文摘

A stage-structured bio-economic model with stochastic fluctuation and the harvest effort is established by differential-algebraic equations.

The model is simplified by stochastic averaging method.

Stability of equilibria and bifurcations are presented.

The possibilities and the positions of the Hopf bifurcation will be change with stochastic fluctuations.
