| Abstract: | Results of the present study demonstrated that a specific combination of spawning substrate and water current was indispensable for the spawning of mature Japanese dace, Triborodon hakonensis. It became evident that the environmental factors acted as a trigger for endocrine changes leading to final maturation in this species. |
