Species | Development state | Trait | Primary Data | Secondary Data |
Tinca tinca | Female | Absolute fecundity | Mean batch fecundity for control ranged from 38.7 to 54.4 in three different years, and cumulative fecundity from 144.5 to 217.8 | 38.7 thousand eggs |
Tinca tinca | Male | Age at sexual maturity | Attain sexual maturity at 3-4 years of age Sex not specified] | 3.5 years |
Tinca tinca | Spawning conditions | Spawning period duration | In Poland, during the season 3-4 batches are depostited at about 2-week intervals between the second half of June and mid-August. In their experiment, the spawning period lasted between 32-66 days in the controls | 3.5 weeks |
Tinca tinca | Spawning conditions | Spawning temperature | Begin spawning when the water reaches 19-20. In their study, the lowest temperature releasing spawning was 19°C, and the highest temperature at spawning was 29°C, mean temperature in the controls between the three years ranged from 20.6 to 23.9°C | 19.5 °C |
Tinca tinca | Spawning conditions | Spawning release | Independent of climatic conditions, it depositis different numbers of batches during the spawning period: in Wes siberia 2-3 batches, in Lithuania and in the Kijowski dam reservoir, 3 batches; in the danube estuary 3-4 batches and in the Dniepr basin 4-5 batches | Multiple |
