|Abstract: ||Abstract: In order to investigate the role of light in triggering nocturnal feedingof black porgy(Acanthopagrus schlegeli),animals of 12 cm to 14 cm in length,were acclimated under normal photoperiod for more than one week.Theexperimental individuals were fed every four hours under three photoperiodregimes:continuous light for four days,normal photoperiod for three daysand continuous darkness for another three days.Three repeated experiments(May 1-11,16-26 and June 1-11,1989)were done with simultaneous recordingof water temperature in the second experiment.The recorded temperatures did not indicate any concomitant change withthe change of light.Their diel feeding revealed cyclic trend with peaks atnight under three conditions,namely continuous light,normal photoperiod andcontinuous dark.The first one or two days of continuous light treatmentmight cause stress on fish with arrhythmic feeding.In summary,the rhythmic feeding of the black porgy may be regulatedby some endogenous mechanism and the light as an exogenous factor isprobably evoking a short-term effects.|
