“…Pink salmon fry transiting Lake Aleknagik, Alaska, USA, rear there for up to a few weeks, growing 30–67% faster in fork length/day than sympatric sockeye salmon fry during that time (Robins, Abrey, Quinn, & Rogers, ). In lake systems of the Kuril Islands, Russia, the fry of river‐spawning chum salmon begin feeding in coastal marine waters, whereas those of lake‐spawning fish rear in the lake for a short period before entering the sea later that same year (Kaev & Romasenko, ; Zelennikov, Pogodin, & Otstavnaya, ; Zhivotovsky et al., ). Only one naturally adfluvial specimen has been recorded for pink salmon, a 2‐year‐old male that reared to maturity in Frazer Lake, Alaska, USA, after fishways allowed colonization above what had been a barrier waterfall (Hennick, Edfelt, & Eaton, ).…”

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.
