Fig. 7. Specific growth rates (SGR) of individually marked fish over 71 days in the
three experimental treatment groups of Series 2: nominal
[TAmm]=0 µmol l1 (control,
N=64), 70 µmol l1 (low ammonia, N=64),
and 225 µmol l1 (high ammonia, N=48). (A)
Satiation-fed fish, (B) rationed fish. Values are means ±1
S.E.M. *Significant difference from control
within the same panel. SGR values for the same treatments were all
significantly lower in the rationed fish than in the satiation-fed fish.
