アメリカザリガニ
In Spain, crayfish is called ' (lit. "river crab"). They used to be widely consumed, especially in Castile and León and Aragon, but over-fishing and the introduction of non-native crayfish species (e.g. "Procambarus clarkii", commonly called ') led to a dramatic decline in crayfish population. Nowadays they remain as a seasonal delicacy, usually stewed in tomato sauce, although fishing the native crayfish is strictly forbidden since the species is nearly extinct. Instead of the native crayfish, it is common to fish "Procambarus clarkii" or "Pacifastacus leniusculus", also present in most of the Spanish rivers.
