This special catch was also made by Máté Siket in early March of the previous year.

Nearly a year later, the same fisherman, Máté Siket, once again caught the peculiarly colored, red giant carp in the Ráckeve-Soroksár Danube.

The record holding fish of the Ráckeve-Soroksár Danube are equipped with chips, allowing the fish wardens to identify the specimen's previous data during certification.

At the time of weighing, it was revealed that the red carp had lost nearly 3 kilograms of weight since last year.

The fish weighed 24.2 kilograms a year ago, while this year it only weighed 21.5 kilograms. Another interesting detail is that the location of the catch this year was 2 kilometers upstream from last year's catch location.

Experts have previously stated that the carp's unique color is due to faulty genes. This variation of Cyprinus carpio has a body color except for its head that deviates from the usual colors.

"The pigment cells in its skin produce less black melanin and iridescent guanine, and more red erythrophil and yellow xanthophyll than usual. This is a developmental anomaly," they wrote.
