Jezero Palić je hipertrofično jezero u severnoj Srbiji oko osam kilometara istočno od Subotice. U maju 2009. godine novi prečistač otpadnih voda Grada Subotice je pušten u pogon. Radom prečistača postignuto je smanjenje koncentracije nutrijenata od više od 90% a s time poboljšanje kvaliteta vode u jezeru Palić.
Ali postoji i negativna posledica ovog poboljšanje kvaliteta vode: Populacija invazivne vrste babuška (Carassius gibelio) se sada masovno razmnožava i ugrožava prirodni biodiverzitet u jezeru. U proleće 2016 populacija babuške dominira biomasom riba u jezeru Palić sa više od 90 %.
U martu i aprilu 2016. godine smo istraživali metode kako bi se smanjio pupulacija babuške bez ugrožavanja autohtone vrste. Kao najperspektivnije metode su se ispostavili ribolov sa strujom i velikom vrškom.
Lov na strujom dovodi do toga da se riba ošamuti ali ne povređuje ili ubija ribu. Sa velikim vrškama riba se hvate bez povrede. Sa oba ova načina sve autohtone vrste nisu bile povređene i bile su vraćene nazad u jezero.

Lake Palić is a hypertrophic lake in North Serbia about eight kilometres east of Subotica. In May 2009 the new wastewater sewage plant of Subotica was put into operation and a nutrient reduction of more than 90% and a huge improvement of the water quality in Lake Palić was achieved since then.
But there is a negative consequence of this water quality improvement: The population of the invasive species Prussian Carp or Gibel Carp (Carassius gibelio) is now massively increasing and endangering the natural biodiversity. In spring 2016 the fish biomass in Lake Palic was dominated by more than 90% by the Prussian Carp.
In March and April 2016 we were investigating methods how to reduce the Prussion Carp population without harming autochthonous species. The most promising methods are fishing with electricity and big trap nets (Trappnetz).
Electricity is only anaesthetising and not killing or injuring the fish. The trap nets catch the fish without harming them. With both methods all autochthonous species were not getting harmed and returned back to Lake Palic.
This investigation was guided by the German experts from Fischerei Dr. Kuhn GbR and financed by GIZ - Deutsche Gesellschaft für Internationale Zusammenarbeit.
