Effects of Probiotic Bacillus sp. on Food Convertion and Growth of Catfish Pangasius hypophthalmus

<p>A triplicate experiment was conducted to evaluate the addition of probiotic <em>Bacillus </em>sp. into the diet on feed convertion and growth of catfish <em>Pangasius hypophthalmus. </em>Twenty fish with an initial body weight of 1,85 <em>± </em>0,09 g we...
