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 |
