| Description | The aim of the study was to analyse the selected immune and physiological parameters in diploids and triploids of C. a. gibelio, triploids of C. a. langsdorfii as well as the hybrids between C. a. gibelio and C. carassius and hybrids between C. a. gibelio and C. carpio. Following physiological and immune parameters were analysed: differential leukocyte counts, erythrocyte count, spleen size, luminescence analysis of oxidative burst, bacteriolytic activity of complement system, lysozyme concentration in skin mucus, condition factor, gonad size and gonado-somatic index. The erythrocyte count decreased significantly with increasing ploidy level. The highest lysozyme concentration in skin mucus was found in diploids of C. a. gibelio comparing to C. a. langsdorfii and hybrids. The luminescence analysis of oxidative burst revealed the highest values in diploids of C. a gibelio and hybrids C. a. gibelio and C. carassius. Concerning to bacteriolytic activity of complement system the highest activity was found in both diploids and triploids of C. a. gibelio. The smallest values of bacteriolytic activity of complement system was found in C. a. langsdorfii. The preliminary analyses suggest that the imunity of C. a. gibelio is weakened compared to triploids of C. a. gibelio and C. a. langsdorfii and interspecies hybrids of C. a. gibelio. |
