Yes Frank, I guess whatever spurs consumption is in overdrive for YOY but as fish get older their rates of consumption decrease. Now they eat as much as they ever did because they are bigger but the specific rates do fall until adulthood is reached. For every variable that is preceded by the word specific this means in relation to the weight of a fish at the start of a daily increment. FCR, SGR, SFR, SMR are all dimensionless entities (or ratios of the same units). Whether you work in metric or English units, the values of these variables are always the same. They are universal. To someone like me, reducing natural relationships to such intrinsic universal meaning is something of beauty. I appreciate that you liked it.

Frank, also I noticed you downloaded it. Do it again, I need to modify a formula on the second tab so changes of SFR would compute in the SGR calculation.
