Priorities for Captive Maintenance of Mexican Goodeids – January 2006

Received from Dr. John Lyons, 17 January 2006. He just returned from Mexico compiling this.


Extinct (no captive populations available):
Characodon garmani
Extinct in the Wild (captive populations available):
Skiffia francesae

Critically Endangered:
Allodontichthys polylepis, Allotoca goslinei
Allotoca maculata, Allotoca meeki
Allotoca zacapuensis, Ameca splendens
Ataeniobius toweri, Chapalichthys pardalis
Chapalichthys peraticus, Characodon audax*
Characodon lateralis*, Girardinichthys viviparus
Hubbsina (Girardinichthys) ireneae, Hubbsina (Girardinichthys) turneri
Neotoca (Skiffia) bilineata , Neophoorus (Allotoca) regalis
Xenoophorus captivus*, Zoogoneticus tequila

Allodontichthys hubbsi, Allotoca dugesii*
Skiffia lermae, Skiffia multipunctata
Xenotoca eiseni*

Allotoca diazi , Girardinichthys multiradiatus


Allodontichthys tamazulae, Allodontichthys zonistius
Alloophorus robustus*, Allotoca catarinae*
Chapalichthys encaustus, Goodea gracilis (=atripinnis?)
Ilyodon cortesae, Ilyodon whitei* (inc. I. lennoni)
Xenotaenia resolanae, Xenotoca melanosoma
Zoogoneticus quitzeoensis*

Relatively Secure:
Goodea atripinnis* (inc.
G. luitpoldi), Ilyodon furcidens* (inc I. xantusi)
Xenotoca variata*


Note: Status categories are not official Mexican government designations, but are based (with some updates) on Domingúez-Domingúez, O., N. Mercado-Silva, and J. Lyons. 2005. Conservation status of Mexican goodeids: Problems, perspectives, and solutions. In press, Proceedings of the International Livebearer Conference, and De La Vega-Salazar, M. Y., E. Avila-Luna, and C. Macías-Garcia. 2003. Ecological evaluation of local extinction: the case of two genera of endemic Mexican fish, Zoogoneticus and Skiffia. Biodiversity and Conservation 12:2043-2056. Species with an asterisk have large amounts of morphological and/or genetic diversity and have distinctive populations worthy of captive maintenance.
