Description

Technical Field

[0001] The present invention relates to the technical field of river fish resource investigation, and particularly relates to an intelligent fishing-type river fish resource investigation device and method. Background Art

[0002] The existing river fish resource investigation mainly adopts the artificial on-site investigation method. The specific method is as follows: In a temporarily selected shallow water area of a wild river channel, through artificial means such as setting fishing nets or placing fish traps, after the fish catches are fished ashore, the types and quantities of fish resources are manually counted.

[0003] The traditional artificial on-site investigation method for fish resources has the following problems:

[0004] (1) The investigation time of on-site personnel is discontinuous. Fish resource investigations are often carried out only on specific days, which is accidental. Due to reasons such as water temperature and flow changes, the amount of fish resources captured in the same period of different years cannot fully represent the current fish situation in this river section. Continuous fixed-point fish resource investigations need to be carried out. However, relying solely on the artificial timing observation method has the problems of high cost and low efficiency, and there is an urgent need to carry out automatic fish resource investigations.

[0005] (2) Most of the traditional automatic fish resource investigation devices adopt the lift-net fishing method, that is: using the columns on both sides of the land base, passing the fishing net through the steel wire rope, starting the winch to lower the fishing net regularly for fishing, and then using a fishing boat to catch the fish in the net. It is time-consuming and laborious, and the fishing net capture effect is poor, and it is difficult to realize the fully automatic fishing, counting and releasing process. Summary of the Invention
