Topic outline

This course explores how to assist migratory fish populations impacted by irrigation infrastructure.

The course details migratory fish ecology and how river development such as dams and weirs impact fish, biodiversity and food security.

It also looks at practical solutions to modernize irrigation through policy and engineering tools that can mitigate the impacts of river development on fish populations.


This course is intended for:

  • Field-level programme officers and technical advisors in the water, food and agriculture sector.
  • Academics and researchers with an interest in irrigation and fisheries.
  • Policy advisors and donors.

  • Describe migratory fish ecology by exploring how and why freshwater fish migrate.
  • Recognize the types of irrigation infrastructure barriers and how they influence fish migration.
  • Explain the different solutions that can be applied to overcome fish migration barriers.

This course consists of three lessons of approximately 35-60 minutes duration each:

  • Lesson 1 - Migratory fish ecology
  • Lesson 2 - Barriers to fish migration
  • Lesson 3 - Mitigating fish migration barriers
