This lesson incorporates clips from Blue The Film as learning inspiration. In this lesson students learn about sustainable fishing by exploring the reasons we should wait for fish to grow to certain sizes before we catch them. They learn about how science is involved in helping people to fish responsibly. Students take part in an activity that allows them to experience sorting and sizing fish, to work out if it is a good catch or a great catch. They then decide whether to keep the catch or return it to the sea. Finally the students discuss how they can help the fish of the oceans when they go next go fishing.
- learn about why and how we should fish in a way that doesn’t harm marine ecosystems.
- identify what a fish is and where it lives
- understand the difference between a juvenile and a mature fish
- conduct measurements using a ruler
- communicate ideas with others
- suggest ways we can all help fish.

Blue is a feature documentary film charting the drastic decline in the health of our oceans. With more than half of all marine life lost and the expansion of the industrialization of the seas, the film sets out the challenges we are facing and the opportunities for positive change. Blue changes the way we think about our liquid world and inspires the audience to action. Find out how to screen or download the film here. Along with the film is an ambitious global campaign to create advocacy and behaviour change through the #oceanguardian movement. To become an ocean guardian, see the website.
