Intensive Aquaculture is where the animals or plants are contained in some way for ease of feeding, handing and harvesting. These systems vary from the flow-through types of system like cages in pond or the sea to the fully enclosed recirculating systems where the water is cleaned, aerated and purified each time it goes round the system.
Hobby means an activity you carry out for relaxation and enjoyment - even the taxman does not tax the benefits of a hobby - so long as the activity remains a hobby - a not-for-profit activity.
A pilot scheme is a small version of your full scale aquaculture venture and is in the nature of a proving trial to test the assumptions you have made in your major plan.
Some technical terms, conversion tables, maths and concepts that are handy to know about. Also includes more detailed technical and practical advice on how to start your system.
