Professor Gary Grossman of the Warnell School of Forestry and Natural Resources, Athens, GA, US, not only writes about trout, see: ‘Not all drift feeders are trout: a short review of fitness-based habitat selection models for fishes’ in: Environmental Biology of Fishes, 05 / 2013; 97(5), he also sings about them, self-accompanied on a ukulele [click to hear .mp3 sampler].
In southern mountains ridged with age
Streams run fast o’er steepened grades
Pools and riffles stair-step down
Neath oak and hemlock’s shady boughs
Prey are sparse in Southern hills
Sedges, mayflies, stoneflies fill
But mostly tiny midges drift
Growth is slow, full stomachs missed [cont.]”
The professor has been kind enough to provide some extra detail for Improbable :
“The European residents of the Southern Appalachians called the native brook trout ‘Speckled Trout’ because of their light markings on a dark background. Genetically, these trout (charr actually) deserve subspecific status at least and they are in bad shape due to hybridization with stocked northern brook trout, potential competition with invasive rainbow trout, and habitat degradation. The song, besides describing their biology in a pleasing format, is a paean to their continued existence.”
The professor’s new CD ‘Natural Voices’, which also features songs about foraging theory, taxonomy, short-tailed shrews and red foxes, is available here. And it can also be purchased for direct download here.
 The plural of ‘Trout’ is ‘Trout’ or less commonly, optionally, ‘Trouts’
