If there were a Shire fishfarm...

I just came across this site with an idea for the aquaponic fish farm.

As far as the fishing part...

There was this one place close to where I lived back in Iowa called Lunker Land.  It was three small ponds.  In one pond they had catfish, in another pond they had bass and I believe they had trout in the third.  You'd go there, fish and you could keep whatever you caught and paid by the pound. 

I found this that might be helpful.

Catfish can be farmed in an incredibly small space. So long as the water is flowing (a recirculating system works fine), they do just fine packed gill-to-gill.

The problem in NH is that catfish don't thrive in lower temperatures. The average daily temp in NH is probably at the lower limits, and is certainly not optimal for growth. That means introducing heat to the system, which means adding overhead costs. Or, you could limit your farm to a basement-size operation.

Just about any fish farming in NH would depend on some source of heat during part of the year.

That's not what all the people actually doing are saying.

[Lloyd Danforth]

What are they raising? I know people raise Trout, but it takes a long time to get them to an edible size.

[Kat Kanning]

trout, bass, bluegill, catfish, bull head...websites were discussing the depth the ponds need to be to overwinter the fish in NH.

If ya raise them in ya bath tub, the probably do o-k.

Yeah, that second story I linked had a picture of your bathtub...

Ha!  That's an old pic, it's nicely tiled now.
And a swim up bar has been installed.
