- Alos — An archaic or regional popular name derived from scientific nomenclature (genus Alosa) used to designate various fish species in the Clupeidae family, specifically the Danube shad or its adjacent lineages. This euryhaline migratory fish is structurally characterized by an elongated, hydrodynamic body and silvery scales, studied within population dynamics in European hydrographic basins.
- Alpmus — An archaic or regional popular name extracted from old fishery lexicons, sometimes used to designate a small river fish or a variety of lamprey (larva or adult) adapted to cold mountain waters. In a local structural and ecological context, the term reflects empirical names used by fishing communities along the Carpathian valleys.
