Influence exerted by certain factors during rearing and before slaughter on post-mortem characteristics of sea bass

摘要

The various practices adopted during rearing may cause disturbance to fish, leading to notable physiological reactions and considerably affecting their infra vitam performance, as well as the quality of the food product obtained. The aim of this work was to assess for European sea bass (Dicentrarchus labrax) the influence of the level of oxygen (DO) in the rearing water, of the density offish in the hour prior to death, and the effect of capture repeated in the same tank 24 hours after the first capture on the values of some parameters measured at a muscular level during the first 24 hours after slaughter.
