🌱 Soya Hulls – Properties and Use
Soya hulls are the outer coverings of soybeans, produced during soybean processing. They are commonly used in aquaculture and shrimp keeping as a high-fiber, plant-based supplement that supports digestion and overall health.
🔎 Composition & Nutritional Value
Fiber: 35–45% – improves gut motility and digestion
Protein: 10–15% – moderate protein source
Fat: 1–2% – low-fat content
Minerals: calcium, potassium, magnesium, phosphorus
Carbohydrates: ~30–35% – energy source
Phytoestrogens: plant compounds with mild bioactive effects
🌟 Properties & Benefits
1. Nutritional Benefits
High fiber content supports healthy digestion in shrimp and fish
Provides moderate protein, contributing to growth and molting
Contains minerals essential for exoskeleton development
Slow-to-digest carbohydrates provide steady energy
2. Aquarium Use
Offered dried and crushed as a supplemental food
Can be soaked or mixed with other feeds (e.g., spirulina, alfalfa, nettle)
Promotes biofilm growth, which is naturally consumed by shrimp
Safe for shrimp, fish, and snails when used in moderation
3. Effects on Shrimp
Supports growth and healthy molting
Improves gut health and nutrient absorption
Enhances feeding behavior, stimulating grazing
⚡ Tips
Feed sparingly, as excessive amounts may cloud water or decompose
Can be combined with high-protein foods for balanced nutrition
Best for low-tech shrimp setups where natural biofilm growth is desired
