I collected literature about some fish groups and since I know how difficult it often is to get knowledge about the existece of some papers, I list here group-specific bibliographies as they are known to me (and available elektronically - the major part of my literature is still in non-electronic catalogues). If you know about literature that you think should be included into the list, please send me a note.
For the beginning, you may choose betwen the fish groups:
Spined loaches (genera Cobitis, Sabanejewia and a little bit of related genera)
Mudminnows (genera Umbra, Novumbra, Dallia)
