Integrated Multi-Trophic Aquaculture (IMTA) systems, incorporating carp and mussels, represent a promising approach to aquaculture that enhances environmental sustainability by promoting nutrient recycling and reducing ecological impact. The Ropșa carp was used in the experiment for its adaptability to variable environmental conditions and precocity, reaching sexual maturity at 2-3 years. Selective breeding and epigenetic programming allow fish with improved growth performance and efficient feed conversion, contributing to increased productivity and reduced environmental impact. After selection of the specimens that showed good adaptability to high temperature conditions and a critical concentration of dissolved oxygen in the water, their growth was carried out in eight cages, in polyculture (Ropșa carp and Sinanodonta woodiana mussels), and in the rest of the water body in the experimental pond the population was mixed (three summers aged fish of various species and S. woodiana mussels). At the end of the experiment, a good percentage of growth and survival in cages was obtained for both studied populations, with monthly recording of production data and testing of water quality parameters.
