Table 1 Chemical composition and isotopic composition of the lipid and lipid-free fraction of the feeds and grass carp analysed during the experiment

From: Leaves from banana (Musa nana) and maize (Zea mays) have no phyto-prophylactic effects on the susceptibility of grass carp (Ctenopharyngodon idella) to Aeromonas hydrophila infection

  1. Three different feeding regimes were applied as well as bacterial infection with Aeromonas hydrophila. In total, 18 groups were included and each combination of feeding group and infectious status (infected and mock infected) was represented by three tanks. The values in this table represent the mean and standard deviation for each parameter
