Hi

I'm looking to put together a business plan for a commercial system growing primarily trout.

I have found information saying that you can stock up to 1lb of trout per 3 us gallons (40kg of trout per m3), but haven't been able to discover how this translates to how much you can harvest.

I have seen information showing that trout can grow to marketable size in 13 weeks, which would equate to 4 harvests per year, but this seems optimistic to me.

If this was the case, it would seem that you could harvest 4lb (160kg) trout on average per 3 gallons (m3) of water each year which seems incredibly high.

Think I must have got something wrong somewhere!

Can somebody put me straight?
