The significance of saving energy and fish aggregation has been enhanced by a light-emitting diode (LED) fish lamp provided with a fish attraction light pattern. Sheng-Chih Shen and Professor Ming-Chung Fang from the National Cheng Kung University (NCKU) are responsible for the development of this high-brightness LED fish lamp.
The research team of the NCKU used an LED underwater transfer model, energy mapping and biological phototaxis to develop the fish attraction light pattern. This attempt to provide fishing lights with an illumination pattern is the first of its kind.
This LED fish lamp will reduce the total fuel consumption of a ship by 15%-20% and it will also attract the fish in order to prolong the stay of the fish in the light pattern. It has been observed that fishermen in Taiwan and various other regions will avail benefits from the fish attraction light pattern. This LED fish lamp can be used by the fishermen in a safe manner in comparison with convention fishing lamps that emit harmful ultraviolet rays.
Shen stated that the fish lamp has been installed in few of Taiwan’s far-sea and coastal fishing vessels. Shen further added that the modular design of the lamp will reduce the maintenance cost and help in assembling the lamp in an easy manner. Besides this, the angle of the lamp can also be adjusted based on the habit of the fish.
