  1. 1-135-S-FishHarvesting

    08 Aug 2021 | | Contributor(s):: Jennifer Crodelle

    This modeling scenario will introduce students to the concept of a bifurcation through a fish harvesting model. This short activity will walk students through a guided list of questions to help them to understand how the stability of equilibrium changes with changes in a model parameter, in this...

  2. 1-127-S-FishHarvesting-StudentVersion

    06 May 2020 | | Contributor(s):: Will Mitchell

    We offer students a harvesting model for operating a fishery over a 25 year horizon and ask them to write a report on optimal harvesting policy with their analyses for fishing industry experts (not necessarily mathematicians).
