Species Development state Trait Primary Data Secondary Data
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 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 Female Age at sexual maturity Attain sexual maturity at 3-4 years of age Sex not specified] 3.5 years
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 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 Mutliple
