Here's a few of the questions that have come to mind over time about several aspects of supplemental feeding and a good part of why I'm doing this.
One thought I wonder about is if we provide feed at a certain amount, there are many variables that need to be considered.
1. Do we feed until fish stop consuming? If so, what if they WANT to consume more of one feed than another.
2. If we go by % of body weight, again, how do we know they won't eat more (or less) of one brand than the other?
What I intend to record is how much do the fish want of each brand, then at the end I will determine what that percentage is and see what total growth actually was for that amount of food. I am expecting similar results from both but there are other parts to the feed besides protein and fat-how does that volume affect growth? I don't think we have anything but assumptions on that.
What if we get done and find that 30lbs of one feed converts to the same gain as 35lbs of the other??
I have a lot of questions and that's why I'm doing this.
