Abstract
The aim of the project is to develop the freely accessible electronic version of the book entitled Fish fauna of Hungary by Ákos Harka and Zoltán Sallai, published by Nimfea Environmental and Nature Conservation Association in 2004. This illustrated identification and distribution area guide summarizes 25 years of research and field experience, filling a critical gap in several accredited (BSc and MSc) departments of the field of natural sciences as well as agricultural sciences. The electronic formats (HTML, PDF and PS) resulting from the project would complete the description of 90 fish species, 21 figures, 90 distribution maps and 100 colorful photos with internal links and external links enabling a better understanding of habitats and nature conservation aspects, and contributing to the more efficient use of the book in higher education.
