Cecil, I will offer you what I am told by many customers....A 7.5:1 ratio of plants to fish has worked reliably. Start you seedlings/fingerlings at the same time. Stock your grow tank/beds with the intended harvest weights in mind and not the starting weights (for example, if harvesting fish at 1# and a stocking density of 1# per gallon water, stock 100 fingerlings {similar ratios for plants times 7.5 of fish harvest weight}) Your "node" will grow in sync and several "nodes" are required for constant harvesting. Fish reproduction should be avoided in your "grow-out" tanks.

As to the "amount" to feed the fish (and the species), this will always be determined by weight of fish at every stage of growth if you want to be that precise. In practice, you feed the fish all they can eat, without overfeeding, for rapid growth and plants will increase growth rates to compensate for the "extra" available nutrient...it seems to balance out well and can easily be tweaked for individual and changing goals.
