Fig. 9. Gross food conversion efficiency (CE) measured on a tank basis
(N=4 for control and low ammonia groups, N=3 for high
ammonia group) over 71 days in the three experimental treatments of Series 2:
nominal [TAmm]=0 µmol l1 (control),
70 µmol l1 (low ammonia) and 225 µmol
l1 (high ammonia). (A) Satiation-fed fish, (B) rationed
fish. Values are means ±1 S.E.M.
*Significant difference from control within the same panel. CE values for the
same treatments were all significantly lower in the rationed fish than in the
satiation-fed fish.
