Abstract
Circadian variations in gut repletion were observed in adults of Acartia clausi, based on fluorescent pigments measurements. Maximum values lies between 2.00 and 8.00 p.m. and minimum values between 2.00 and 8.00 a.m. This variation which is associated with a less important variation of the concentration of organic particles in water, is assumed to result from a circadian variation in filtration rate. This assumption is discussed on the basis of a rough simulation of the variation of gut repletion. Daily ration estimated according to the observed gut repletion values lies between 35 and 86% of the body organic dry weight.
