Functional foods in rainbow trout (Oncorhynchus mykiss) production

Abstract

Nowadays, diet optimize and disease control are two principal goals to guarantee aquaculture expansion. Considering that the organisms are in captivity, it is difficult to provide all nutrients that organisms need in culture systems, that is why it is important to add different substances to improve their nutritional condition and obtain better growth and reproduction rates. For this reason, alternatives to improve nutrition and reduce diseases, using different strategies applied until now, have been researched. Such is the use of functional foods including nutraceuticals, prebiotics, probiotics and symbiotic, as a tool which allow counteract use of antibiotics, hormones and chemotherapeutics because of adverse effects that they generate. In Mexico, rainbow trout culture, for their economic value, occupies seventh place with an annual growth of 3.98% in last 10 years, which denotes the importance of the species. The goal of this study was to make a functional food review and their obtained benefits until now in Oncorhynchus mykiss
