The first results on interactions among diploid, gynogenic and triploid tench, Tinca tinca L. under communal testing

Popis výsledku v původním jazyce

Amphimictic diploid (2n), induced meiotic gynogenic (MeiG) and induced triploid (3n) siblings of tench, Tinca tinca L., were separately nursed, marked and kept in long-term communal testing in pond until sex maturation and natural spawning. Survival rates during the initial periods were lesser in 2n and 3n compared to MeiG population (65%). The first overwintering period showed decreased survival of 3n (62.67%) compared to MeiG (90.0%) and 2n populations (91.67%). Survival rates during the next seasonsranged in 70.50% - 90.97% similarly in both 3n and 2n while in MeiG population it dropped to 38.0%. Weight and length growth of all populations studied showed significantly higher growth of 3n females and of 3n in general, compared to 2n and MeiG populations (P<0.001). Health examinations found metacercaria of Diplosthomus spathaceum in eyes of 2-year-old 3n specimens, weak polyparasitic infections of skin and gills by Dactylogyrus, Trichodina, Thrichophrya, Apiosoma and Chilodonella spp
