Leuciscus idus Spawning conditions Spawning substrate Eggs are deposited on submerged plants, as well as roots, trunks, and branches of fallen trees, but they can be laid on stones, gravel, sand, and a muddy bottom. Thus classified as an indifferent lithophytophilous Ambiguous
Leuciscus idus Spawning conditions Spawning temperature Spawning begins when water temperature increases up to 5.5°C. During spawning mean temperatures of water are 6-10°C, extreme temperatures are 3 and 15°C. 8.0 °C
Leuciscus idus Spawning conditions Spawning period duration Spanwing is short, 2-5 days at 8-12°C. At lower temperatures may last two weeks, during cold springs spawning duration may be prolonged to> one month 3.5 weeks
Leuciscus idus Spawning conditions Spawning water type Ide spawn in rivers, streams, old arms, lakes, dam reservoirs, and meadows covered with flood waters. Stagnant water
Leuciscus idus Female Maximum GSI value GSI of mature females just before spawning (March-April) ranges from 7 to 20%, typically about 12%. In Scandinavian populations GSI value are higher, from 17 to 30% (mean 21%) 7.0 percent
Leuciscus idus Male Male sexual dimorphism Yellowish or white breeding tubercles apear in males during the spawning on the anterior part of the head Absent
Leuciscus idus Egg Incubation time In constant temperatures at 7°C incubation lasts 27 days, at 22°C only 5 days. In other studies: 5.5-23 days [At 9.3-13.8°C], 17 days [At 10-12°C], 24 days [At 3-12°C], 11-12 days [At 9.5-15°C], 22 days [At 10.5-17°C], 24-30 days [At 9.2°C] and 9-10 days [10-20.5°C] 14.25 days
Leuciscus idus Female Relative fecundity 84 eggs per g of body weight of female 84.0 thousand eggs/kg
Leuciscus idus Male Maximum GSI value In March-April, the mass of testes accounts for only 1.8% of body weight 1.8 percent
Leuciscus idus Female Age at sexual maturity As a rule, male mature one year earlier than females. In southern and central Europe, first spawning-ide are age 3-5 years, sometimes they are 2 years old. In eastern Europe, reproductive period begins at the age of 4 and 5 years. More precisely 6 years [Kävlingean], 4 years [Dniepr], (3) 4 [Dunaj] 4.0 years
Leuciscus idus Egg Degree-days for incubation 180-200 190.0 °C * day
Leuciscus idus Egg Temperature for incubation Temperatures < 6 and > 22°C are lethal for developping embryos, optimum temperatures are 13.5-17°C at which survival ranges from 79-84% 15.25 °C
Leuciscus idus Male Main spermatogenesis activity In November, the colour of testes changes from red to whitish, which is indicative of the presence of spermatozoans ['November']
Leuciscus idus Spawning conditions Spawning migration distance Maximally 2.5 km 2.5 km
Leuciscus idus Female Onset of oogenesis Ovaries start developing in June ['June']
Leuciscus idus Egg Egg size after water-hardening Swelling increases size of ide eggs from 1.2-1.6 mm to 2.1-2.3 mm 1.4 mm
Leuciscus idus Spawning conditions Spawning migration period In early spring (beginning of April) ide migrate upstream to spawning grounds. Populations linving in brackish Baltic waters migrate in May-June to spawn in rivers or near-shore lakes ['April', 'May', 'June']
Leuciscus idus Egg Oocyte diameter 1.2-1.6 mm [Unswollen egg] 1.4 mm
Leuciscus idus Female Absolute fecundity Ranges from 8731-263412, mean about 45000 to 88000 136071.5 thousand eggs
Leuciscus idus Spawning conditions Spawning season In southern and central Europe ide begin spawning in the second half of March or at the beginning of April. In nothern Europe and Siberia, spawning begins later - in the middle of May, or in June ['April', 'March', 'May', 'June']
Leuciscus idus Larvae Temperature during larval development Optimal temperature for larval development is about 17°C. Lethal temperatures are 23.7-29.1°C for ide larvae and juveniles. 26.4 °C
Leuciscus idus Larvae Reaction to light Larve are not photophobic Photopositive
Leuciscus idus Spawning conditions Homing It was observed that individuals spawn on the same places as in previous years. Thus, homing was reported for ide, similarly as for salmonid (and same other) fish Present
Leuciscus idus Female Weight at sexual maturity 523-760 g [In Sarvlax], 200-300 [In Dunaj], sex not specified 641.5 kg
Leuciscus idus Female Length at sexual maturity Standard length of females reaches 170-330 mm. More precisely 315-328 [Kävlingean], 190 [Dniepr], 281-306 [Dunaj] for females 250.0 cm
Leuciscus idus Male Length at sexual maturity Standard length of males reaches 180-310 mm. More precisely 220 [Dniepr], 278-310 [Dunaj] for males 245.0 cm
Leuciscus idus Larvae Initial larval size Total length of newly-hatched larvae is 5.5-8.7 mm (typically 7 mm). Larger larvae hatch from eggs incubated at higher temperatures, at 9°C : 6.6 (range 6.5-6.8) mm, at 13.4°C : 7.3 (range 6.3-7.5) mm, at 22°C : 7.4 (6.5-8.4) mm. Newly hatched larvae of ide are mode developmentally advanced compared to larvae of other cyprinid fishes 7.1 mm
Leuciscus idus Larvae Larvae behaviour Larvae have well developped cement glands with which they fix themselves to plants where their development occurs. Active swiimming in horizontal position begins 4 days after hatching. At that time their swim bladder is being filled with air Demersal
Leuciscus idus Male Weight at sexual maturity 523-760 g [In Sarvlax], 200-300 [In Dunaj], sex not specified 641.5 kg
Leuciscus idus Female Age at sexual maturity In southern and central Europe, first spawning-ide are age 3-5 years, sometimes they are 2 years old. In eastern Europe, reproductive period begins at the age of 4 and 5 years. More precisely 6 years [Kävlingean], 5 years [Dniepr], (3) 4 [Dunaj] 4.0 year
