Sažetak
The frequencies of erythrocytic nuclear abnormalities (ENA), micronuclei (MN), vacuolated nuclei (VN) including cytoplasmic vacuoles (CV) were monitored in the peripheral blood of cultured shade fish Argyrosomus regius (Asso, 1801). Sampling was performed through three seasons: at the end of the winter (March), spring (May) and summer (July) at one location from southern Adriatic Sea (Croatia). ENA comprised blebbed, lobed and notched nuclei, which were the most frequent features, while the MN, VN and CV appeared sporadically. The highest level of ENA and MN were detected in July, and VN in March, respectively. The rarest appearance of these parameteres were recorded in May. Inversely, cytoplasmic vacuoles were the most frequent in May and the least in July. The Spearman rank order correlation test revealed a significant positive correlation between the frequencies of ENA and MN (P < 0.05, r = 0.44), ENA and VN (P < 0.05, r = 0.56). Also, the frequency of MN significantly positively correlated with water temperature (P < 0.05, r = 0.42) and negatively with level of oxygen (P < 0.05, r = - 0.42). Cytoplasmic vacuoles did not correlate with any measured parameters. Our results demonstrate that these parameters displayed a distinct seasonal variation.
