take for all the fish to die? Suppose that a fish population P(t) in a lake is attacked by a disease at time t=0, witht the results that the fish cease to reproduce (so the birth rate beta=0) and the death rate( d, deaths per week per fish) is thereafter proportional to 1/sqrt(P). If there was 900 fish in the lake and 441 were left after 6 weeks, how long did i take all the fish in the lake to die?
