“…1: 14') and Amur-Ussuri (14''), which would be consistent with the conclusion of Zolotukhin (2019). Such distinction is all the more obvious, since the spawning range of the autumn chum salmon of Amur River basin is divided by the type of spawning grounds: in the lower reaches of Amur River, water in most spawning grounds comes from parafluvial springs, while upstream, its spawning grounds are located at discharges of springs (Zolotukhin, 2019). Moreover, the population samples of the autumn chum salmon of Amur-Amgun ecoregion are located on the edge of the genetic cluster of autumn Amur chum salmon (Fig.…”

“…According to our approach, the Lower Amur autumn chum salmon could be distinguished into not one, but two EGUs: Amur-Amgun (Fig. 1: 14') and Amur-Ussuri (14''), which would be consistent with the conclusion of Zolotukhin (2019). Such distinction is all the more obvious, since the spawning range of the autumn chum salmon of Amur River basin is divided by the type of spawning grounds: in the lower reaches of Amur River, water in most spawning grounds comes from parafluvial springs, while upstream, its spawning grounds are located at discharges of springs (Zolotukhin, 2019).…”

Abstract— Using the example of chum salmon Oncorhynchus keta in the Amur zoogeographic province, we review the principle of subdividing the species into population groups. On the basis of zoogeographic zoning and biological boundaries of chum salmon groups defined by the spawning areas, taking into account the distribution, migration, and reproduction, as well as estimates of their differentiation using microsatellite DNA markers, we identified eight ecogeographic units in the Amur province. In the Amur zoogeographic region of this province, these included the summer chum salmon of the Amur-Amgun ecoregion and the autumn chum salmon of the Lower Amur (Amur-Amgun and Amur-Ussuri ecoregions); in the Shantar zoogeographic region of the province, the Uda-Tugur and Ulban groups; in the Sakhalin part of the Amur province, groups from the northwestern and northeastern Sakhalin, as well as summer and autumn chum salmon from the Poronai River. These ecogeographic units can be considered as basic spawning management units of chum salmon for this part of the species distribution range.

“…While pink salmon have been seen attacking other fish on the spawning grounds, the redd-guarding behaviour of females and mate-guarding behaviour of males is typical for all salmon species (Quinn 2018) including coho salmon (Fleming andGross 1994, Kitano andShimazaki 1995), Chinook salmon (Anderson et al 2015), and kokanee (Morbey 2003). It is unlikely that salmon attack each other in the marine phase as extensive analyses of salmon body injuries from at-sea catches do not reveal any wounds inflicted by other salmon (Zolotukhin and Kaplanova 2005).…”

The Northern Hemisphere Pink Salmon Expert Group Meeting was held on October 2-3, 2022 in Vancouver, Canada, immediately preceding the International Year of the Salmon (IYS) Synthesis Symposium. The rapid expansion of pink salmon was the theme for the meeting, and experts came together to discuss the current state of knowledge for pink salmon. Specific topics of focus included the range expansion into the Atlantic and Arctic oceans, trends in distribution and abundance, research and monitoring approaches, potential inter-specific interactions, mitigation efforts, and plans for future collaborations. The outcomes of the meeting were presented at the IYS Synthesis Symposium and are further disseminated through this NPAFC Technical Report. The Executive Summary section of this report provides a brief background, a condensed overview of each topic, and concludes with overarching takeaway messages that are intended to guide future collaborations.

The monitoring of chum and pink salmon escapement to spawning grounds in the Amur River basin was stopped in 2009. To start it again, a proved choice of the rivers is necessary for adequate controlling of these species number, by the spawning habitats of their population groups within the basin. For this purpose, results of the monitoring in 1949–2000 and the data on human settlements in the medieval times are analyzed. The lower reaches of the Amur were anciently inhabited by the paleoasiatic Nivkh people and the upper reaches where the fall chum spawned in spring waters were inhabited by the people of Pokrovskaya archeological culture — their burial grounds coincided with the spawning area of fall chum salmon. To reach these spawning grounds, fall chum salmon migrated up to the distance of 3427 km from the Amur mouth, but since the 20th century they occur rarely in the upper reaches of the Amur, in particular within Chinese territory where they are not observed in more than 50 years; recently they spawn in spring waters at the distance 500–1200 km from the Amur mouth, mainly in its right tributaries. The reproduction centers of other two populations of chum salmon, as the summer chum and fall chum breeding in hyporheic waters, are located in the Amgun River basin (the lower left tributary of the Amur). The fourth population is the lake chum salmon breeding in spring waters of Lake Chlya located on the left bank in the lower reaches of the Amur River. Centers of reproduction for both pink salmon populations, differentiated by even and odd years of spawning, are located in the Amgun River. Several test rivers are selected within all mentioned centers of reproduction, they are: Kerbi, Duki, Im, Somnya, Aksha, Khilka, Beshenaya, Gur, Anui, Khor, Kur, and Bira. This list is similar to the list of the rivers where chum and pink salmons were monitored in the 20th century
