Effects of Feeding Frequency for Nile Tilapia Fingerlings (Oreochromis niloticus)

Table 3

Total nitrogen (TN) and total phosphorus (TP) in water during the experimental period with Nile tilapia (Oreochromis niloticus).

Variable (mg L^-1)	Feeding frequency
	F4	F5	F6	F7	F8	F9
T nitrogen	^b	^a	^a	^ab	^ab	^ab
T phosphorus	^b	^ab	^a	^ab	^ab	^a

Values without letters or with the same letters, which are on the same line, indicate that there was no significant difference (), whereas those with different letters indicate a significant difference (). F4: Fed 4 times a day; F5: fed 5 times a day; F6: fed 6 times a day; F7: fed 7 times a day; F8: fed 8 times a day; F9: fed 9 times a day.
