Describe typical solutions in terms of fish populations. page 117) la lb 1g 1h 1c 1d le 1f ] Page#117problem is given below Introduction A fish population is growing in a lake according to the model: dP P (₁-²) - d dt b =aP 1 where P denotes the population in thousands of fish after t years from some initial time. This is logistic growth with carrying capacity b and inherent growth rate a. In addition there is fishing: d thousands of fish are being removed per year.
