Estimation of salmon species tiny fishes quantity and using of beaver ponds by them as fattening water bodies in spawning salmon waterways of the Republic Belarus
Abstract
It was ascertained that the density of bulltrout (salmon trout) tiny fishes made in the stream of Tartak from 37 to 70 individuals per 100 meters of watercourse, in the river Kimelina of 9-10 individuals, in the river of Dudka from 2 to 5, in the river Senkanka – 1-3 individuals. In terms of age in 2010 two year old fishes were predominating, 2011 – one year old fishes that apparently is attributed to low productivity of young fishes in 2010. Beaver ponds to some extent appear to be fattening water reservoirs for salmon tiny fishes mainly for the age of two and three years old, the density of tiny fishes in natural river bed is 2–7 times higher against the beaver ponds.
