Just a thought FWIW. Couldn't the question be answered (at least if its possible) by calculating a ponds limits for carrying capacity based on past research?

What would be the maximum carrying capacity (lbs of fish) of an unfed or fed pond with x and y dimensions be? Along with the water limitations, factoring in the constraints of inputs from the owner (time and money) along with fish species and geographical location. Once that number is calculated, simply divide it over 52 weeks.

If the carrying capacity of a fed, mid effort managed pond, in the south, with aeration, stocked with CC and BG is between 750-850lbs/acre, your weekly harvest would be:

Pond size 1/8 acre; 750/8= 93.75lbs carrying capacity

Assume 50% of the population is of harvestable size; 93.75/2=46.8lbs

Weekly harvest of; 46.8/52= .9lbs of fish
