Hello from Southern Central Michigan, USA

[matwalk]

I want to raise fish and grow produce. My neibor wants me to raise a few coy for his pond.
I have (4) 275 gallon tanks and (5) 55 gallon tanks all are food grade. Where do I start.
My interests are fishing , hunting, berry picking and organic gardening. Oh I also do alot of cooking and baking. I work inthe the auto industry in the welding field. I am thankful for any advice.

sounds like a great start to a system!
start with the basics, simplest system would be 1gal growbed to 1 gal ft, from what i have found 2:1 is closer to ideal, for that you'd need a sump..
maybe a couple of the tanks for fish, and 1 for a sump (are these regular glass tanks, or the ibc tank totes? - these can be cut down for growbeds as well)

for every 100gallons of growbed, expect about 25 lbs of "grown out" fish on a newer system (first year)

so much info, so little time
best of luck, and post pic's of your system when you start building (and ask lots of questions)
