Australia: Aquaculture and hydroponics in focus at Horticultural Training program at Werribee Park
The aquaponic system is set up in a glasshouse that combines aquaculture and hydroponics for students attending the on-site Horticultural Training program at Werribee Park.
Part of their studies is learning how to create a closed loop system to grow veggies, herbs and fish together. The trial project uses the waste produced by 12 goldfish to provide all the nutrients for the hydroponic herbs and vegetables.
The plants in turn purify the reticulated water.
Parks Victoria ranger and horticulturist Adam Smith, who runs the project, said this particular system used three types of hydroponic methods.
“Gravel growing beds, which act as a filter, gutter growing beds, which use pots, and floating beds where the plants virtually walk on water,” Mr Smith said.
“The students have been amazed as they watch the plants mature in about four weeks instead of nine in a veggie patch.
“No weeding is ever required and only recycled materials are being used in this system.”
The produce will go to both the park’s hotel restaurant and the students, and the goldfish will stay in the tanks for a couple more harvests, before being returned to the park’s pond.
In the future, edible species such as barramundi will be used.
Mr Smith said the aquaponic system was quick and efficient, with different crops planted about every four weeks.
