The Gillnet Fisheries Group Partnership Program in the Bulak District of Surabaya is one of the Community Service activities which carried out by Hang Tuah University in collaboration with the Research and Technology Ministry and the Indonesian Traditional Fishermen Group. The activity carried out is to provide a solution by assisting the use of sound wave based fish calling equipment as fishing aid to gill nets so that fishing operations are expected to be more efficient and the number of catches will increase. The method used in this partnership program is to provide assistance to gill net fishermen groups in the Bulak District of Surabaya. The activity was held on Friday, June 14, 2019 and was attended by 15 gill net fishermen. The tool socialized for its use in the mentoring program is a sound wave based fish calling device which has a frequency between 500-1000 Hz. Implementation of assistance to gill nets fishermen using sound wave based attractors is expected to be a solution in the sustainability of gill net fishing gear in the future by applying appropriate technology.
