Innate immune response of pirarucu improved with yeast-supplemented diets

Aquaculture Reports, 2020
The present study evaluated the effects of dietary yeast supplementation on the growth and blood parameters of Arapaima gigas. Fish were fed with commercial feed supplemented with NuPro® at 0, 10, 40 and 80 g / kg for 30 days and, did not exhibit any difference in growth. Blood was analyzed at the end of the feeding trial and after handling stress.
