The Center for Genotyping of Fisheries Resources was established in 2011, with the purpose of genotyping fisheries resources and determining the molecular diversity of fishery, evolutionary and ecosystem-significant fish species, in order to optimize management measures and preserve particularly important evolutionary and conservation units.

The basis of the work was the determination of the autochthonous status of the brown trout Salmo trutta population. The center consists of Predrag Simonović, Vera Nikolić, Ana Marić, Dubravka Škraba Jurlina, Tamara Kanjuh and Vojislav Sokolović.

In addition to institutional funding, the center's work is largely financed by its own revenues from the development of fisheries management programs and the genotyping of parent stocks. At the end of 2012, the first restriction fragment length polymorphism (RFLP) analysis was performed, and in the fall of 2013, the first of four new brown trout haplotypes was discovered.

Since 2023, the study of the diversity of the goby Cottus gobio and, for the first time, the diversity of the rainbow trout Oncorhynchus mykiss fund in Serbian aquaculture has begun. The center's research was conducted in collaboration with colleagues from the University of Montenegro (Danilo Mrdak), the University of Bihać (Azra Bakrac), the University of "St. Cyril and Methodius" in Skopje (Milica Ristovska) and the University of Zagreb (Marina Piria).

The discovery of the introgression of allochthonous brown trout into the gene pools of autochthonous ones has explained their population-genetic regulation mechanisms. Three doctoral dissertations and three master's theses have been completed at the center, and several more are in preparation. The results have been published in 23 papers and 16 presentations at scientific conferences.
