The effect of different dietary protein levels on the water quality and reproductive performance of Nile tilapia (Oreochromis niloticus) broodstock in biofloc system
Experimental analysis reveals optimal dietary protein at 32% improves water quality and reproductive performance in nile tilapia, suggesting benefits for aquaculture.
Key Points
A dietary protein level of 32% improved water quality and reproductive performance significantly.
The highest fertilization (93%) and hatching (89%) rates were observed in the 32% protein group.
Water quality metrics revealed the lowest TAN levels (0.21 mgL–1) in the 32% protein treatment.
No significant differences in mean final weight were found between fish fed with 32% and 38% protein.
