Artificial light in fisheries has been one of the most advanced and successful method
for capture purposes. As the technology getting advanced, it had evolved from
incandescent lamp, halogen lamp, metal-halide lamp, and Light Emitting Diode are the
conventional fishing lamp for fisheries industry. This project utilised Laser Diode (LD)
with 3 colours red, blue, green as light sources. The main objectives in this research
project are to study the ability of LD to attract fish, to determine their spectrum colour
and to evaluate their power consumption. The process sequence is firstly the lamp
prototypes preparation. Next, is the lighting setup then the fish attraction phase and
lastly is spectrum determination. The result shows that blue (450nm) and green
(532nm) colour wavelength able to attract the fish and LD saves 25% energy of the
power consumption. In conclusion, LD developed an alternative light fishing
technology as for a new approach.
