jpsdad, the above info that I have posted is some of the questions that arose from Professional hatchery techs and one of our managers while discussing the best way to conduct this in a manner it will be most useful to pond fish growers.
The fish will receive exactly the same amount of feed by weight each day, 6 days a week. To let the cat out of the bag to clarify what I wanted to add in the final report was that day 7 the weight doubles every week-only every 7th day-that's a planned part of the trial, and will be recorded as we go.
I will welcome criticism after my final report-I hope everyone tears it apart. Then we will learn from that.
If anyone has the time, the pond, money, fish and other equipment to try this, please feel free.
