“…Areas of appropriate substrate may be determined by hydraulic processes and topography, as spawning sites must receive enough wave action or current to prevent accumulation of fine particles but not so much that eggs become dislodged or physically shocked (Ellen Marsden et al., ; Eshenroder, Bronte, & Peck, ; Low, Igoe, Davenport, & Harrison, ). We found no examples of pink salmon, masu salmon, coho salmon, Chinook salmon, bull trout or white‐spotted charr spawning in lakes (Christie, ; Dunham et al., ; Quinn, ; Savvaitova, Kuzishchin, Pichugin, Gruzdeva, & Pavlov, ); these species appear to be exclusively stream spawners, with the exception of pink salmon that also spawn in the intertidal zone of certain systems (Helle, ; Rounsefell, ).…”

“…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., ).…”

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.

“…Populations north of Honshu Island, including Hokkaido Island, Japan, and Sakhalin Island and Kamchatka Peninsula, Russia, are classified as S. I. hucomaenis. They are characterized by large white spots ( Figure 2; Savvaitova et al 2007). The other three subspecies are endemic to Honshu Island, Japan, each with distinctive coloration.…”

“…Dolly Varden and white-spotted char reportedly first mature between 1 and 7 years of age whereas bull trout are believed to mature later, generally between 5 and 7 years of age. Maximum life spans of these species may exceed 10-15 years (Rieman and Mclntyre 1993;Savvaitova 1980;Yamamoto et al 1999;Savvaitova et al 2007). Rapid growth is often associated with movement into more productive environments, including the opportunity for piscivory.…”

“…Migration typically is related to availability of food resources that are distant from natal habitat, and the relative benefits of migration may vary between the sexes (e.g., Jonsson and Jonsson 1993;Hendry et al 2003;Koizumi et al 2006a). Anadromy is common in white-spotted char and Dolly Varden but is more prevalent at higher latitudes (Yamamoto et al 1999;Savvaitova et al 2007) where freshwater food webs are less productive and marine waters provide alternative food resources (Maekawa and Nakano 2002). Anadromy is also known in bull trout (Brenkman et al 2007), though apparently is less common, perhaps because the species' range is more inland in comparison to Dolly Varden and whitespotted char.…”

Evolution, Ecology, and Conservation of Dolly Varden, White spotted Char, and Bull Trout

et al. 2008

We review the ecology and conservation of three lesser‐known chars (genus Salvelinus): Dolly Varden (S. malma), white‐spotted char (S. leucomaenis), and bull trout (S. confluentus). Dolly Varden is distributed across the northern Pacific Rim and co‐occurs with bull trout and white‐spotted char at the southern extremes of its range. In contrast, bull trout and white‐spotted char are naturally isolated, with the former restricted to North America and the latter distributed in northeastern Asia. Though the range of Dolly Varden overlaps with the two other chars, it is most closely related to Arctic char (S. alpinus), whereas bull trout and white‐spotted char are sister taxa. Each species exhibits diverse life histories with respect to demographic characteristics, trophic ecology, and movement. This diversity appears to be tied to environmental variability (e.g., temperature, habitat connectivity), resource availability (e.g., food), and species interactions. Increasingly, these interactions involve nonnative species including nonnative salmonines and changes in food webs related to establishment of species such as Mysis shrimp in large lakes. As humans expand into the remote and pristine habitats that support these three chars, we encourage proactive consideration of the lessons learned where chars have already declined and internationally‐based research and conservation.
