High Quality Content by WIKIPEDIA articles! Achondrostoma salmantinum is a species of freshwater fish in the Cyprinidae family inhabiting waters off the coast of the Iberian Peninsula. The population of the Achondrostoma salmantinum is rapidly declining. A major cause of this decline, anthropogenic disturbance, reduced stocks by 52%. Factors negatively impacting Achondrostoma salmantinum population include water extraction (including hydrological infrastructures), introduced species, climate constraints, pollution and overexploitation. Some other factors that are also causing the fresh water fish to become endangered are forest fires which put fuels in the air, fisheries, and gravel extractions, where the people are removing the gravel from the edge of the lake.
