world freshwater fish atlas

[kiwidu21]

Good morning,
to pass my breeding in professional, I must constitute a file with files for each kind of fish which I wish to maintain / raise (it is obligatory in France). So I'm looking for a reference book, a world atlas with as many species as possible.
I already have several books on catfish (including Atlas of freshwater and marine catfishes) that can be used as a reference.
However, I only have mergus atlases for other fish.

Do you have a good atlas to recommend? Ideally, I should have only one reference, so a book that brings together the atlas on catfishes but also on other fish.
Does it exist?
If it's not a single book, maybe a particular collection?

A book of all sweet water fishes in the world would be too much to ask for. I have the book about sweet water fishes of Mexico - not much catdfish - but this one book is ome 300 pages. Large pages.

The book you would be after would be thousands of pages, a few kilos in total.

That's why I would rather think of a collection of books with several volumes, a bit like encyclopedias.
If really there is nothing like that, I will try to collect books but the problem will be at the level of the scientific names which have sometimes changed.

I'm not sure you can do better than the Mergus (Baensch) Atlases for being up-to-date and covering many fishes. The TFH atlas is getting even older looking and everything else of any size is even older again.
