“…Physiologically and nutritionally important long‐chain n‐3 and n‐6 polyunsaturated fatty acids such as eicosapentaenoic acid (EPA; 20:5n‐3), docosahexaenoic acid (DHA; 22:6n‐3) and arachidonic acid (ARA; 20:4n‐6) were higher in muscle and liver in comparison to the adipose tissue. This indicates tissue specificity and warrants further investigation to enhance the fatty acid profile in the edible muscle part, i.e., increasing PUFAs and lowering saturated fatty acid levels (Arslan et al, 2016).…”

The drop in temperature during the winter months can lead to a decrease in growth, induce metabolic stress, and increase mortality incidences. The present study evaluated the potential of functional feed additives in mitigating the negative impacts of winter‐rearing conditions in striped catfish (Pangasianodon hypophthalmus). Four test diets were evaluated over a twelve‐week feed trial: (1) zinc‐acetate (Zn‐acetate), (2) selenomethionine (Se‐Met), (3) β‐glucan, and (4) control with no added feed additive. The survival rate in the β‐glucan (95.00%) and Zn‐acetate (93.30%) dietary groups was higher than the control (78.30%) and Se‐Met (85.00%). Fish fed with the β‐glucan had the highest weight gain (20.75% increase), specific growth rate (13.75% increase), and lower feed conversion ratio (9.64 % decrease). However, feed additives did not influence the fatty acid profiles or whole‐body proximate composition. Although, Zn‐acetate and Se‐Met had higher body ash content. Serum cortisol and glucose levels were lower in β‐glucan and Zn‐acetate than in other treatment groups. All feed additives resulted in higher superoxide dismutase, glutathione peroxidase, and catalase activity in the liver and muscle. This study found that β‐glucan and zinc‐acetate can improve cold stress resistance and offer a sustainable strategy for catfish rearing over winter.
