ABSTRACT:
An apparatus for monitoring a water quality by raising an aquatic living thing in a monitoring water tank 1. The monitoring water tank 1 is taken through a camera 12 to be displayed on a television 14. A monitoring area E comprising a plurality of sensor points is set on a television scene through a light pen, and a fish sensing device 13 senses variation of the sensor points in luminance level to continuously detect the moving positions of fish F, F' under observation. A personal computer 15 detects, on the basis of the moving positions of the fish under observation, whether or not each of the fish under observation takes any one of a plurality of abnormal action patterns, and conducts an alarm operation if both the two fish F, F' under observation assume any abnormal action pattern.
