Abstract

This study aims to analysis at the composition of fish catches and the fishing effectiveness of fixed lift nets fitted with LED lights of varying color combinations. This research was carried out from May to June 2019, located in the waters of Pangkajene Regency and the Islands. Two fixed lift nets units, 16 white light Emitting Diode (LED) lights and 16 pairs of white blue and yellow combination lights, Global Positioning System (GPS), Stop watch, Digital scale, Digital camera, Logbook, Meter, Current meter, Thermometer, Refractometer, and Lux meter. The research method used in this study is Experimental fishing in fixed lift nets fishing operations using LED lights. Experimental research of white and white combination LED light color (control), and blue, white and yellow LED light color (Treatment) used in 2 fixed lift nets. The fixed lift nets used is 15 meters long and 15 meters wide with a height of 25 meters from the seabed to the top pole with a building height of 10 meters above sea level. The data collection technique was carried out by following directly the catching operation of two fixed lift nets with different color combinations of lights. The data collected is the position of the fishing ground and catch data. Data analysis was carried out qualitatively and quantitatively. Qualitative analysis by looking at the technical aspects of operations on the fixed lift nets and data tabulation. Quantitative analysis was carried out using statistical methods and comparison of fish catches using two treatments using LED light colors. The results show that the composition of fish catches using color combinations (white, blue and yellow) shows higher yields when compared to white. The composition of the catch in the fixed lift nets is divided into three groups, namely the main catch (main catch), bycatch (bycatch) and discarded catch (discard). The use of a combination of LED lights on the fixed lift nets got a catch of 1,347.21 Kg, while the use of white LED lights got a catch of 906.21 Kg. The difference between the catches of the two treatments was 441 kg or 49% of the fish caught using white LEDs. From these results it can be concluded that the use of color combinations of LED lights is more effective than the use of white LED lights.
