“…White‐spotted charr and masu salmon typically follow fluvial or anadromous life histories and do not use lacustrine habitat for rearing ( O. masou —Tsiger, Skirin, Krupyanko, Kashkin, & Semenchenko, ; Morita & Nagasawa, ; S. leucomaenis —Savvaitova et al., ). Naturally adfluvial white‐spotted charr are only known to occur in Lake Peschanoe, Russia (Pichugin, Sidorov, & Gritsenko, ), whereas adfluvial masu salmon are present in at least five natural lakes in Japan (Kasugai et al., ; Leonard, Iwata, & Ueda, ; Osanai, ; Yamamoto et al., ). In adfluvial populations, white‐spotted charr migrate into lakes at age 0+ and 1+ (Yamamoto, Nakano, & Tokuda, ), while masu salmon migrate at age 1+ and 2+ (Tamate & Maekawa, ).…”

“…In contrast, adfluvial individuals in eastern Russia, known as "baydarka," primarily occur in naturally land-locked lakes where they constitute nonanadromous populations (Kurenkov, Gorshkov, & Tolstyak, 1982 2007). Naturally adfluvial white-spotted charr are only known to occur in Lake Peschanoe, Russia (Pichugin, Sidorov, & Gritsenko, 2006), whereas adfluvial masu salmon are present in at least five natural lakes in Japan (Kasugai et al, 2014;Leonard, Iwata, & Ueda, 2001;Osanai, 1962;Yamamoto et al, 2000). In adfluvial populations, white-spotted charr migrate into lakes at age 0+ and 1+ (Yamamoto, Nakano, & Tokuda, 1992), while masu salmon migrate at age 1+ and 2+ (Tamate & Maekawa, 2000).…”

Salmonid fishes may reside within or migrate between stream and lake habitats, or undergo anadromous migrations between freshwater and the ocean. While the degree of anadromy of salmonids has been thoroughly compared, no analogous review has examined the degree of lake use. To assess the extent of reliance on lake habitat in this family, we considered 16 species of salmon, trout and charr from the genera Oncorhynchus, Salmo and Salvelinus, comparing their (a) use of lakes as spawning habitat, (b) rearing strategies in lakes, and (c) occurrence and diversity of lacustrine trophic polymorphism. In identifying the primary life‐history patterns of each species and exploring the lesser‐known lacustrine behaviours, we found that the extent of reliance on lakes exhibits a negative association with the degree of anadromy. Oncorhynchus rely least on lakes, Salmo to an intermediate level and Salvelinus the most, opposite of the general prevalence of anadromy among these genera. Lakes are critical to adfluvial and lake‐resident salmonids, but they also support anadromous and fluvial life histories by providing spawning, rearing, overwintering and/or summer refuge habitat. Adfluviality, although a non‐anadromous life history, consists of similar migration‐related traits and behaviours as anadromy, including the parr–smolt transformation, sex‐biased patterns of migration and residency, and the presence of precocious males. Lakes support life‐history variants, reproductive ecotypes and trophic morphs unique to lacustrine habitat. Therefore, conservation of salmonids is dependent on maintaining the diversity and quality of their habitats, including lakes.
