This study aimed to evaluate the effects of Hermetia illucens (black soldier fly) exuviae, as a chitin source (CHI), and lauric acid (LA) on the intestinal physiology of rainbow trout ( Oncorhynchus mykiss ). Four isoproteic and isolipidic semi-purified diets were tested: a control diet (CTRL), a diet with 1.5% CHI (C-CHI) and two diets with 1.5% CHI and LA at 0.1% and 0.2% (C-CHI-LAU1 and C-CHI-LAU2, respectively). A total of...

The aim of the present work was to investigate the influence of fasting and refeeding on body condition, gut physiology and microbiota in reared O. mykiss . Ninety-six fish were randomly allotted among three groups subjected to different feeding plan: C (control, fed for 5 weeks); R (restricted ration over 3 weeks followed by 2 weeks feeding); F (fasted over 3 weeks followed by 2 weeks feeding) in a well’s fresh water flow-thr...

Microalgae have been used as live food in aquatic species. In recent years, the interest in microalgae has considerably increased, thanks to the evolution of production techniques that have identified them as an ecologically attractive aquafeed ingredient. The present study provides the first data about the effects of dietary inclusion of a microalgae consortium grown in a high-rate algal pond system on zootechnical performanc...
