| Abstract: | We consider age composition of samples of the Lower Amur grayling Thymallus tugarinae inhabiting water bodies of the lower and middle course of the Amur and several rivers of the northwestern part of Sakhalin Island and the southern coast of the Sea of Okhotsk. Age composition of the Lower Amur grayling from the studied samples is not similar because of several reasons. In rivers of the Amur basin, the species has a maximal age of 6+. |
