In an atlantic fishery, anchovies are extracted at a constant rate of 6000 anchovies per year. The per-capita death rate by other causes is 0.35 anchovies per year and the per-capita birth rate is 0.60 anchovies per year.
i) Derive a difference equation to describe the anchovie population.
ii) Solve this difference equation and determine the steady state. Is it stable or unstable.
Having problems with deriving an equation, I should be abe to solve it and determine it's steady state if I have an equation.
