Problems solved by technology

[0002] Existing fishing techniques include nets, fishing, electricity, etc. Among them, net fishing requires a relatively large manpower investment and requires multiple people to operate. The fishing efficiency is very low and fishing is very slow. Electric fish is not environmentally friendly and will electrocute small fry. There is a technology that requires less manpower and can fish with high efficiency, and only catches big fish and not small fish, which is conducive to reducing manpower and improving efficiency

Abstract

The invention discloses a fishing device, which comprises a resistance measuring device and an expanding device. The resistance measuring device is provided with two fixed electrodes, and the optimalsetting of the standard value should be greater than the resistance value of the water but less than the resistance value of the freshwater fish body. The expanding device expands when the resistancebetween the two electrodes is measured at a standard value. The fishing device is covered with bait, and the device can single out the bigger fish depending on the size-setting of the device in principle. The smaller fish cannot swallow the device; whereas the bigger ones can swallow the device and make the balloon expand in the body due to fact that the resistance value of fish body is far less than that in water. As the balloon expands in the fish body, the size of fish is increased, and the fish belly is upwards and floats out of the water surface. The device uses a single chip control. Theenvironment-friendly sustainable fish farm adopts the said fishing device to achieve sustainable fishing. The fishing device has the advantages of easy operation and less manpower input without accidentally injuring fry. The fishing device also innovates a new idea of fishing that is feasible for sustainable batch fishing.
