Abstract
Photoelectric methods of measuring the activity of aquatic organisms allow unrestrained movement of the animal being studied but may disrupt exogenously controlled rhythms if the light is visible. An apparatus is described that uses infrared light-emitting diodes that eliminate some of the problems associated with incandescent light sources. A graph of the locomotor activity data of two pigfish (Orthopristis chrysoptera) which was produced by this apparatus is included.This publication has 0 references indexed in Scilit:
