Tinca tinca Female Female sexual dimorphism Diploid females have soft pelvic fins, not reaching the anus Absent
Tinca tinca Female Maximum GSI value Most 7-10, but up to 17% [June] 8.5 percent
Tinca tinca Male Male sexual dimorphism Diploid males have longer pelvic fins than diploid females, with bulky first fin rays, and covering the anus in every case Absent
Tinca tinca Male Onset of spermatogenesis March-April [Secondary spermatogonia are then tranformed during April and May into primary spermatogocytes] ['April', 'March', 'May']
Tinca tinca Female Oogenesis duration The sum of temperature for the enitree oogenetic cylce calculated by summun day with mean daily temperature above 10°C ranged from 674 to 1047°C, or 1077 ± 24 1077.0 months

Tinca tinca Egg Degree-days for incubation 50-120, and 63.5 at 19-22 [From 90 at 18°C, 80 at 20°C and 35 at 25°C] 85.0 °C * day
Tinca tinca Egg Temperature for incubation Highest development rate was at 22.9, range 18.3-28.6°C tested 23.45 °C
Tinca tinca Female Resting period Between October and March No data
Tinca tinca Male Main spermatogenesis activity GSI increase from 0.5 to 1.6 in June ['June']
Tinca tinca Female Onset of oogenesis March [Vittellogenesis is slowly stimulated from mid-february to the end of April, by increasing temperature, but not exceeding 16-17°C] ['April', 'March']
Tinca tinca Female Intensifying oogenesis activity April-May [From 5 to 17%] ['April', 'May']
Tinca tinca Female Oocyte development Asynchronous type, ovary contains oocytes at all stages of development Asynchronous
Tinca tinca Egg Oocyte diameter 0.4-0.5 or 0.79 [Ova before hydration] 0.45 mm
Tinca tinca Male Spermatogenesis duration For spermatogonia divisions 700 degree days are needed and 1000 degree days for spermiogenesis 700.0 months

Tinca tinca Male Weight at sexual maturity 0.3 [Minimal body weight of male for optimal reproduction] 0.3 kg
Tinca tinca Female Age at sexual maturity 4-7 [Minimal age of female for optimal reproduction] 5.5 year
Tinca tinca Spawning conditions Spawning release In normal spawning pond, females deposited 3-4 eggs batches [39-54 000 eggs] during the season, and 5-8 batches in heated ponds, interval spawning was 15-22 days and first batch of eggs yielded 33-38% of total fecundity per season Ambiguous
