Abstract

The game managers annually complete the stock estimation of different game species. This data are the basis of the game management planning. The result of the estimation is very different from the real stock size. The population dynamic model (elaborated by the authors) use the bag size data and some ecological parameters of big game species to calculate the stock size. We calculated the red deer population stock size in Somogy county using of known bag size data since 1970. The result shows that the stock size estimated is unlike calculated. According to the model arithmetics in the ratio of female stock decreased strongly, the sex ratio has changed radically in favor of tags. The red deer stock became younger.
