The story

At Bracken Waters, Leena shows Dougal and Zara a glass case holding a small model algae tank and a sealed jar of green powder, with covered tanks behind a gate.

At Bracken Waters, Leena showed Dougal and Zara a model of an algae tank and a sealed jar of tiny green powder.

At the distillery, Zara points from a sealed jar of grain to a picture of a fish feed packet, with Leena beside her and Dougal listening.

At the distillery, Zara pointed from the jar of grain to a picture of a fish feed packet. “How can grain help make fish food?” she asked.

Leena uses a pointer on three pictures in a glass display: a grain container, a closed algae tank and a small packet of dried ingredient, while Dougal watches.

Leena pointed to three pictures. Suitable grain goes into special closed tanks, tiny algae grow there, and they become a small dried ingredient.

For grown-ups: A suitable co-product that has been set aside goes into controlled specialist algae growing, which produces a tested, processed omega-3 ingredient for fish feed made up by professionals. The models and jars are illustrations, not a recipe or something to try at home.

Leena holds a small sealed jar of algae powder beside a picture of a fish feed pellet surrounded by pictures of three other ingredients, while Zara looks closely.

Leena held up the small jar beside a picture of a feed pellet. The algae ingredient was only one part, along with other ingredients.

Leena: “Tiny algae can make a useful ingredient. The fish still need a properly balanced diet.”

At the distillery board, Dougal pairs one grain card with one algae tank picture, while Leena and Zara look on and two other cards sit apart by feed store and boiler pictures.

Dougal put one grain card with the algae tank picture. The other batches stayed apart, ready for their own jobs.

For grown-ups: This batch for algae is its own allocation. The other cards are different batches, not the same material counted again for feed or heat.

Leena, Zara and Dougal stand at a display with one small sealed ingredient jar under a framed picture of a feed pellet and other small ingredients.

Back at Bracken Waters, they looked at the small jar under the picture of the feed pellet. One useful ingredient, one part of a balanced meal.

For grown-ups: Specialist omega-3 ingredient for professionally formulated aquaculture feed, not a complete diet.

The real-life bit

Specialist companies grow algae in controlled conditions, using a suitable co-product, to make a processed omega-3 ingredient for fish feed. It is one part of a professionally formulated diet, not a complete meal, and the sealed jars and models in the story are only illustrations. Gullbrae is made up. Your council’s own rules are the ones to follow.
