  • Abstract

    This research was conducted to explore how fish react and behave when exposed to electric currents during fishing. A total of 160 adult three spot gourami (T. trichopterus) were examined, each measuring approximately 9.75±0.44 cm in total length. The study was performed in a circular tank 180 cm in diameter and 80 cm in height. A Yuasa NS YTZ5S 12-volt, 5 Ah battery served as the electricity source. Fish behavior was monitored using a high-definition video camera capable of capturing 1080 × 60 fps. The findings revealed that at a distance of 30 cm from the electrodes and within 2.35 seconds, the fish exhibited increased swimming speed; signs of distress, fin extension, mild fainting, and tension; a slightly bent body and dorsal fin; and gill valve movement. After 4.15 seconds, the fish exhibited a loss of balance, mouth protrusion, increased fin activity, and a decreased response to external stimuli. Between 5.80 and 8.25 seconds, the fish completely lost balance, became rigid and unresponsive, and exhibited minimal, weak movements. At 20 cm from the electrode, the fish showed signs of anxiety and fainted within 8.10 seconds. At 28.35 seconds, there was partial loss of balance, and between 36.25 and 44.44 seconds, a total loss of balance and near-fainting occurred. However, at 40 cm from the electrode, the fish showed no response due to the extremely weak electric current (0.00–0.91 Ah).
