For fans of Mexican fishes, especially livebearers, the two books written and self-published by the ‘Freshwater Biotopes’ team of Rune Evjeberg and Kai Qvist are essential reading.

Book 1 is extensive and covers numerous habitats in the states of Coahuila, San Luis Potosi, Hidalgo, Michoacán, Quinatana Roo and Campeche, whereas Book 2 is concerned with the highly diverse Yucatan Peninsula.

Focussing not only on the fishes inhabiting the biotopes each locality-specific section also includes information regarding water chemistry, flora, insects, reptiles, mammals and birds to be found at the various localities.

Production quality is high with lavish colour photography throughout, including some memorable underwater images, and overall these books represent an irresistible insight into some of the most beautiful freshwater habitats in the world.

A total of 163 endemic freshwater fish species are known from Mexico and some of them are highly-endangered. In order to assist around 20 % of the cover price of each book is donated to the Fish Ark Project based at the Aqualab, Universidad Michoacána, Morelia.

The Aqualab maintains a number of species in danger of extinction or which are already extinct in the wild, including goodeids and other livebearers, so by buying these books you’re also supporting a worthy cause!

Not only that, SF readers can get a 10% discount by ordering the books from www.freshwater-biotopes.org and entering the discount code ‘SF10‘.

The offer is only valid for a limited period and the first book is now back in stock after the first print run sold out (and at a lower price than before too) so we advise getting in there quickly to avoid missing out this time!

Have you seen Xenoophorus captivus?

This is an appeal on behalf of the Goodeid Working Group (GWG) who are searching for anyone maintaining the critically-endangered species Xenoophorus captivus.

The majority of goodeid species are threatened with most having declined since the late 1990s and X. captivus has long been suffering from habitat loss due to pumping of groundwater and diversion of natural springs for irrigation and drinking water.

It was originally known from seven localities in three geographically-disparate areas in the states of San Luis Potosí and Zacatecas, Mexico, some of which are located in endorheic drainage basins with the others forming part of the upper Pánuco River, but by 2003 three of them had already disappeared.

Recent news received from Mexican aquarist and naturalist Juan Miguel Artigas Azas paints a depressing picture of the current situation, as he had been unable to find the species at its type locality, the Río Santa Maria, or any of the upper Pánuco localities with the habitats completely dessicated and unable to support fish of any kind.

Worse, this species is very rare in the aquarium hobby, so the GWG has launched an urgent appeal to try and find any remaining populations being maintained in captivity.

If you keep, or know someone who keeps, this species, especially fish of the ‘Moctezuma’, ‘Venados’ and ‘Agua de Enmedio’ populations, please get in touch with the GWG via their website and you may be able to help preserve it.

The GWG is a non-profitable international working group formed in 2009 in response to the critical environmental issues facing the majority of wild goodeid species and the poorly-documented ‘disappearance’ of many captive collections.

Keep an eye on the site as we’ll be featuring the group’s work in greater detail shortly.
