Description
  • Diploidní (2n), gynogenetičtí (MeiG) a triploidní (3n) líni Tinca tinca byly označeni a drženi v rybníce do pohlavní zralosti a přitozeného výtěru. Přežití v počátečním období bylo nižší u 2n a 3n ve srovnání s populací MeiG. První zimování ukázalo snížené přežití u 3n (62,67%) ve srovnání s MeiG (90,0%) a 2n populací (91,67%). Přežití v následující sezóně se pohybovalo v rozmetí 70,50-90,97% u 3n a 2n, u MeiG kleslo na 38%. Sledování délkového a hmotnostního růstu všech populací ukázalo signifikatně vyšší růst 3N samic a 3n obecně ve srovnání s 2n a MeiG populacemi (P<0,001). Při vyšetření zdravotního stavu byly nalezeny metacerkárie Diplosthomum spathaceum u dvouletých 3n línů, polyparazitická infekce kůže a žaber parazity Dactylogyrus, Trichodina, Trichophrya, Apiosoma a Chilodonella u 3n a 2n ryb, ale středně silná až silná infekce 100% jedinců byla zjištěna u MeiG populace. Analýza ploidie ukázala 100% diploidů ze spontánního výtěru s indikací řady kombinací. (cs)
  • 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 seasons ranged in 70.50#90.97% similarly in both 3n and 2n while in MeiG population it dropped to 38%. 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. in 3n and 2n s
