Pink Salmon | Oncorhynchus gorbuscha

Exceptionally low numbers of pink salmon (Oncorhynchus gorbuscha) showed up in the rivers of Japan during the breeding season of 2024. Though the reason for this stark absence is not clear, it is possible that warmer than normal ocean temperatures played a role. Despite the discouraging circumstances, this lone male and a handful of females gathered beneath a small waterfall in preparation for spawning, providing some hope for the future. Photographed in Hokkaido, Japan.
