​MEDFRI aims to develop selected lines of aquaculture species that are widely produced both in the institute and Turkey. Main features sought in the generic improvement programs will be fast growth and high resistance in the rearing conditions. Other target species in the improvement programs will be the ornamental fishes that are intensively marketed in Turkey. These will be made with an employment of both classical improvement methods and modern molecular approaches. Moreover, possible use of epigenetic factors will investigated in fish breeding programs and methods of production increments. ​
