Nutritional Value of Biofloc Meal for White Cachama (Piaractus orinoquensis): Effects of Inclusion Level on Digestibility, Growth Performance, and Protein Retention

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Biofloc technology (BFT) offers a sustainable aquaculture strategy; however, the value of its byproduct, biofloc meal (BFM), as a feed ingredient requires validation for key species. This study evaluated the use of BFM from a tilapia–molasses system as a feed ingredient for white cachama (Piaractus orinoquensis) juveniles.
