Description

The feeding experiments of the guppy, Poecilia reticulata, were carried out under various bait concentrations. A water flea, Daphnia pulex, was used as the bait. 1) The guppy continously feeds on the bait all through the day, when supplied with a sufficient amount. 2) The consumed number of baits can be described as a function of the time required for feeding, as follows, n=N(1-e^<-at>) where n is the number of baits consumed till the time t, N is the initial concentration of bait and 'a' can be expressed in the present experiments as the function of the initial concentration of bait and the full function can be described as, n=N(1-e^<-5.468t>/N^<0.913>) 3) The equation between the number of baits consumed and the initial concentration of the bait showed good agreement with the equation obtained by IVLEV (1955). This equation is described as, r=R(1-e^<-ξp>) where R is the maximum amount of food consumption at a definite time and ξ is the coefficient of proportionality.
