Apart from the aspect that I consider this design to be flawed, I can give you some rough estimates on yield.
A sound stocking density for tilapia would be around 50-60 kg/m3. If you keep temperatures high (28-30°C) you can have two harvests in one year. Tilapia has approximately 40% filet, so you can produce roundabout 50kg of edible fish fillet in one cubic meter fish tank.
With such a fish tank you can approximately produce nutrients for ten square meters of grow beds. A realistic estimate for the yield would be 10kg of produce per square meter per year, maybe a little higher if you take good care of the system. So that would give you 100-150 kg of produce per year with a 16sqm green house, a one cubic meter fish tank and ten sqm grow beds.
The recommended consumption of produce is 100-150 kg per year. So your system could cover your produce consumption for one person.
You still need carbohydrates (grains) and oil (rape seeds and sun flower and such) and protein. The fish will not cover your protein demand.
You'll also have to keep in mind that depending on how you run the system you'll have a lot of fish twice a year. Staggered production is not possible in one smallish fish tank.
