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 Female Age at sexual maturity 4-7 [Minimal age of female for optimal reproduction] 5.5 year
Tinca tinca Female Weight at sexual maturity 0.4 [Minimal body weight of female for optimal reproduction] 0.4 kg
Tinca tinca Female Female sexual dimorphism Diploid females have soft pelvic fins, not reaching the anus Absent
Tinca tinca Female Relative fecundity 140-230, also 250-400, or 85.7-543.9 185.0 thousand eggs/kg
Tinca tinca Female Absolute fecundity 30-700 for females of 15-40 cm 365.0 thousand eggs
Tinca tinca Female Oocyte development Asynchronous type, ovary contains oocytes at all stages of development Asynchronous
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] ['March', 'April']
Tinca tinca Female Intensifying oogenesis activity April-May [From 5 to 17%] ['April', 'May']
Tinca tinca Female Maximum GSI value Most 7-10, but up to 17% [June] 8.5 percent
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 Female Resting period Between October and March 3.0 months
Tinca tinca Female Resting period About 4 [October to March] 4.0 months
Tinca tinca Male Age at sexual maturity 3-7 [Minimal age of male for optimal reproduction] 5.0 years
Tinca tinca Male Weight at sexual maturity 0.3 [Minimal body weight of male for optimal reproduction] 0.3 kg
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] ['March', 'April', 'May']
Tinca tinca Male Main spermatogenesis activity GSI increase from 0.5 to 1.6 in June ['June']
Tinca tinca Male Maximum GSI value 1.6 [June] 1.6 percent
Tinca tinca Male Spermatogenesis duration For spermatogonia divisions 700 degree days are needed and 1000 degree days for spermiogenesis 700.0 months
Tinca tinca Spawning conditions Spawning season Begins in May untill end of July ['May', 'July']
Tinca tinca Spawning conditions Spawning period duration 6-9 weeks at 22-25 7.5 weeks
Tinca tinca Spawning conditions Spawning temperature Generally spawning starts at 19-20 19.5 °C
Tinca tinca Spawning conditions Spawning temperature Optimal temperature is 22-24°C, at lower (19-20) and higher (25-29) temperatures fish begin spawning somewhat lazily and in small groups 23.0 °C
Tinca tinca Spawning conditions Spawning water type Deep parts of littoral zone in lake or dam reservoir [Stays at the same place during the spawning season at about 25 m from a spawning place] Stagnant water
Tinca tinca Spawning conditions Spawning depth At depth of 0.5-3 m 1.75 m
Tinca tinca Spawning conditions Spawning substrate Vegetation Phytophils
Tinca tinca Spawning conditions Mating system Spawns start in large groups with minimum of 10 individuals Promiscuity
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 Total
