feeding protocol by mass

[srmusc...@gmail.com]

I am examining the effects of both diet and exercise on swimming velocity, and I am in need of an amount of flake food to feed each fish daily (mg/fish). The literature that I have found mostly uses ad libitum for 5 minutes, or does not specify the amount that was fed. A few sources do specify the amount (in mg/fish), however the amount ranges from 1mg/fish twice daily to 10mg/fish twice daily. I would greatly appreciate any advice that anyone can provide or some consistent literature that I can work with. Literature that uses % by mass of fish would be helpful as well. Thanks.
