Abstract
Over six thousands Japanese macaques (Macaca fuscata) have been killed or trapped each year since 1990 as “agricultural pests”. Biological data such as reproductive parameters, however, have as yet hardly been collected from those individuals killed for the purpose of population management. We provide a manual for the basic techniques of age determination, body size measurement, evaluation of reproductive and nutritional conditions, sample collection and preservation. We also propose a plan to construct a data-base from these data.
