The Requirement and Protective Effects of Dietary Protein against Chronic Ammonia Exposure in Juvenile Genetically Improved Farmed Tilapia (Oreochromis niloticus)

Table 2

Growth performance of GIFT juveniles fed diets with different protein levels under low or high ammonia exposure for 8 weeks.

Ammonia (mg/L)	Protein level (%)	IBW	FBW	WGR	SGR	FE	PER	SR
0.02 mg/L	31.04		^d	^d	^d	^a	^c	^b
0.88 mg/L	22.64		^a	^a	^a	^b	^g	^a
