I believe most of all the equipment is on site but the %75 is what is done already but not knowing anything about it it is hard to tell. All the long tanks are in and plumbed the 4 big round fish tanks are in and plumbed. There are a bunch of pumps and valves in with all the piping. 2 - 200 Amp main panels are in I don't think the pumps are wired yet but I have done electric work for over 30 years so I would do that. There are many other tanks I am not sure what there function is. This is all built with commercial tanks no IBC totes. Here is a picture I copied off the real estate site. The tanks in the background I am not sure what they are for what you can't see is the 4 big fish tanks and another big tank burred near the fish tanks. There is a shop building full of more equipment to finish it.
I am not sure if the picture is view-able or not. My location is near a very large population within 20 miles of Portland, OR. I don't think selling the produce would be hard I am not sure what the demand is for farm raised fish since we have access to a lot of wild fish in the Pacific Northwest.
