Abstract

The phototactic behavior of COTS to steady and flashing LED light spectra such as blue (473nm), yellow (595nm), red (625nm) and white was observed/monitored using infrared closed circuit television (CCTV) camera. Steady LED light spectra had a significant effect on the locomotion rate of COTS (ANOVA; p<0.05) and there was no significant effect using flashing LED light spectra (ANOVA; p>0.05). COTS can be considered to be positively phototactic to steady blue spectrum (473 nm) with mean locomotion rate of 30.35 cm/min and negatively phototactic to steady white light with mean locomotion rate of 28.44 cm/min. Blue and white LED can act as photo stimulant either as attractant or repellent to crown-of-thorns starfish.
