In the dynamic world of shrimp aquaculture, early-stage nutrition is critical to hatchery success. Hatcheries worldwide face challenges such as variable live feed quality, biosecurity risks, and inconsistent survival rates. To address these challenges, Zeigler has developed EZ Larva Ultra and EZ Artemia Ultra—two next-generation liquid diets designed to revolutionize shrimp larval nutrition. These advanced liquid feeds provide hatcheries with a reliable, biosecure, and highly digestible alternative to conventional live feeds.
The Advantages of Liquid Nutrition
Improved Buoyancy & Stability
One of the key benefits of Zeigler’s liquid diets is their ability to remain evenly suspended in water, ensuring optimal access to nutrients for shrimp larvae. Unlike dry feeds that can settle too quickly, the liquid formulation enhances nutrient availability and consumption.
Enhanced Gut Health & Survival
EZ Larva Ultra and EZ Artemia Ultra are packed with probiotics and Zeigler’s proprietary Vpak, a powerful blend of immunostimulants. The probiotics, Rescue and Remediate, are specifically designed to reduce Vibrio spp. in the animal gut and to minimize ammonia and excess organic material in culture systems. This powerful combination promotes gut health, strengthens immune responses, and helps maintain water quality—critical factors in improving survival and resilience in shrimp larvae.
Consistent, Biosecure Nutrition
Live feeds such as Artemia nauplii and algae introduce variability into hatchery operations, making it difficult to achieve consistent results. Zeigler’s liquid diets eliminate this uncertainty by providing a controlled, biosecure nutritional solution. Each batch is formulated to deliver uniform nutrient content, reducing dependency on live Artemia and algae while ensuring predictable performance.
Cold Processed for Maximum Efficacy
Zeigler’s liquid feeds utilize a cold processing technique that preserves the integrity of probiotics and other sensitive ingredients within the microcapsules. This ensures the effective delivery of nutrients and beneficial bacteria directly to the shrimp’s digestive system, enhancing digestion and overall health.
A New Era in Artemia Replacement
EZ Artemia Ultra is specifically designed as a high-performance alternative to live Artemia nauplii. With enhanced microencapsulation technology, this liquid diet delivers:
- Higher particle nutrient density for superior digestibility
- Upgraded microcapsules for optimal nutrient release
- Proven 100% Artemia replacement in commercial hatchery trials
By replacing live Artemia, hatcheries gain greater control over their feeding process, improving efficiency, reducing costs, and enhancing biosecurity.
The Ultimate Algae Alternative & Functional Feed
EZ Larva Ultra serves as a highly effective alternative to algae, replacing up to 100% of traditional algae feeds from the Z2 larval stage onward. Key benefits include:
- Targeted probiotics to support gut health and water quality
- Organic acids and antioxidants for enhanced resilience and immune function
- Consistent, controlled nutrition to optimize hatchery outcomes
Proven Results in Hatchery Trials
Hatcheries adopting Zeigler’s liquid diets have reported remarkable improvements in performance. In AHPND challenge trials, the combined use of EZ Larva Ultra and EZ Artemia Ultra increased survival rates by 33%. Additionally, their high lipid content supports energy reserves during transport, ensuring stronger, more resilient larvae upon stocking.
Why Hatcheries are Making the Switch
As the industry continues to move toward more controlled and biosecure feeding solutions, Zeigler’s EZ Larva Ultra and EZ Artemia Ultra stand at the forefront of innovation. By replacing or supplementing live feeds with these advanced liquid diets, hatcheries can:
- Enhance survival and larval development
- Reduce dependency on Artemia and algae
- Improve water quality and biosecurity
- Achieve greater efficiency and consistency
For hatchery managers looking to optimize their operations and ensure the highest quality shrimp production, Zeigler’s liquid nutrition solutions provide the ultimate competitive advantage.
