Here you can find pics and information about some Mexican livebearersí habitat. Near each photo you can read a short description of the environment and a list of the species you can find in the body of water.

 

 

BUSQUEDA (1st photo): This site is located in Lake Zirahuen. Now itís quite difficult to find any goodeids (only a few GOODEA ATRIPINNIS) because of the in introduction of Black Bass (MICROPTERUS SALMOIDES), that is a predator of any small fish found in the same water. In the past here has been collected these species: ALLOTOCA DUGESI, ALLOTOCA MEEKI, SKIFFIA LERMAE, GOODEA ATRIPINNIS and ALLOOPHORUS ROBUSTUS, and some others non Ė goodeid as ATHERINIDS and introduced species as bass ad carps.

In the upper part of this basin , in OPOPEO (2nd photo) (that is a small pond) we can find more goodeids :

ALLOTOCA DUGESI, ALLOTOCA MEEKI, GOODEA ATRIPINNIS, (2 different forms of Goodea : the black (or gray) one and the yellow (golden) one that Omar suppose can be an albino form).

CUTZARONDIRO : This habitat is in the Balsas basin , and we may find here : ILYODON CORTESAE and NOTROPIS BOUCARDI, is the only known locality for I. CORTESAE.

 

EL BORBOLLON LA MAIZA : El borbollon is a spring situated in the upper Cuitzeo drainage. Here we can find : SKIFFIA BILINEATA, S. LERMAE, GOODEA ATRIPINNIS and ALLOTOCA DUGESI. This spring flow to the  Moreli river and to the Cuitzeo lake.

 

EL MOLLINO : is  a spring near Patzcuaro lake, and it is a tributary of the lake itself. Here we may find :

ALLOPHORUS ROBUSTUS, ALOTOCA DUGESII, ALLOTOCA DIAZI , SKIFFIA LERMAE and GOODEA ATRIPINNIS.
