Embodiment 1

[0058] Embodiment 1, (referring to Figure 4 ) completely block the Michigan River, preventing the Asian carp from invading the Great Lakes region northward.

[0059] The original intention of the present invention is to respond to the public appeal of the Michigan State Environmental Agency and to invent an effective method to ensure the interception of all Invasive carp (priority targets are bullhead and silver carp).

[0060] With more than 100 sets of the present invention image 3 The long-line cages of the smart electric field shown are densely deployed on a section of the river about 10 kilometers long according to the way of laying across the river and along the bank, forming a complete blockade area for carp. System image recognition is set to bighead carp, silver carp and herring. Any bullhead, silver carp, and herring that try to swim north will have thousands of opportunities to be lured into the prison fish cage by lights and bait during this section. This syst...

Embodiment 2

[0061] Embodiment 2, Quantitative fishing of perch with high economic value.

[0062] The Zhangjiazhuang Reservoir in a certain county in China supplies the whole county with free-range sea bass in an ecological way. In the past, the nets were cast regularly once a month, and the fishermen selected them manually. The most prominent problem was that there were too many harvests in the fishing day, so they could only be scattered by the fishmongers in the county for a short period of time. After raising for several weeks, the death loss of fish in this process is relatively large.

[0063] Using the present invention, "perch, the length is greater than 1 foot, and the number of catches is counted 2000 per day" is set on the image recognition. In this way, every day when the intelligent control counts and finds that the number reaches, the electric field at the mouth of the fish luring channel will be turned on to stop fishing, and other miscellaneous fish and small fish with ins...

Embodiment 3

[0064] Embodiment 3, catching rare A fish.

[0065] Scientists have discovered that there is an extinct A fish living in the B sea area of ​​Africa, and hope to catch one for scientific research. However, due to its rarity, it is rare for local fishermen to encounter one in a few years. It is not suitable in terms of time and economic cost to hire someone to fish or to fish by yourself every day.

[0066] With the simplest configuration of the present invention: a fish prison net cage plus a fish luring channel, the image recognition is set to A fish, the control unit and image recognition equipment are installed in a floating box with solar panels, and the fish prison nets on the seabed are connected with cables. The cages are connected together, and after A fish is caught in the net, a radio signal is sent back to inform scientists to go to B sea area to salvage the prison fish cage. This device was placed in the B sea area without care, and the scientists successfully caug...

Abstract

The invention relates to an intelligent fishing method which generates / removes electric fields at different positions to schedule behaviors and positions of fishes according to fear of the fishes of electric fields. The invention provides an intelligent electric field net cage fishing device by the method, the device comprises a fish luring channel, a fish imprisoning net cage, a harvesting net cage, a lifting device and a service cage, the fish luring channel is used for luring target fishes to enter the net cage and comprises a lighting source, an underwater camera, a bait spreading pipe, aproximity sensor and a plurality of repellent electrode groups, the fish imprisoning net cage is used for temporarily imprisoning the fishes entering the fish luring channel and provided with a plurality of electrode groups and a fish outlet, the harvesting net cage is used for harvesting captured fish schools and comprises a positioning frame (31) and a grille door, the fish inlet can be opened and closed by the grille door, the lifting device is used for lifting the harvesting net cage (3) to leave from the water surface, the service cage provides support services such as baits and electricfield control for underwater devices and comprises a feeding pipe, a multi-core signal and control cable, a feeding pump, a bait tank, an intelligent controller, an image recognition unit and the like. The intelligent fishing method has the advantages that preset kinds of fishes are caught according to requirements, entrance of non-target fishes is refused, and the device is efficient and fully automatically runs in 365 days in a year.

Description

technical field [0001] The invention belongs to the field of fishing devices. Background technique [0002] In the 1970s, the exotic species of Asian carp (a collective term for eight common Chinese freshwater fish species including bullhead, silver carp, etc.) was introduced to the southern United States to improve water quality in wastewater ponds. These carp escaped into local waterways and eventually invaded other states across the United States. Mature bighead carp or silver carp can grow up to 40 kg and eat more than 20% of their body weight in food every day. The Asian carp has seriously destroyed the living conditions of local fish and caused associated ecological and economic problems. [0003] Since the 1990s, various measures to control Asian carp have been attempted, but with little success. The current invasion vanguard of Asian carp has reached the Michigan River on the border between the United States and Canada, only tens of kilometers away from the Great ...
