Authors discuss the mechanisms of competitive exclusion of pathogens to improve selection and application of probiotics in shrimp aquaculture.
Study assessed shrimp juveniles fed enriched probiotic formulations, improving our understanding of the composition and dynamics of intestinal microbiota.
A review of the application of probiotics in shellfish aquaculture, methods of administration, mode of actions and their enhancing effects.
Guatemala’s shrimp-farming growth is due to a highly intensive system of small ponds and shorter cycles. Production of close to 25,000 metric tons is expected in 2018.
Pond microbial communities are a critical and often overlooked component of aquaculture ecosystems. Bacterial amendments like probiotics provide significant support to shrimp farmers around the world.
This study evaluated a commercially available prebiotics and probiotics under conditions simulating commercial production in hybrid catfish. Results showed that the various dietary treatments did not have any significant effects on processing characteristics or composition.
Effective implementation of biosecurity protocols in shrimp farming requires awareness, discipline and a commitment by farm owners to implement them. The authors take a close look at intensive nurseries and how to exclude pathogens, predators and competitors.
Results of a feeding study supplementing probiotics in the diet showed that when the Bacillus species were complemented in an appropriate concentration into feeds, the growth and feed efficiency of whiteleg shrimp could be improved.
The application of probiotics, prebiotics and lipopolysaccharides has shown positive results with farmed shrimp, and is a very promising field, but more research is needed to clarify and foresee the molecular impact of these biological entities.
