Use of prebiotics, probiotics and synbiotics as a nutritional tool in aquaculture.
Aquaculture is expanding significantly in Brazil and worldwide. According to a report from the Food and Agriculture Organization of the United Nations (FAO), the country will have a 104% increase in fish production by 2025.
Improving performance in species of zootechnical interest reared under intensive systems is a major interest in fish farming. Considering the fact that productive success depends upon: genetics, management, appropriate nutrition according to the species being produced and its cultivation system. Given the current demands from a growing aquaculture industry, it is necessary to conduct research that leads to the creation of complete, efficient and economically viable diets.
Additives that contribute to enhancing fish metabolism and health, promoting a satisfactory development of the animal, represent a valuable tool. As these can positively influence growth, reproduction and overall performance parameters.
Aquaculture requires adequate water resources, where fish or other species of productive interest will remain throughout their cultivation period. Thus, disease proliferation or any other distortion that may affect productive equilibrium can lead to negative impacts within the rearing environment. Resulting in important economic losses for the sector.
Antibiotic use in aquaculture has been a tool of choice for disease control and improving zootechnical performance in the past decades. However, antimicrobial abuse has led to the rise of multiresistant pathogens, leading to significant health risks both for animals and humans worldwide. [register]
In addition, residues from these compounds remain in fish tissues for considerable periods of time. Allowing them to reach consumers, as well as promoting imbalances in the beneficial biota of aquatic environments.
Faced with these undesirable implications, there is a growing need to find alternative dietary supplements for fish. Amongst which the use of probiotics, prebiotics and synbiotics represent a promising alternative. These types of products possess the ability to stimulate animal’s immune function by nourishing and promoting the growth of beneficial microorganisms. Which in turn are capable of enhancing the host’s metabolism through production of certain metabolites as well as inhibiting the proliferation of pathogenic microorganisms.
