Fasting/re-feeding and water temperature promote the mobilization of body reserves in juvenile freshwater carnivorous catfish Lophiosilurus alexandri

We investigated the effects of water temperature and fasting on physiological and metabolic parameters of juvenile pacamã (Lophiosilurus alexandri). Fish subjected to fasting for 15 days followed by re-feeding for five days in two water temperatures (28 and 24 °C) were sampled after fasting and afte...

Zusammenfassung:We investigated the effects of water temperature and fasting on physiological and metabolic parameters of juvenile pacamã (Lophiosilurus alexandri). Fish subjected to fasting for 15 days followed by re-feeding for five days in two water temperatures (28 and 24 °C) were sampled after fasting and after re-feeding and compared to fish that did not experience fasting under the same temperatures. Glucose and triglyceride levels decreased during fasting for fish at both water temperatures (P
