A combined in vivo and in vitro approach to evaluate the influence of linseed oil or sesame oil and their combination on innate immune competence and eicosanoid metabolism processes in common carp (Cyprinus carpio)

Total replacement of fish meal by enriched‐fatty acidHermetia illucensmeal did not substantially affect growth parameters or innate immune status and improved whole body biochemical quality of Nile tilapia juveniles

“…There was no growth improvement in tilapia when either dietary α‐linolenic or n‐3 PUFA were provided (Takeuchi et al, 1983) and the use of conjugated α‐linolenic between 0.5–1.0% and 0.5–2.5%, at the expense of soybean oil and fish oil, respectively, had no significant effect on the growth performance or feed utilization of Nile tilapia or their GIFT strain (Luo et al, 2012; Santos et al, 2011). Similar results were observed in juvenile common carp whose growth performance increased with the total replacement of fish oil by sesame oil deficient in ALA and DHA (Nguyen et al, 2020). The lack of positive effects of dietary supplementation in PUFAs or LC‐PUFAs on growth could be due to the differences in the doses used or to the interference with the high endogenous hability of the latter species for LC‐PUFAS biosynthesis.…”

Quillaja saponaria and/or linseed oil improved growth performance, water quality, welfare profile and immune‐oxidative status of Nile tilapia, Oreochromis niloticus fingerlings

“…Numerous studies had stated that increasing dietary fat content within the proper range could improve growth, feed efficiency and protein deposition and reduce production costs in some fish species, such as tilapia (Chou & Shiau, 1996; Li et al, 2016). Linseed oil (LO) that contains a high level of polyunsaturated fatty acids (PUFAs) is regularly used in aquafeeds and medical products (Ferreira et al, 2015; Li et al, 2016; Ma et al, 2018; Nguyen et al, 2020). The PUFAs can be converted into a long‐chain PUFAs (LC‐PUFAs) such as linoleic acid (LA) to arachidonic acid (ARA); α‐linolenic acid (ALA) to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) throughout the processes of biosynthesis (Tocher, 2003), but this process is specific (Monroig et al, 2013).…”

Digestibility of Different Plant-derived Oils and their Influence on Fatty Acid Composition in the Liver and Muscle of Juvenile Common Carp (Cyprinus Carpio)

“…In several cases, especially in salmonid species, the reported results were similar, i.e. limited or no significant reductions of growth rate or feed utilization when 100% of the fish oil was replaced by plant oil (Peng et al, 2016;Mellery et al, 2017;Nguyen et al, 2019a). On the other hand, for some other fish species, the use of dietary plant oil instead of fish oil has induced a poor growth performance (Geay et al, 2011(Geay et al, , 2015Ren et al, 2012;Ti et al, 2019).…”

“…Globally, the reduction in availability of feed ingredients, especially fish meal and oil, is considered among the main constraints of aquaculture development (Tocher, 2015;Nguyen et al, 2019aNguyen et al, , 2019b. Therefore, the strategy of exploring other alternatives such as plant-based products and their valorizations is encouraged.…”

“…On the other hand, for some other fish species, the use of dietary plant oil instead of fish oil has induced a poor growth performance (Geay et al, 2011(Geay et al, , 2015Ren et al, 2012;Ti et al, 2019). Fish LC-PUFA composition is strongly affected by the dietary FA profile (Nayak et al, 2017;Torrecillas et al, 2017;Nguyen et al, 2019a;Ti et al, 2019). Common carp is able to synthesize C20-and C22-PUFAs from C18 PUFA through a series of desaturation and elongation reactions (Oliva-Teles, 2012).…”
