The aim of this study was to (1) determine complex interactions between macro- and micro-elements present in blood serum and ejaculate of common carp ( Cyprinus carpio ), and (2) examine the association between alterations in these macro- and micro-elements with markers of oxidative stress. Blood and ejaculate from 10 male carp were collected in the summer period on the experimental pond in Kolíňany (West Slovak Lowland). Reactive oxygen species (ROS), total antioxidant capacity (TAC), protein carbonyls (PC), and malondialdehyde (MDA) levels were measured in blood serum and ejaculate using spectrophotometric methods. The amounts of elements (Ag, Al, Ba, Co, Li, Mo, Ca, K, Na, and Mg) in all samples were quantified using inductively coupled plasma optical emission spectrophotometry. Data demonstrated significant differences in elemental concentrations between blood and ejaculate, specifically significantly higher ejaculate levels were detected for Ag, Al, Ba, Co, Li, Mo, K, and Mg. Potassium was the most abundant macro-element in the ejaculate, while sodium was the most abundant in blood serum. Among the micro-elements, Al was predominant in both types of samples. It is noteworthy that oxidative status markers including ROS, TAC, and MDA were significantly higher in ejaculate indicating the presence of oxidative stress in C. carpio reproductive tissue. The positive correlations between Mg and Ca in blood serum and ejaculate suggest these elements play a functional role in metabolic and physiological processes. In contrast, the positive correlations of Ba and Al with markers of oxidative stress indicated the association of these metals with induction of oxidative stress. Our findings provide insights into the association of metals with biomarkers of physiological function as well as adverse effects in C. carpio . |
