| dc.description.abstract | Skin mucus contributes to the fish defense against the surrounding environment and reflects the state of health of the fish; therefore, it is a low-invasive and non-lethal matrix appropriate to assess welfare. However, more information is required on the response to stressors in Latin America fish species. At this regard, in Colombia the most important native fish species used in aquaculture is cachama blanca (Piaractus orinoquensis) begin necessary to depth in their physiological knowledge. Therefore, this study compared the skin mucus as another study matrix in fish exposed to low concentrations of dissolved oxygen in the water as stress factor. This study was carried out in P. orinoquensis specimens subjected to several intervals of hypoxic conditions and subsequently sampled after 0, 2, 4, 6, 24, 48 and 72 h of repetitive poststress condition. Skin mucus and plasma were collected and a battery of biochemical biomarkers were measured in both matrices. The analysis showed significant shifts of indicators such as glucose activity, protein concentration and lactate activity being significantly higher in skin mucus than in plasma compared to control and also having a highest response at 6, 24, 48 and 72 h post-stress; however, only significant variations were found in plasma cortisol levels at 4, 6 and 24 hours compared to the control. These results demonstrate that skin mucus in P. orinoquensis can be used as non-invasive matrix for stress assessment in fish, since several biomarkers presented a similar pattern of response in the skin mucus, becoming an appropriate matrix to evaluate either health of fish and aquatic systems.
