With weight of eye lens as a reference, it is proved that the age criterion could be used to distinguish young less than 6–7 months old from those older. This is a pragmatic method to analyze age composition of game-bag in the early period of shooting season when younger holds a large proportion in the hare population. It also is useful in judging the age of hares trapped and estimating the effects of predation on the hare population structure.展开更多
