WHAT IS AQUACULTURE?
The Future of Sustainable Seafood
The cultivation of aquatic organisms such as fish, shellfish, and seaweed in controlled environments.
WHY AQUACULTURE MATTERS.
- Provides over 50% of global seafood consumption
- Reduces pressure on wild fish stocks
- Can support food security and livelihoods
- Plays a role in climate-resilient food systems
TYPES OF AQUACULTURE
Salmon and Sea Fish
Raised in large open-net pens in coastal waters.
Grown on the seabed, in protective netting or bags
Or suspended above the sediment from rafts.
Grown on the seabed in protective netting or bags
Or suspended above the sediment from rafts.
Suspending long lines below the surface of marine waters, where it can grow naturally.
A hatchery that provides the right environmental conditions for the larvae to grow and develop, mimicking their natural habitat.
Shellfish
Seaweed
Crustaceans
Types of Aquacutlure Systems
Closed looped
Open looped
Water flows in and out of the system continuously. New water is constantly introduced (e.g., from a well, lake, or municipal source), and used water is discharged after minimal or moderate treatment.
Water is reused within the system. It circulates through filtration and treatment units (biofilters, mechanical filters, UV sterilizers, etc.) before being returned to the tanks.

Question?
DRAW YOUR OWN AQUACULTURE ENVIRONMENT
Choose one of the categories from the previous page and draw an enclosure.
Think about how they will grow and how they will get nutrients.
WHAT IS REQUIRED:
1: An Enclosure
2: Food or Nutrients
3: A Stable Environment
This is where our aquaculture creatures will live and reproduce.
This environment will be carefully controlled and made observable for us to study.
Our organisms are going to be hungry, and we will regularly feed them to keep them growing healthy and strong.
We will need to ensure the water our organisms live in in temperate and rich with the nutrients they need to live.
This means testing for oxygen, ammonia, and nitrates.
Tank Setup & Cycling
Learn how to properly set up a freshwater aquarium, including the nitrogen cycle.
Now lets take part in raising fish and other aquatic animals in controlled, enclosed environments.
Students work in groups to set up small tanks, install filters and heaters, add substrate and decorations, and begin the cycling process using either fishless or seeded methods.
Include testing for ammonia, nitrites, and nitrates.
