Аннотация:An experiment was set up to estimate the rate of zooplankton consumption by the three-spinedstickleback Gasterosteus aculeatus (Linnaeus, 1758) at different predatordensities. A differential equationdescribes the dynamics of zooplankton abundance depending on duration of predator feeding. The derivedfunction accurately characterizes the rate of zooplankton consumption by stickleback in the experiment,demonstrating a good agreement between the theoretical prerequisites and the experimental results. The relationshipbetween changing a number of victims during predation, its mortality and consumption rate wasrevealed. The hypothesis ofconsumption rate proportionalto the number of predators was tested. A comparativeanalysis of ingestion rate as a function of time and a function of prey density was performed.
