Effectiveness of Light Using on the Number of Giant Lift Net Catches in Barru District, Indonesia

Abstract

Aims: This study aims to determine the effectiveness of the use of light on the catches of the Giant lift net. Place and Duration of Study: The research was conducted for six months, from March to August 2022. The research was carried out in the waters of Barru Regency, South Sulawesi Province. Methodology: Data collection was carried out using survey and interview methods as well as literature studies. Field data collection is carried out by participating in direct operations with fishermen. Primary data includes catch (main catch), data on the duration of the stages of catching (setting time, towing time, and hauling time).  The data collected from the interviews are the catch (species, kg/trip, tail/trip) and the trip period. Sampling of the catch is done by taking the fish caught by the Giant lift net per trip. Furthermore, data regarding the description of the Giant lift net was carried out by means of interviews, observations and direct measurements of fishing gear. Secondary data (desk study) will be obtained from an inventory of official publications and fisheries statistical data from the local government. Results: The effectiveness of using the number of lamps and the wattage of the lamps is directly proportional to the catch, the more and brighter the LED lights are used, the more catches will be. The most optimal watt size used in the operation of the Giant lift net is 300-400 watts. The color of the light that is good for using the Giant lift net operation is white.
