Research has shown that probiotics and prebiotics can help mediate stress responses and improve disease resistance, growth performance, feed utilization, carcass composition and other traits by stimulating animals’ innate immune systems.
To develop probiotics for marine shrimp, authors chose a bacterium with high growth velocity and great capacity to inhibit pathogens, among other traits.
Probiotics administered in feeds provide competitive exclusion of pathogenic bacteria, create conditions unfavorable for pathogens and modulate intestinal immune responses.
Research with sturgeon and carp species indicated that encapsulated artemia has high potential to carry probiotics or other beneficial microorganisms.
As the demand for aquaculture products increases, so does the search for environmentally friendly alternatives to antibiotics. Alternatives to antibiotics include dietary prebiotics, probiotics and synbiotics.
There is increasing evidence that natural feed additives can have beneficial effects on aquaculture animals by supporting well-balanced gut microflora and improving gut health.
The use of probiotics in aquaculture is steadily gaining momentum, supplementing or replacing the use of antimicrobial compounds in disease control.
Studies at a commercial sturgeon farm that experienced serious disease effects from varied bacterial pathogens in fish yielded positive results for probiotic treatments.
In a study, three probiotics applied to shrimp pond water throughout a culture period were not effective in preventing Vibrio harveyi outbreaks.
