#fish species
- 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.
- Ruffe — A regional or popular name given to certain small fish species found in fresh or stagnant waters, often applied to the ruffe or the European bullhead, structurally characterized by a large, flattened head and a scaly body; in a rare isolated archaic sense, it can also represent a diminutive for an old woman.
