Fishing nets are tools used in fishing floating in the ocean for a period of 10 to 48 hours, while being able to travel in multiple directions. This leads to problems such as uncertainty in the location of fishing gear, losses. The marine environment has experienced increased severity due to the disposal of fishing gears. The government is working to reduce dumping and loss of discarded fishing gears by tracking location of nets using Styrofoam and flags. Moreover, companies are also developing electronic buoys for monitoring fishing nets and gears. However, conventional electronic buoys have disadvantages, such as limited range, increase in power consump-tion, data loss, and unreliable communication. In this paper, we developed an electronic buoy to monitor fishing nets in real-time. The buoy aims to prevent fishing gear loss and theft by monitoring the location of fishing gears, fishing grounds, and catch information. This system attaches to fishing gears during hauling and transmits real-time location information and operation data of the fishing net to vessels, allowing for easy monitoring. To overcome limitations, we improved communication distance by making our own transmit-ter antennas through comparative experiments. In addition, we improved performance of low-power and long-distance communication functions by introducing LoRa (Long Range) communication technology.
Abstract
Fishing nets are tools used in fishing floating in the ocean for a period of 10 to 48 hours, while being able to travel in multiple directions.

The government is working to reduce dumping and loss of discarded fishing gears by tracking location of nets using Styrofoam and flags. Moreover, companies are also developing electronic buoys for monitoring fishing nets and gears. However, conventional electronic buoys have disadvantages, such as limited range, increase in power consump-tion, data loss, and unreliable communication. In this paper, we developed an electronic buoy to monitor fishing nets in real-time. The buoy aims to prevent fishing gear loss and theft by monitoring the location of fishing gears, fishing grounds, and catch information. This system attaches to fishing gears during hauling and transmits real-time location information and operation data of the fishing net to vessels, allowing for easy monitoring.
