Management Factors
Activities that are known to be detrimental to the Yaqui Catfish populations are the de-watering of habitats through stream usage and re-routing, stream impoundment, channelization, domestic livestock grazing, timber harvesting, mining, road construction, polluting, and stocking non-natives.
Threats: aquifer pumping; reduction in stream flows; water diversion; drought; hybridization, competition and predation by nonnative fishes.
Management Needs: protect San Bernardino aquifers, and Leslie Creek and Black Draw watersheds to ensure adequate perennial flow; ameliorate effects of nonnative fishes; reintroduce into suitable habitats within historical range; stabilize and protect populations in Mexico.

Famous quotes containing the words management and/or factors:
“No officer should be required or permitted to take part in the management of political organizations, caucuses, conventions, or election campaigns. Their right to vote and to express their views on public questions, either orally or through the press, is not denied, provided it does not interfere with the discharge of their official duties. No assessment for political purposes on officers or subordinates should be allowed.”
—Rutherford Birchard Hayes (1822–1893)
“Language makes it possible for a child to incorporate his parents’ verbal prohibitions, to make them part of himself....We don’t speak of a conscience yet in the child who is just acquiring language, but we can see very clearly how language plays an indispensable role in the formation of conscience. In fact, the moral achievement of man, the whole complex of factors that go into the organization of conscience is very largely based upon language.”
—Selma H. Fraiberg (20th century)
