Vimba vimba Spawning conditions Mating system The spawners gathered in the spawing site form groups consisting of several individuals, one female being always accompanied by a few males […] The spawning as a rule is very boisterous, accompanied by the water splash, vigorous swimming and movements of fishes Promiscuity
Vimba vimba Spawning conditions Nycthemeral period of oviposition The spawning itself begins most often in the early morning Day
Vimba vimba Spawning conditions Spawning substrate Deposit eggs on stony and gravel beds Lithophils
Vimba vimba Spawning conditions Spawning temperature The spawning itself begins most often in the early morning, when the water temperature is 16-18°C 17.0 °C
Vimba vimba Spawning conditions Spawning water type For the spawning purposes the vimbs enter streams with clear water and fast current Flowing or turbulent water
Vimba vimba Egg Egg adhesiveness Owing to their viscosity, become attached to the substrate Non-Adhesive
Vimba vimba Female Relative fecundity The individual fecundity of the investigated Rega vimbs of the body lengths ranging within 25.0-38.0 cm amounts to 33800-139000 eggs (the mean value 77500), while its relative fecundity ranges from 81000 to 159000 eggs per 1 kg of fish (the mean value is 114600) [...] Other studies: With the body length range of 25.0-38.0 cm to vary from 40000 to 100000 eggs, the mean value being 66000 [...] Niemen vimbs within the range of 38000-130000 (the mean valu 73,600) 31.5 thousand eggs/kg
Vimba vimba Female Age at sexual maturity The fourth age group almost exclusively comprised males, females being rarely encoutered. This indicates that males reach the maturity state in their fourth year of life, i.e., a year earlizer than females No data
Vimba vimba Spawning conditions Spawning migration distance While migrating from the sea to the Trzebiatow spawning ground, the vimbs cover the distance of about 20 km 20.0 km
Vimba vimba Egg Egg Buoyancy Fertilized eggs drifting with the current fall upon the stony - gravel bottom Ambiguous
Vimba vimba Spawning conditions Spawning migration period The vimb spring migration is held in spring (April-May), a month before the spawning itself ['April', 'May', 'June']
Vimba vimba Female Absolute fecundity The individual fecundity of the investigated Rega vimbs of the body lengths ranging within 25.0-38.0 cm amounts to 33800-139000 eggs (the mean value 77500), while its relative fecundity ranges from 81000 to 159000 eggs per 1 kg of fish (the mean value is 114600) [...] Other studies: With the body length range of 25.0-38.0 cm to vary from 40000 to 100000 eggs, the mean value being 66000 [...] Niemen vimbs within the range of 38000-130000 (the mean valu 73,600) 31.5 thousand eggs
Vimba vimba Spawning conditions Spawning season The vimb breeding in Rega usually takes place in late May or in the beginning of June ['May', 'June']
