A delayed differential-algebraic biological economic system was formulated and the stability of its posi-tive equlibrium was investigated .By using the normal form approach and center manifold theory of the differential -alge-braic system , the Hopf bifurcation of the differential-algebraic biological economic system was discussed where the time delay was considered as a paramter of bifurcation .
