Disease problems on shrimp farms may be partly driven by an interaction between management practices that cause inbreeding in small hatcheries and the amplification by inbreeding of susceptibility to disease and environmental stresses. 

1-monoglycerides are known for their antibacterial and antiviral effects in the human pharmaceutical and animal husbandry industries. As a substitution for the preventive use of antibiotics, these molecules are being evaluated in the fight against AHPND. 

Ideally, farmers need to create conditions that make it harder for the pathogenic Vibrio that causes AHPN to colonize animals’ stomachs and for the toxin to produce its pathology. Exclusion where possible and appropriate management of ecosystems offer hope in addressing AHPN. 

A laboratory study at the University of Arizona examined the effects of tilapia to control EMS and mortality in Pacific white shrimp.in controlling AHPN. 

Vibrio parahaemolyticus, a strain of which is the cause of acute hepatopancreatic necrosis (AHPN), has both virulent and benign strains. This strain colonizes the stomachs of shrimp by the formation of a biofilm, which protects it from antibiotics and other potential treatments.
