Resumen

Una prioridad en este milenio, es proteger, conservar, aprovechar y manejar sustentablemente los humedales, mediante actividades productivas de bajo impacto ambiental (como la pesca), que son fuente de alimento y empleo, áreas de des canso par sociedad y prestan valiosos servicios ambientales (2); por ello en la presa del Salto (Valle de Guadalupe) se realizan investigaciones ictiológicas, limnológica, pesqueras y sanitarias que fortalecen la conservación de los ecosistemas.
