| 内容記述 | We visually searched for conspecific and intergeneric mating behaviors of red-spotted masu salmon Oncorhynchus masou ishikawae and char Salvelinus leucomaenis at 16 river sites in Gifu Prefecture, located in central Japan. The results indicated that conspecific mating behavior was observed 90 times in red-spotted masu salmon and 54 times in char. In addition, intergeneric mating behavior was observed twice between female red-spotted masu salmon and male char and seven times between female char and male red-spotted masu salmon. Therefore, the former and latter intergeneric mating behaviors accounted for 1.3% and 4.6%, respectively, of the 153 mating behaviors observed in this study. The former was observed during the transition period from the breeding season peak of red-spotted masu salmon to that one of char, whereas the latter was observed at a time when the breeding season of red-spotted masu salmon was almost finished. In addition, the first observation of the intergeneric mating behavior between a female red-spotted masu salmon and male char supports the hypothesis that hybridization between Oncorhynchus masou complex and its mother species occurs in the field. Further, the case of a male red-spotted masu salmon exhibiting sneaking behavior in a male/female char pair was observed for the first time, suggesting that males of different species act as sneakers in conspecific pairs. | |||||
