aquaculture, and specifically relates to a large-capacity fry initial feed catching tool.
Background
At present, in an aquatic breeding field or a fish research base, biological baits (rotifers, cladocerans, copepods and other zooplankton) are required to be used as initial baits to cultivate fish fries in each seedling growing season every year so as to meet the growth and development requirements of the fish fries, the demand is large under the common condition, and a special bait cultivating pond is arranged in a plurality of fish breeding fields. When the fry needs initial baits, the fry is directly fished out by a tuck net in the pond, but the use of the common tuck net consumes time and labor and has low efficiency due to large demand. Therefore, it is very important to design a fishing tool with large fishing amount and convenient operation.
SUMMERY OF THE UTILITY MODEL
The utility model aims to design a large-capacity initial bait catching tool for large-scale quick catching of fish fries, aiming at the problems of time and labor consumption and low efficiency of the existing initial bait catching of the fish fries.
The technical scheme of the utility model is as follows:
the utility model provides a large capacity fry initial feed fishing tool, characterized by: the buoyancy bag comprises a buoyancy bag opening 1 and a net bag 2, wherein the inlet end of the net bag 2 is connected with the buoyancy bag opening 1, and the tail end of the net bag 2 is of a gradually-reduced closing structure; the lower end of the buoyancy bag opening 1 is provided with a counterweight 3 which enables the buoyancy bag opening 1 to be vertical to the horizontal, and the weight of the counterweight 3 ensures that the upper part of the buoyancy bag opening 1 floats on the water surface; the buoyancy bag opening 1 is also connected with a traction rope 4.
The buoyancy bag opening 1 is of a square structure.
The buoyancy bag opening 1 is a hollow plastic pipe structural member.
The weight part 3 is a metal block or a metal pipe fitting.
The weight piece 3 is an aluminum alloy pipe or a galvanized pipe.
The utility model has the beneficial effects that:
the utility model adopts the dragging type fishing, and has the advantages of labor saving and convenience.
The utility model can catch a big bag of biological bait at one time and has the advantages of large quantity and convenience.
The utility model has the advantages of simple structure, low cost and easy operation.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The utility model is further described below with reference to the figures and examples.
As shown in fig. 1.
A large-capacity fry initial bait catching tool comprises a buoyancy bag opening 1 and a net bag 2, wherein the density of the net bag 2 is as small as possible on the premise of ensuring water permeability so as to ensure that caught biological baits cannot leak out of meshes, the inlet end of the net bag 2 is connected with the buoyancy bag opening 1, and the tail end of the net bag 2 is in a gradually-reduced closing structure; the lower end of the buoyancy bag opening 1 is provided with a counterweight 3 which enables the buoyancy bag opening 1 to be vertical to the horizontal, and the weight of the counterweight 3 ensures that the upper part of the buoyancy bag opening 1 floats on the water surface; two or four hauling ropes 4 are also connected to the buoyancy bag opening 1, and the hauling ropes can be nylon ropes. In specific implementation, the buoyancy bag opening 1 is preferably in a rectangular or square structure as shown in fig. 1, and can be made of hollow plastic pipes, the joint is sealed by sealant during manufacturing, and the joint can be connected by threads. In addition, the weight member 3 may be a metal block or a metal pipe member, and is generally commonly an aluminum alloy pipe or a galvanized pipe.
When the bait culture device is used, the traction rope 4 is grabbed, then the whole fishing tool is thrown into the bait culture pond, the traction rope is pulled by hand to move forwards along the dike, and the net bag is filled with bait, so that the buoyancy bag opening can be lifted up and taken out of the water surface.
The parts not involved in the present invention are the same as or can be implemented using the prior art.
Claims (5)
