The article highlights the unique characteristics of 'Balaton fish,' particularly the perch and carp, farmed in the Balaton catchment area since the 1920s. It notes the special quality of perch meat, which is snow-white, lean, fibrous, and tender, attributed to the rich diet of native white-fleshed fish in the catchment area. For carp to carry the 'Balaton fish' geographical indication, it must be from the 'Balaton sudár' or 'Varászló mirror' species, reared in the Balaton catchment area. The carp meat is known for its compact and elastic texture, resulting from a high-protein diet and supplementary shellfish feed.
