Yammy, That pretty much sums it up. The question is not Can you grow them on land, but can you grow and make money on land. Salmon don't like being crammed into a tank. They respond by growing slower, so you don't gain. A lot of studies are based on running fish at densities in excess of 45 kgs of fish per cubic meter of tank volume. Problem is at this level, they grow slower and require more water flow. Looks good on paper, not so good in practise. I have alsways found that paper fish are easier to grow, especially if you have Excel.
Hey Holmes, what did you mean by inexperienced people at the hatchery in GR?
