Addition Probiotics on Captive Fish Nutrition the benefits, water quality and productive performance: a review

Abstract

The processes of technological innovation influence the great advances in the world agribusiness sector. These progresses are the result of scientific and technological studies. In this context, fish farming appears as an alternative to diversify agricultural production, being the most responsible system in the world for food security. In addition, the practice of fish farming is a potential strategy for environmental conservation since it contributes to capture fisheries reduction. However, the traditional management commonly adopted in fish farming results in innumerable environmental consequences such as: pollution of water bodies and introduction of exotic species, generation of effluents, emergence of diseases in man and animals. Probiotics as a dietary supplement for captive-bred fish appear as an alternative resource, aiming to improve the zootenic and sanitary performance of fish, healthy conditions and increase production with efficiency. It should be noted that diets are related to ethological aspects, structural integrity, sanity, physiology, reproduction, growth, and sanitary or environmental conditions. The present study aimed to revise assessments on the use of functional food additives in captive-bred fish diet and the results obtained by their administration. A qualitative approach was used with a descriptive and documentary method. The data analysed here contribute to further studies and to glimpse the potentials of nutrition of captive fish, considerating that negative impacts to the environment, production and quality of fish can be mitigated.
