| An estimate of the nitrogen that will
be excreted into the water can be empirically calculated by the following; |
| Nw = NT - (NT X
1/FCR) |
| where, |
NT = Total nitrogen added to the
system |
| |
Nw
= Nitrogen excreted into the water |
| This is not exact as it does not allow
for lipids and other nutrients in the diet which may be retained in the
fish, but is a good estimate and errs on the side of safety. |
