- 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.
- Eel — A migratory teleost fish of the Anguillidae family, characterized by a highly elongated, cylindrical, and snake-like body covered with a thick layer of mucus and microscopic scales. This remarkable species, scientifically known as Anguilla anguilla, matures in European continental freshwaters and migrates vast distances to the Sargasso Sea to reproduce in the deep ocean, possessing significant economic and culinary value due to its rich and flavorful meat.
