On the 21st, the Hokkaido Research Institute Salmon and Inland Fisheries Research Station announced that this year's predicted autumn salmon migration to Hokkaido is 17.03 million fish, down 24.5% from last year.

This is the lowest predicted figure ever, below 2017's figure (17.37 million fish). The main reason for this is that last year there were few returnees of three-year-old fish across the prefecture, meaning that the return of four-year-old fish, which form the main group, is not expected to be large. There are also concerns about a significant shortage of hatching eggs in the Pacific coastal waters west of Erimo and east of Erimo.

This was explained by Koichi Urabe, chief researcher at the Salmon Resources Department of the Hokkaido Fisheries Research Institute, at a meeting of the Hokkaido United Sea Area Fisheries Adjustment Committee, which will decide on this year's "Implementation Guidelines for Capturing Autumn Salmon Parent Fish and Proper Use."

Last year's number of autumn salmon migrating to Hokkaido (total number of coastal fish catches and river catches) was far below the forecast (34.83 million fish), ending up at 22.57 million fish, a 35% decrease from the previous year. By age, the number of 4-year-old fish (19-year class) was 15.52 million fish, a significant decrease of 35% from the previous year. The number of 5-year-old fish (18-year class) was 4.99 million fish, down from the previous year.
