  • Compute estimates of N0o and q from Leslie model regression results.
  • Four main assumptions of Leslie model and how do we try to make sure they are met.
  • What happens to q or N0 estimates from a Leslie model if mortality/recruitment exists.

  • Compute an age-length key from a two-way table.
  • Identify proportions and number of fish that will be assigned a certain age from an age-length key according to the Isermann-Knight method.
  • Describe how an age-length-key is used in the Isermann-Knight method.

You may have to research this fishery so that you can adequately describe several items in each aspect of the management environment.
