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

Table 3

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

Ammonia (mg/L)	Protein level (%)	HSI (%)	VSI (%)	CF (%)
0.02 mg/L	31.04	^ab	^cd	^ab
0.88 mg/L	22.64	^d	^d	^a
	27.26	^cd	^cd	^a
	31.04	^bcd	^abc	^ab
	35.63	^bc	^ab	^b
	38.47	^b	^a	^ab
	42.66	^b	^a	^ab

Values are (standard deviation) of three replicate per treatment, values in the same row within the same protein level sharing different letters are significantly different at , as determined by Tukey’s test. ; ; .
