Given similar or equal inputs I suppose you would end up being almost equal.
I guess my question is about the minerals and vitamins and whether aquaponic vegetables would contain similar values to vegetables bought from a green grocer. This would be dependant on the fish feed I suppose? (Well for the mineral content as plants make the vitamins)
Buying a good quality fish food would then be very important.
Actually MacGyver, it is highly likely the food from AP will exceed the nutritional value of anything you can buy, even 'organic' food.

It would be overkill to say that the carrot you eat today has very little nutrition in it—especially compared to some of the other less healthy foods you likely also eat—but it is true that fruits and vegetables grown decades ago were much richer in vitamins and minerals than the varieties most of us get today. The main culprit in this disturbing nutritional trend is soil depletion: Modern intensive agricultural methods have stripped increasing amounts of nutrients from the soil in which the food we eat grows. Sadly, each successive generation of fast-growing, pest-resistant carrot is truly less good for you than the one before.
Another interesting datum is the isolated groups we have found that have many of their members living past 100yo. One of the very few common factors is all the remote people so far found with this ability to live so long and be healthy burn and rebury their organic wastes. Food scraps all get burned and then added back into the soil.
There are patches of ground in the Amazon jungle that are unusually fertile - jungle ground is not usually very good ground for growing things. But these patches, scattered all around and often remote from each other will grow plants faster and larger than another area right beside them.
It took a while to find out why - someone, and nobody knows who because even the natives in the area don't know, has been 'salting' the ground with organic charcoal. It is so effective in replacing all the trace elements and minerals that now, possibly thousands of years after the original people did this, the ground is still extremely fertile.
Almost none of the food we can get in shops has anywhere near the nutritional content of even 100 years back because almost nowhere in our society do we let the earth go fallow and recuperate. Instead we pump back in what we think of as the necessary constituents for a healthy plant and happily sacrifice good value nutrition for nice looking produce.
I think AP offers a chance to grow food with most if not all of the original nutritional value.
