Herichthys minckleyi (Kornfield & Taylor, 1983)

保育: Herichthys minckleyi 被評鑑為國際自然保育聯盟瀕危物種紅皮書名單中的 (VU) 易危的 (1996). Back in the 1990s Hemichromis bimaculatus was introduced in Poza Churince, the species has radiated to other springs. Efforts to eradicate it had been unsuccessful.

Because of the motivation of the Desert Fishes Council to local people in Cuatro Ciénegas and Mexican institutions, a promotion was carried out and the area was declared a protected area in 1994 (Área de Protección de Flora y Fauna). This is a status of limited legal protection, under what is conferred to a national park. It is particularly directed to the flora and fauna. The valley has been supplied by people and installations that serve to watch it. However, the biggest aggressions are coming from outside of the valley and are not directly focused on the flora and fauna, as the extraction of water from the ground of adjacent El Hundido Valley, used in sprinkle irrigation of alfalfa fields in the desert, to grow food for milch-cows, have had an effect on the water level in Cuatro Ciénegas. The effect has been dramatic and some of the shallow lagoons have been dried. This event turned into a legal war against the powerful milk industry, with mixed results. More recently (2014), the major of the town was accused to grant a permission to extract water from springs, which again drought some areas. It calls attention that a channel built to extract area from La Becerra has not been dismantled by the local government, indicating the intention to use it when possible. The loss of the habitats in Cuatro Ciénegas would have a tremendous effect given their biological heritage importance.
