Abstract
The paper deals with the description of multispecies model
with delayed dependence on the size of population. It is based on the
Gurtin and MacCamy model. The existence and uniqueness of the solution
for the new problem of populations dynamics are proved, as well
as the asymptotical stability of the equilibrium age distribution.
