Abstract
Penaeus monodon is widely cultured in Asia; however, intensive farming practices often result in water-quality deterioration and compromised production performance. Copper-loaded montmorillonite (Cu-MMT) is a functional additive with adsorption and antimicrobial properties, yet the relative effectiveness of different application strategies remains insufficiently evaluated. In this study, 270 shrimp were assigned to three treatments: a control group (KZ), water application of Cu-MMT (PZ), and dietary inclusion of Cu-MMT (BZ). Juvenile Penaeus monodon with an initial body weight of 3.25 ± 0.15 g were used in the trial. Growth performance, intestinal histology, and rearing-water quality were assessed over a 56-day culture period. Shrimp in the BZ group exhibited a significantly higher weight gain rate (311.88 ± 38.17%) and survival rate (88.04%) than those in the KZ (247.45 ± 32.82%; 76.67%) and PZ (286.49 ± 29.78%; 83.33%) groups (p
