Researchers from the Balaton Limnological Institute, a native fish species believed to be extinct, crossed the lake into the lake on Thursday, the Ecological Research Center reported to MTI. According to the announcement, the reintroduction of the species to Lake Balaton in 2015 was not in vain, as István Czeglédi Y Bálint Preiszner, the Conservation Ecology and Fisheries Group of the Center for Ecological Research caught two healthy ling fish by monitoring the fish population.
Lake Balaton’s native fish species has become significantly rarer in the lake since the middle of the last century, then has certainly become extinct, presumably the main reason for the large eel planted at the time, which is an effective predator of larch in similar habitats.
The summary recalls that from 2015, the cooperation of Balaton Fisheries Management Nonprofit Ltd. and the Fisheries Department of the University of Szent István started the resettlement of ling in the lake. However, so far no specimens have been detected during monitoring and the species has only appeared in the Lake Balaton Fisherman’s Dam only a few times since resettlement.
The specimens captured by the researchers were between 25 and 30 centimeters in size and were returned to the water after photography. The strengthening of the population of Lake Balaton has yet to wait, until then fishing for the species is prohibited. However, the survey results prove the efficiency of stocking, which is another step in conserving Lake Balaton’s native fish population.
The larch (Lota lota) is the only freshwater representative of the cod in Hungary and is found in most of the Hungarian rivers. It was voted Fish of the Year 2013 in the Hungarian Haltology Society’s online vote.
