Trzebiatowski R., Narożański A., 1973. A contribution to studies on the biology of vimb - Vimba vimba vimba (L.) from the Rega River. Acta Ichthyol. Piscat. 3 (2): 17-27.
Some biological features of the spawning stock of vimb Vimba vimba vimba (L.) reproducing in the Rega River are discussed in the present paper. The investigated material comprising 845 individuals was collected within the years 1970-1972 from the spawning ground situated near Trzebiatów. The age analysis of the stock revealed that 8 years old fishes prevailed in 1970 and 1971, while in 1972 5 years old ones were predominating. The Rega vimb growth rate is higher than that of the fishes from the other water bodies. Particularly high growth rate has been noted for the first 7 years of life. Some symptoms of the stock rejuvenation occurred within, the period investigated.
