Aquaponics is basically growing plants in fish water. So you need - fish -- water -- and plants.
This instructable only covers the fish and water.
- Catch a fish
- Get a bucket
- Fill with water
- Get a pump
- Put the pump in the water
For the whole system, the best book on the topic is by Sylvia Bernstein
Aquaponic Gardening: A Step-By-Step Guide to Raising Vegetables and Fish Together
- The fish were caught at a private club, normally fish this small would be thrown back.
- This includes some pictures of a dead fish -- 'fish-topsy'
Warning -- find better instructions -- 4 weeks latter I have 2 out of 6 fish remaining.
