Abstract

As fish receive signals from lures, this experiment is aimed at identifying different types of signals emitted from the signal source, i.e. lures.<br>Data gathering is done, based on three kinds of signals namely visual, acoustic and the signal on the lateral lines of fish body, i.e. molecular vibration of water.<br>Visually, the result shows that in most of the cases, no apparent visual change is seen when the lures were not in motion and when they were vibrating.<br>In acoustical analysis, spectral distribution of the signals fully spanned the frequency band. Thus it is assumed that lures are noise generators.<br>Since molecular vibration of water cannot be measured directly, it is estimated from the vibration on the lure lines. It is found that lure line vibration is highly correlated with current speeds.
