| Özet |
| This study evaluated the effects of dietary supplementation with Ulva lactuca (5% = ULM5; 10% = ULM10) on Nile tilapia (Oreochromis niloticus) under prolonged intermittent fasting (1 week fasting/1 week feeding for 12 weeks). While fasting reduced growth and body composition parameters, protein content remained above 20% across all groups. ULM5 improved growth performance under normal feeding, whereas ULM10 enhanced antioxidant defense [↑SOD (superoxide dismutase), ↑CAT (catalase), ↓LPO (lipid peroxidation)], particularly during stress. Digestive enzyme activities declined during fasting but recovered in U. lactuca-fed groups. These findings suggest that U. lactuca, especially at 10%, may support physiological resilience and oxidative balance during nutritional stress, highlighting its potential as a functional feed additive in sustainable aquaculture. |
