Embodiment 1

[0019] A method for assisting fish to gather at the entrance of a fish passing facility, comprising the steps of:

[0020] (1) The appearance of the selected target fish has no obvious damage, and the size range of the target fish is consistent with the size range of the fish passing objects in the fish passing facilities, that is, the fish species with a length of 30 cm, and the amount of fish used in the control target is the smallest fish in the river 20% of the closed population (i.e. 500 / species x 20%=100 / species);

[0021] (2) Conduct conditioned reflex training on the target fish. Place the target fish at the starting point of a pool with a length of at least 100 m and a width and depth at least twice the length of the fish. Put the bait at 1-10 m of the fish, and simultaneously generate a stimulus beside the bait (the said stimulus is a light source and a sound source, the wavelength of the light source is 500 nm, and the intensity is 600; the frequency of the sound so...

Embodiment 2

[0026] A method for assisting fish to gather at the entrance of a fish passing facility, comprising the steps of:

[0027] (1) The appearance of the selected target fish has no obvious damage, and the size range of the target fish is consistent with the size range of the fish passing objects in the fish passing facilities, that is, the fish species with a length of 30 cm, and the amount of fish used in the control target is the smallest fish in the river 20% of the closed population (i.e. 500 / species x 20%=100 / species);

[0028] (2) Conduct conditioned reflex training on the target fish. Place the target fish at the starting point of a pool with a length of at least 100 m and a width and depth at least twice the length of the fish. Put the bait at 1-10 m of the fish, and simultaneously generate a stimulus beside the bait (the said stimulus is a light source and a sound source, the wavelength of the light source is 700 nm, and the intensity is 300; the frequency of the sound so...

Embodiment 3

[0034] A method for assisting fish to gather at the entrance of a fish passing facility, comprising the steps of:

[0035] (1) The appearance of the selected target fish has no obvious damage, and the size range of the target fish is consistent with the size range of the fish passing objects in the fish passing facilities, that is, the fish species with a length of 30 cm, and the amount of fish used in the control target is the smallest fish in the river 20% of the closed population (i.e. 500 / species x 20%=100 / species);

[0036] (2) Conduct conditioned reflex training on the target fish. Place the target fish at the starting point of a pool with a length of at least 100 m and a width and depth at least twice the length of the fish. Put the bait at 1-10 m of the fish, and simultaneously generate a stimulus beside the bait (the said stimulus is a light source and a sound source, the wavelength of the light source is 600 nm, and the intensity is 300; the frequency of the sound so...

Abstract

The invention provides a method for assisting a user to gather fishes to an entrance of a fish passage facility. The method specifically comprises the steps that healthy target fishes without trauma are selected for conditioned reflex training, bait is put at the position 1 m to 10 m away from the target fishes, a stimulus is generated beside the bait at the same time, and the target fishes move towards the bait and the stimulus to take in the bait and arrive at the stimulus; the target fishes are driven to the initial point through a blocking net, meanwhile, no stimulus is generated, the distance is enlarged, a stimulus is generated again, but no bait is put, and the target fishes move towards the stimulus; and the trained target fishes are released in a natural river, the trained target fishes in a fish shoal can sense the stimulus and directionally move towards the stimulus due to the conditioned reflex, the fish shoal directionally moves towards the stimulus along with the trained fishes, and the fishes can be assisted in gathering to the entrance of the fish passage facility. According to the method, the efficiency that the proliferated and released fishes and the wild fishes gather to the entrance of the fish passage facility can be improved, and the operating efficiency of the fish passage facility can be improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, and more specifically relates to a method for assisting fish to gather at the entrance of a fish passing facility. Background technique [0002] China's vigorous development of water conservancy projects in recent years has damaged river connectivity and blocked fish migration channels. As an important engineering compensation and mitigation measure, fish-passing facilities require higher and higher levels of design and construction. How to assist fish to find fish-passing facility imports and how to lure fish to fish-passing facility imports is to ensure fish-passing facilities It is one of the key links with good operation effect. How to use the research basis of ichthyology to assist fish to gather in fish facilities has become a new issue of widespread concern in ecological protection and water conservancy engineering. Contents of the invention [0003] In view of th...
