Erythrocyte Micronuclei and Nuclear Abnormalities in Three Species of Fish from Lake Piediluco (Central Italy)
The frequencies of both micronuclei (Mn) and nuclear abnormalities (NAs) were determined in peripheral blood smears of European perch (<i>Perca fluviatilis)</i>, rudd (<i>Scardinius erythrophthalmus)</i>, and pikes (genus <i>Esox</i>) from Lake Piediluco (Central...

| description | The frequencies of both micronuclei (Mn) and nuclear abnormalities (NAs) were determined in peripheral blood smears of European perch (<i>Perca fluviatilis)</i>, rudd (<i>Scardinius erythrophthalmus)</i>, and pikes (genus <i>Esox</i>) from Lake Piediluco (Central Italy). Given the conformation of the lake, all the animals from the three species were equally exposed to the same natural stressors. To assess the different stress responses in the three species, 20 blood smears per specimen from each species were analyzed, counting the micronuclei and nuclear aberration present over a total of 1000 erythrocytes for each slide. Different responses to stress were recorded in the three species, with <i>P. fluviatilis</i> exhibiting the least amount of both Mn (0.42%) and NAs (0.01%), and therefore the better homeostasis, while the majority of Mn and NAs were recorded in <i>Esox</i> spp. (Mn: 3.88%; NAs: 23.18%). No MN were observed in <i>S. erythrophthalmus, so</i> that might not be an adequate species to apply the micronucleus test, and it also presented a lower percentage of NAs (15.32%) compared to the pike samples. This work provides, for the first time, baseline values of erythrocyte micronuclei and nuclear aberration from natural populations of the three fish species in a lake from Central Italy. |
