Morphology

river + shad

The compound is fully compositional: 'river' specifies the habitat/type of 'shad', so a learner who knows both words will naturally infer it means a shad found in rivers (a river-dwelling shad or species of shad). This noun+noun formation is a common, cross-linguistic way to name types and is therefore transparently derivable from its parts.

Etymology

River shad gets its name from a simple picture: a shad swimming into a river to 'lay eggs'. That's why today the name means a type of shad that moves into rivers to 'lay eggs'.
