Dietary protein-to-carbohydrate ratios affect metabolism and growth of juvenile surubim cachara (Pseudoplatystoma reticulatum)

This study was conducted to evaluate the effects of dietary carbohydrates (CHO) and protein on growth performance, nutrient retention, blood metabolites, tissue energy reserves (hepatic glycogen and lipids, mesenteric fat index, and hepatosomatic index), and key metabolic enzyme activities (hexokinase, glucokinase, glucose-6-phosphate dehydrogenase, and aspartate aminotransferase) of surubim cachara (Pseudoplatystoma reticulatum).
