Dietary protein requirement for tambaqui cultivated in biofloc and clear water systems

Dietary protein requirement for tambaqui cultivated in biofloc and clear water systems

This study aimed to compare tambaqui ( Colossoma macropomum ) juvenile (9.20 ± 0.23 27 g) growth performance, digestive enzymes, and body composition when offered different feed crude protein (CP) levels (24, 28, and 32% CP) in biofloc (BFT) vs. clear water (CW) systems over 60 days in a 2 × 3 facto...

Zusammenfassung:This study aimed to compare tambaqui ( Colossoma macropomum ) juvenile (9.20 ± 0.23 27 g) growth performance, digestive enzymes, and body composition when offered different feed crude protein (CP) levels (24, 28, and 32% CP) in biofloc (BFT) vs. clear water (CW) systems over 60 days in a 2 × 3 factorial experimental design. Water quality was also measured throughout the experiment. Decreased nitrite ( P
