Item CALITATEA PRODUSELOR PISCICOLE ÎN RELAȚIE CU METALELE DIN MEDIUL ACVATIC ȘI PROCESELE DE ACUMULARE(CEP USM, 2024) Zubcov, Natalia; Zubcov, Elena; Ene, Antoaneta; Bagrin, Nina; Ciornea, VictorCurrently, the polyfunctional role of microelements in the metabolic processes of ichthyofauna (respiration, hematopoiesis, digestion, multiplication, increase or decrease of growth intensity resistance) is unanimously recognized, being also an indicator of the quality of fish products. The experimental investigations allowed the elaboration and implementation of the use of microelements-metals to increase the viability of fish in early ontogenesis, to increase the nutritional base in ponds, confirmed and protected by patents and which has essentially improved the technology of artificial fish breeding and served as an essential support in the development of fish farming. By using ICP-OES techniques for metals quantification, and tested regarding the impact of some metals and metalloids on the development of fish, their potential for the accumulation of metals, the concentrations of which are limited for fish products. It is also worth mentioning the redistribution of metals between different organs of fish in dependence on the intensity of growth and reproduction processes and fish health state. The highest concentrations of metals are recorded in the skin, liver and gills of fish.
