Part 3: Use mizer models

Now that you have built your model, you can use it to explore the effects of changes in fishing and changes in the environment on the fish community and the fisheries yield. In this part of the course we will mostly use the old North Sea model that comes with mizer.

Tutorials

Using examples, the tutorials are designed to help you develop your own model simulation experiments:

  1. Run a simulation
    We take a detailed look at how the project() function works and the different ways in which effort and time can be set up.

  2. Explore the simulation results
    How can we explore the results of the simulation? In this tutorial we introduce a range of summaries, plots and indicators that can be easily produced using functions included in mizer.

  3. A simulation of the North Sea
    In this section we try to pull everything together with an extended example of a multispecies model for the North Sea

  4. Explore further scenarios
    This tutorial provides extra material, prepared by Julia Blanchard using another system (Patagonian toothfish fishery) as an example. Here you can learn on how to set time series of fishing changes and more.

Video overview

The following video by Julia Blanchard provides a broad overview of the different ways in which mizer is being used to help understand the consequences of change in aquatic ecosystems. There are a lot of ways!
