Discover how aquaponics systems work, and how they can create much more yield than traditional forms of cultivation. Learn everything you need to know to establish an aquaponics system on your permaculture property. Select the most suitable fish and plant species for a vibrant, high-yielding system. Explore the ways of providing for the needs of your system from your site.
This course offers a comprehensive guide to setting up an aquaponics system on your permaculture property – so you can raise fish and grow plants in a system of cultivation that has low energy inputs and high yields.
Then the course explores the main types of modern system in use today, which are:
• The nutrient film technique
• The deep-water culture technique
• The media bed technique
Setting up your own media bed aquaponics system is relatively easy – and once it is in place, it is a very efficient mode of food productions. In this course you will learn the essential bits of equipment you need to create a complete system, and you get advice on suitable sizes and materials for the various components, such as the fish tank, the container for the growing medium, the pumps to circulate the ater, and an aeration pump to provide oxygen to the organisms that inhabit the system.
One of the key organisms is the bacterium that cycle nitrogen through the system.You will also learn how to ensure suitable water conditions in your tank not only for the bacteria to flourish, but also for your fish to feel comfortable.
Choosing a species of fish for your system is another important decision. This course gives you the lowdown on some of the more common species that are able to thrive in aquaponics systems, including:
We’ll also look at the role manufactured fish pellets can play in meeting the dietary needs of your fish stock.
Such a food source can often provide necessary minerals and trace elements that may be lacking from other sources, but you’ll learn what to look for when sourcing pellets, and how your buying choices can have impacts on wider wild ecosystems.
From there, we’ll move on to discussing one of the main yields for the permaculture gardener from an aquaponics system – the crops. We’ll look at the kinds of species of fruit, vegetable, and herb that do well in any system, regardless of size, as well as others that need slightly higher nutrition levels, but which can still easily be cultivated in a home aquaponics system.
You’ll learn how to plant your specimens into the media bed so that they get the best chance of establishing themselves, as well as some tips for ensuring a flourishing system over time – including ways to provide them with essential nutrients they need which may not be available from the system itself.
One of these ways is to incorporate worms into the media bed. Just as with traditional soil-based garden beds, worms can bring many benefits, from processing nutrients in the water into a form that allows plant roots to access them to keeping soil pests and pathogens at bay.
