After refilling ponds, surviving microorganisms – including Vibrio parahaemolyticus, which causes EMS in shrimp – may benefit from the availability of nutrients in sediment and water and lack of competing microorganisms.
Monitoring of Vibrio bacteria in shrimp larvae determined a relationship among hepatopancreas color, bacteria concentration and signs of early mortality syndrome.
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
The pathogenicity of early mortality syndrome in shrimp is likely regulated by quorum sensing, which allows the Vibrio bacteria that colonize shrimp guts to coordinate the release of the toxin that damages shrimp digestive systems.
Early mortality syndrome (EMS) has led to reduced production in major Asian shrimp-farming areas and resulted in higher prices for shrimp. The situation provides opportunities for low-intensity producers in Latin America and other traditionally secondary shrimp producers to expand output
The emerging disease Early Mortality Syndrome has caused large losses among shrimp farmers. EMS is characterized by mass mortalities during the first 30 days of culture.
