## 4 Discussion
Interestingly, the intestinal health research of fish fed soybean-based feeds has gone beyond the traditional highly carnivorous species reaching a wide range of species from different feed, salinity and water temperature preferences, including for example common carp [14; 15], grass carp [26], kingfish [7; 12], totoaba [5; 6], and largemouth bass [8]. \begin{table}
