title: Aloysia triphylla essential oil as additive in silver catfish diet: Blood response and resistance against Aeromonas hydrophila infection.
abstract: The essential oil of Aloysia triphylla (EOAT) is a promising product with potential use in aquaculture systems. This study evaluated hematological/biochemical responses and survival of silver catfish (Rhamdia quelen) fed a diet containing EOAT and infected by Aeromonas hydrophila. After 21 days of feeding trial, fish were infected with A. hydrophila following a 10-day period of observation. Blood collection was performed before and after the bacterial challenge. Dietary EOAT by itself seems to affect some blood parameters, decreasing total leukocyte, lymphocyte, and neutrophil counts and increasing total protein values. However, 2.0 mL EOAT/kg diet showed a possible potential protective effect after A. hydrophila infection, maintaining the evaluated parameters similar to basal values (from healthy fish before the feeding trial) and promoting survival of silver catfish.
