Stress in aquaculture can be modulated by specific stress-limiting factors such as Phytogenic Feed Additives (PFAs),
known for their welfare-promoting effects. Three stress trials with gilthead seabream were, therefore, conducted
aiming at evaluating the possible beneficial role of three PFAs as welfare-promoters under stress-induced farming
conditions, such as starvation (Trial I: Fish starvation for 14 days), high-density (Trial II: Fish were stocked in
aquaria at 1.2 Kg/m3 and 2 Kg/m3) and intense handling procedures (Trial III: Fish were kept out of water in the
open air for 5 min). Seven dietary treatments were supplemented with Cannabis sativa seed oil, Origanum vulgare,
and Cinnamomum zeylanicum essential oils at 1% and 2%. DNA damage in hepatocytes and erythrocytes and blood
cortisol were assessed as stress .. View more»
