This study evaluated through in vitro analyses the antimicrobial effectiveness of natural products used for P. vannamei bacterial diseases and antibiotics against pathogenic Vibrio strains circulating in Ecuadorian hatcheries.
Desafíos de laboratorio y un estudio caso-control se utilizaron para determinar los efectos de la infección por EHP en dos enfermedades de Vibrio: necrosis hepatopancreática aguda (AHPND) y necrosis hepatopancreática séptica (SHPN).
Laboratory challenges and a case-control study were used to determine the effects of EHP infection on two Vibrio diseases: acute hepatopancreatic necrosis disease (AHPND) and septic hepatopancreatic necrosis (SHPN).
Un estudio realizado en Huila, Colombia, probó los efectos del aditivo de alimentos diformato de potasio sobre el desempeño de la tilapia juvenil. Los resultados mostraron un índice de productividad de peces mejorado, menor mortalidad y mejoras en el aumento
A study conducted in Huila, Colombia, tested the effects of the feed additive potassium diformate on the performance of juvenile tilapia. Results showed an enhanced fish productivity index, lower mortality and improvements in weight gain.
Early Mortality Syndrome has devastated farmed shrimp in Asia and Latin America. With better understanding of the pathogen and the development and improvement of novel strategies, shrimp farmers are now able to better manage the disease.
A novel blend of organic acids (OAB) microencapsulated in a lipid matrix and supplemented in the diets of Litopenaeus vannamei enhanced their growth, phosphorus utilization, resistance to Vibrio harveyi and immunity. This may have implications as an eco-friendly prophylactic strategy.
A study confirmed the utility for improved polymerase chain reaction (PCR) detection of the Vibrio bacteria that cause acute hepatopancreatic necrosis disease (AHPND) in asymptomatic shrimp by permitting the shrimp to expire and decompose for several hours prior to preservation
Strategies to control Vibrio bacteria at aquaculture farms must revolve around limiting inputs, including those from postlarvae suppliers, those that come in with the water, those that remain in the soil between crops and those in the feed and accumulated
