In intensive aquaculture systems, shrimp are frequently exposed to various stressors that weaken the immune system and increase the risk of disease. One of the most serious threats is Translucent Post-larval Disease (TPD), primarily caused by Vibrio bacteria.
To effectively prevent and manage TPD, protecting the mucosal barrier and stabilizing the gut microbiota from the early stages is a critical strategy.
Mucus – The Shrimp’s Natural Defense Line
Mucus plays a vital role as the shrimp’s first biological barrier, protecting the surface of the shell and intestines from pathogens present in the aquatic environment. This mucus is secreted by goblet cells in the epithelial tissue, covering the external surface and the entire digestive tract.
Key functions of mucus include:
- Acting as a physical barrier to block bacteria and viruses from directly contacting epithelial cells.
- Containing natural enzymes and antimicrobial molecules to neutralize pathogens on contact.
- Maintaining a stable microenvironment that supports the growth of beneficial microbiota, enhancing local immunity.
Why is the mucosal barrier vulnerable?
Under intensive farming conditions, various factors can disrupt mucus secretion and compromise the barrier’s function:
- Sudden changes in water quality
- Poor feed quality
- Excessive use of antibiotics
- Toxic contamination from heavy metals or ammonia
These disruptions can make shrimp more susceptible to disease, especially from Vibrio spp., a common bacterial group in aquaculture environments that can adhere to and damage intestinal epithelial cells — the primary cause of TPD.
Biological Solutions from Within – The Comprehensive Triple Product Strategy
To reinforce the mucosal barrier and minimize the harmful effects of Vibrio, farmers are encouraged to apply biological products that support digestion and immunity from the early stage.
The specialized product trio includes:
- AquaMos – Enhances natural immunity, reduces stress, and strengthens overall disease resistance.
- Pro Gut – Provides specialized probiotics and nutrients that nourish the intestinal mucosa.
- Clever – Contains potent antimicrobial yeast extracts that strongly inhibit Vibrio bacteria.
The specialized product trio includes:
- Lalpack Immune – Regulates the immune system and enhances disease resistance.
- Lalpack Probio – Balances gut microbiota and protects the shrimp’s intestinal lining.
- Clever – Contains potent antimicrobial yeast extracts that strongly inhibit Vibrio bacteria.
Key benefits:
