In Dagestan waters, the most vimba enter the Terek, Sulak, samur rivers, and the Arakum waterbodies for spawning from April onward at water temperatres of 10-13°C/ mass-scale migration was recorded in the second half of May in water temperatures of 19-20°C ['April', 'March', 'May']
Vimba vimba Female Absolute fecundity In 1960, the fecundity of vimba in Kyzylagach bay was 8900-39600 eggs, average 27400 eggs. According to the data collected in 1963, the absolute fecundity of vimba of 13.5-20.5 cm varied from 8300 to 29200 eggs. The absolute fecundity of vimba from the Arakum waterbodies (central Caspian) was in the range of 7000-89200 eggs. The mean fecundity was: 25000 eggs in 1965, 23500 eggs in 1966, and 35200 eggs in 1967. Vimba in the Terek basin varied from 11900 to 65300 eggs. 24250.0 thousand eggs
