Enhancing Feed Digestibility, Growth, and Water Quality
Crab Enzyme Complex is a specialized biological enzyme formulation developed for modern aquaculture systems,
particularly crab farming. This advanced multi-enzyme blend enhances feed digestion, promotes nutrient absorption, supports
healthy molting, and improves pond water quality. Designed with a deep understanding of crab digestive physiology,
it offers a sustainable solution for farmers seeking higher yields and healthier crabs.
The product integrates biotechnology and environmental science, combining multiple hydrolytic enzymes that work
synergistically to break down proteins, carbohydrates, and fibers present in aquafeeds. This ensures more efficient feed
conversion, minimizes waste, and stabilizes water conditions — key factors in profitable aquaculture production.
Key Technical Features
- Comprehensive Multi-Enzyme System: Contains protease, cellulase, amylase, β-glucanase, xylanase,
and related catalytic proteins that target diverse feed substrates to improve digestion efficiency. - Improved Feed Conversion Ratio (FCR): Enhances nutrient uptake and energy utilization,
leading to faster growth rates and reduced feed costs. - Optimized Digestive Performance: Designed for the specific pH range of crab digestive tracts,
ensuring high enzymatic activity in both freshwater and brackish environments. - Supports Water Quality Management: Reduces residual organic matter, ammonia, and nitrite buildup
by breaking down uneaten feed and waste materials. - Safe & Eco-Friendly: 100% free from antibiotics or synthetic chemicals. Fully compatible
with probiotics, microbial preparations, and ecological farming practices.
Product Specifications
| 外貌 | Light yellow fine powder |
| 包装 | 1 kg / bag (sealed aluminum composite pouch) |
| 贮存 | Store in a cool, dry, and well-ventilated place; avoid moisture and direct sunlight. |

Application & Dosage
- Feed Supplementation: 混合 3 – 5 g of Crab Enzyme Complex per kilogram of feed.
Dosage may be adjusted according to feed composition and culture conditions. - 水处理： Dissolve and apply 1 – 3 g per cubic meter of aquaculture water
(equivalent to 1 – 3 ppm). Disperse evenly for best results. - Compatibility: Suitable for co-application with probiotics, microbial regulators, or other
eco-friendly aquaculture agents.
The enzyme activity remains stable across a wide range of water salinity levels and temperatures,
making it ideal for year-round use in both freshwater and marine crab farming systems.
Functional Benefits
- Boosts feed utilization and reduces waste accumulation.
- Improves digestion and nutrient assimilation during all crab growth stages.
- Enhances shell hardening and molting uniformity.
- Improves water clarity and reduces harmful ammonia concentrations.
- Promotes immunity and disease resistance through better gut health.
- Supports sustainable aquaculture with lower environmental impact.
Mechanism of Action
Each enzyme component in the Crab Enzyme Complex plays a targeted role:
- 蛋白酶 hydrolyzes protein chains into absorbable amino acids for rapid tissue development.
- 淀粉酶 breaks down starch into glucose, providing an immediate energy source for growth.
- Cellulase and Xylanase degrade complex plant cell walls, enhancing digestion of plant-based feed ingredients.
- β-葡聚糖酶 improves intestinal health and stimulates immune response.
These enzymes operate synergistically to improve nutrient bioavailability and reduce undigested residues,
leading to cleaner pond environments and improved overall productivity.
Recommended Usage Fields
- Crab aquaculture (freshwater, seawater, or mixed systems)
- Feed manufacturing and enrichment for aquatic animals
- Environmentally friendly aquaculture and recirculating pond management
Sustainable Aquaculture Impact
By integrating Crab Enzyme Complex into feeding regimes, farmers can achieve higher productivity with reduced
ecological footprint. The enzymatic degradation of organic matter not only improves water conditions but also
minimizes the use of antibiotics and chemicals, contributing to responsible aquaculture practices.
Continuous use leads to enhanced feed efficiency, faster growth, better survival rates, and a more balanced
pond ecosystem. Crab Enzyme Complex represents a proven biotechnology-driven solution for next-generation
aquaculture operations worldwide.
