When I went to Sakai Fish Farm this year, they had the combined weight of the koi written on paperwork on their automated feeders--clearly using a system.

I have no exact way. As a matter of fact I use the comparison method. I can still see that 4 lb. bass I cought like it was yesterday.
So say 18 to 19 inches 3 lbs
20 to 22 inches 4.5 lbs.
In order to be measure food weight intake apples to apples using natural food intake such as plants or plankton, the dry pellets should be hydrated with water for a more acurate comparison. I am going to measure one cup dry and one hydrated to see the absorption weight amount.
