It is free to download the books, but we will appreciate if you make a donation to the AquaLab at the University in Morelia, Mexico.

AquaLab performs a major and important work with endangered species, and we would like to support them by making our books available without any personal profit. All donations will go in full to the AquaLab.


It is entirely up to you and your conscience how much you want to donate to the AquaLab, but we recommend $ 20 for both books.

Your donation actually makes a difference, as AquaLab works with a limited buget.


Donations are only possible by using PayPal.


Start downloading by clicking the cover of the book you want to download.
