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.

Dietary Tea Polyphenols Improve Growth Performance, Physiological Health and Economic Efficiency in Nile Tilapia (Oreochromis niloticus)

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Tea polyphenols (TPs) are natural bioactive compounds extensively used in aquaculture diets as a functional supplement because of their antioxidant, antimicrobial and immunomodulatory potential. Four isonitrogenous diets (crude protein: 30%) were designed with incorporating TPs at levels of 0% (control, TPs‐0), 0.025% (TPs‐1), 0.05% (TPs‐2 ...
