L‑Arginine is a must‑have amino acid in fish feed to boost growth, digestion, immunity and antioxidant defense.

Core Benefits
Optimize Growth & Metabolism
It triggers fish’s growth‑control mechanism to build more muscle protein and keep blood sugar and fat levels balanced. Arginine and lysine compete for the same absorption channels in fish intestines, and this competition varies among different fish species.
Improve Gut Function
Proper arginine raises digestive enzyme activity, lengthens intestinal villi for better nutrient uptake, and protects gut barrier integrity.
Boost Non‑Specific Immunity
Fish mainly rely on their natural self‑defense system. Arginine helps produce nitric oxide to boost immune cells and antibacterial substances, ease inflammation, speed up wound healing, and help fish withstand ammonia and pathogen infections.
Fight Oxidative Stress
It activates fish’s natural antioxidant system to boost protective enzymes, lower harmful oxidative toxins, remove cell‑damaging free radicals and protect the liver and intestines.
Most fish cannot synthesize sufficient L‑arginine endogenously to meet growth requirements, so feed supplementation is necessary. Optimal dosage differs widely by fish species (3.35%–8.1% of dietary crude protein), affected by fish size, growth phase and performance metrics. Appropriate arginine supplementation delivers all‑round advantages for sustainable fish farming.
