Nyn\u00ed je v\u0161ak situace jin\u00e1. Pot\u00e9, co se po sametov\u00e9 revoluci rekonstruovaly a odbah\u0148ovaly \u010desk\u00e9 rybn\u00edky, za\u010dal karas obecn\u00fd pomalu p\u0159ich\u00e1zet o sv\u00e9 p\u0159irozen\u00e9 prost\u0159ed\u00ed.

V\u011bdci pracuj\u00edc\u00ed v Hydrobiologick\u00e9m \u00fastavu Akademie v\u011bd se v\u0161ak situaci rozhodli zm\u011bnit.

Pomoci s mapov\u00e1n\u00edm v\u00fdskytu karase obecn\u00e9ho tak m\u016f\u017eete i vy. Ale pozor, oba druhy t\u00e9to ryby si spousta lid\u00ed velmi \u010dasto plete.
