Farmed Prawn Gut Health Microbiome

Prawn gut microbiome management is an emerging area that influences disease resistance and welfare in intensive production systems.

Key Facts

Prawn gut microbiome is shaped by diet, water quality, and production environment
Dysbiosis increases susceptibility to Vibrio and other pathogenic bacteria
Probiotics including Bacillus and Lactobacillus strains improve prawn gut health
Prebiotic supplements support beneficial bacterial populations in prawn guts
Research into prawn gut health is growing but lags behind fish and terrestrial livestock

Welfare Considerations

Gut health is a welfare determinant in prawn farming. Microbiome imbalance increases disease susceptibility and may directly cause gut discomfort if prawns have sufficient sentience. Probiotic supplementation improves gut health outcomes and reduces antibiotic dependence - a welfare, sustainability, and economic benefit simultaneously.

What You Can Do

Choose shrimp from farms using probiotic and prebiotic gut health management
Support research into prawn gut health and welfare implications
Advocate for gut health monitoring as a welfare indicator in certified shrimp production
