Nutirents in Aquaculture System

Hello and thank you for a response,

I was wondering if anyone had some data on nutrients in the water after fish
and feed have been added. I can get a rough idea of N by ammonia, nitrite
and nitrate measurements, but would this be reliable? what about free
Nitrogen? How is Phosphorous and potassium affected by the addition of
fish, I know feed can cause eutrophication, but would you have any data on
the amount of P in a aquaculture system. Would you also have data on the
amount of Potassium (K), Calcium, etc in the system?

The reason for asking is that I am proposing a "biosystem" myself, and the
botanist that I am working with would like to know the amount of nutrients
in the water for the best plant selection. If statistical data cannot be
found, could you give a high/low range value?

What have you found to grow the best? I am thinking of growing sage,
sweetgrass, watercress, and maybe some sedges.

Thank you for your time,
