Abstract
We introduce a linear model for age structured populations which migra te between several locations or patches. Birth is allowed in each patc h. Existence, uniqueness and positivity of solutions is proved. A cert ain North Atlantic fishery is given as an example. Asymptotic solution s are characterized in a general system with periodic coefficients by spectral theory techniques and the results are applied to the example.
