25. what to keep in mind before starting a farm?
Enough willingness to give up a secured life for an unsure future. The job of fish
farmer is interesting and the profits are usually good but working with life stock can be
also a risk.
Enough financial backing by own capital and/or bank, eventual subsidies must be an
extra never the foundation of a business.
To establish a farm you need, wherever in the world; building licences and
environmental licences.
Take care of energy sources and water sources.
Make a choice on the fish you want to farm in relation to your own feeling, the market
and the water source.
Take care of fingerlings, fry or eggs supply.
Try to make contacts and eventual contracts for the sales.
Find a good supplier of a fish farming system or fish farming elements.
Ask for references and try to make visits to an existing farm.

27. Water and Energy savings in RAS
• In a system - for example a pike perch farm or eel farm - without energy to
produce oxygen it shall be approximately 7 kW electrical energy per kilogram
produced fish.
• For Oxygen supplied by a generator we calculate 1 kW per kilogram
production.
• On average we calculate 1 kg Oxygen per kg production.
• When we install a system according the Bleu Label design we can run a
system on 50% of these costs.
• Additional installation of “free” energy sources like wind turbine and solar
panels will reduce the running cost and helps the environment.
• Re-use of filtered waste water will lower the use of additional fresh water
