Description

Technical Field

[0001] The utility model relates to the technical field of fish diversity investigation, in particular to a fish catching auxiliary device. Background Art

[0002] In recent years, biodiversity surveys and studies and water ecosystem health assessments have been widely carried out across the country, including surveys and studies on animals, plants, and aquatic organisms. Among them, fish diversity surveys are important groups and must-measure indicators for water ecosystem surveys and health assessments. When conducting fish biodiversity surveys in the entire river basin, most of the time, different types of river sections will be faced, such as wadable river sections, non-wadable river sections, reservoir river sections, and karst cave underground rivers. The survey tools are also different, generally including low-power electric fish machines, floating barb nets, floating barb nets, ground cage nets, rolling hooks, etc. Due to the implementation of fishing bans, the commonly used methods are floating barb nets and ground cage nets.

[0003] Since the existing major rivers and important lakes are basically in a state of fishing ban throughout the year, and fishing boats are cleaned up, converted, and landed, most of the existing waters have no fishing boats available for fish diversity fishing surveys, and it is also difficult to find available boats in most non-scenic areas, non-main navigation waterways, deep mountain canyon waterways, small river reservoirs and other waters. Therefore, during fish diversity fishing surveys, rafts are often used for fishing, which have the advantages of being easy to carry, flexible to use, and low cost. However, when laying and collecting fishing nets during fishing surveys, due to limited space, there is often little remaining space after two people take the boat, and there is basically no remaining space for the placement of fishing nets and tools such as nets and buckets. The operators are not able to place and collect fishing nets, and there are many impurities such as garbage and dead branches on the nets when collecting the nets in most waters, which makes the nets easy to knot and entangle, greatly prolonging the time for sorting the nets, or seriously affecting the next use, seriously affecting the fishing efficiency of the operators and the service life of the nets.

[0004] Most of the existing fish fishing auxiliary devices are used for concentrated fishing in aquaculture, or for large fishing vessels to use auxiliary devices during marine fishing. They are suitable for large-scale, large-scale, and large-scale fishing, but not for small-scale fish diversity surveys. Moreover, such devices are highly integrated with nets to form an integrated and complex device, which is inconvenient to carry and complicated to operate. It is not suitable for small kayak fish diversity surveys and cannot effectively solve the problems of slow kayak fishing efficiency and short net life. Utility Model Content

[0030] In this embodiment, two support rods 2 are respectively arranged on the port side 101 and the starboard side 102 of the kayak 1. The support rods 2 are used to fix the fishing nets to prevent the nets from being placed directly in the kayak 1, which would occupy the working space of the staff. An arc-shaped base 201 is provided at the lower end of the support rod 2 to fit the height of the edge of the kayak in the inflated state, thereby improving the stability during use. A first connecting rod 3 is provided between the two support rods 2 to improve the stability of the support rods 2 when connected. A separate first guide rail 301 is arranged along the length of the first connecting rod 3. A plurality of net hooks 302 are slidably provided in the first guide rail 301. The net hooks 302 are used to suspend the nets on the first connecting rod 3, which is convenient for the staff to lay out and collect the fishing nets. At the same time, a second connecting rod 5 is arranged at intervals below the first connecting rod 3.
