A recent audit of Bangladesh’s pangasius farms found that only 35 percent of farmers were able to meet sustainability and quality indicators at the “best” or “good” level – how can this be improved?

A recent feed trial has found that supplementing Nile tilapia diets with bakers’ yeast (Saccharomyces cerevisiae) can change the fishes’ intestinal morphology, leading to improved nutrient uptake, immune responses and growth performance.
