December 9th 2025

A groundbreaking study published in the Journal of Genetic Engineering and Biotechnology unveils a simplified, one-step disinfection technique for non-hardened rainbow trout eggs using Chloramine T (Halamid®). This innovative approach offers significant advantages over traditional methods, setting a new standard for aquaculture hygiene, operational efficiency, and environmental stewardship. 

Key Advantages of Chloramine T (Halamid®):

  1. Superior Disinfection Performance
  • Dosage: 100 mg/L Chloramine T in 0.75% NaCl solution for 40 minutes.
  • Achieves the highest reduction in bacterial load, outperforming both peroxide (Wofasteril®) and traditional iodophore (Buffodine®) treatments.
  • Maintains effectiveness throughout embryonic development, reducing pathogen risk and supporting fish health.
  1. Streamlined One-Step Protocol
  • Eggs can be fertilized and disinfected simultaneously in a single solution, eliminating the need for complex, time-sensitive two-step procedures.
  • Reduces handling errors and boosts efficiency, especially in large-scale fish farming operations.
  1. Safe for Fish Health
  • No negative impact on sperm motility, embryo viability, or larval development at recommended concentrations.
  • Maintains robust microbiome stability, supporting long-term fish health and resilience against pathogens.
  1. Environmentally Responsible
  • Used at much lower concentrations than traditional disinfectants.
  • Rapidly degrades in water, leaving no harmful residues—an ideal solution as regulatory scrutiny increases on older biocides.
  1. Practical and Cost-Effective
  • Simplifies workflow, saving time and resources for hatcheries and farms.
  • Offers a reliable alternative should iodophore products face future regulatory restrictions.

Industry Impact

The adoption of Chloramine T (Halamid®) as a one-step disinfectant marks a major leap forward for sustainable aquaculture. By combining operational simplicity, proven efficacy, and environmental compatibility, Halamid® empowers producers to safeguard fish health and productivity while meeting evolving regulatory and ecological standards.

About Halamid®:
Halamid® (Chloramine T) is a trusted disinfectant widely used in aquaculture and veterinary applications. Its proven safety profile and rapid biodegradability make it the preferred choice for modern fish farming.
