“…In the last few decades, the aquafeed industry has gone through major changes in diet formulation to enhance fish performance in culture systems and to promote sustainability of the growing aquaculture industry [1,2,3]. Increasing inclusion of plant-derived ingredients in lieu of marine-derived feedstuff in finfish diets is part of the initiatives to reduce aquaculture’s dependence on marine resources.…”

Atlantic salmon (Salmo salar) is a carnivorous fish species whose productive performance tends to be suboptimal when fed low-cost carbohydrate rich meals. It is of interest to study the dynamics of gut microbiota communities in salmonids fed high carbohydrate diets since gut microbes are referred to as key players that influence the metabolism and physiology of the host. A study was conducted to determine the effect of feeding a high carbohydrate diet to Atlantic salmon in gut microbiota communities. A medium carbohydrate (15% wheat starch)/medium protein (MC/MP) diet or a high carbohydrate (30% wheat starch)/low protein (HC/LP) diet was fed to triplicate tanks (28 fish each) during four weeks. We conducted an in-depth characterization of the distal intestine digesta microbiota using high-throughput sequencing of the V4 region of the 16S rRNA gene. Firmicutes, Actinobacteria and Proteobacteria were the major phyla determined in either experimental group. Phylum Planctomycetes, class Planctomycetia, order Planctomycetales and genus Lactococcus were significantly more abundant in fish fed the HC/LP diet compared with fish fed the MC/MP diet. Our study suggests feeding a carbohydrate rich meal to salmon exerts a low impact on the structure of gut microbial communities, affecting mostly low-abundance bacteria capable of metabolizing anaerobically carbohydrates as a major energy-yielding substrate.

“…F isheries and aquaculture represent an important source of food, nutrition and employment for millions of people in the industrialised nations as well as many of those who struggle to maintain reasonable livelihoods in resource-limited countries (Al-Rasheed et al, 2018Klinger et al, 2017). The industry has become the fastest-growing agricultural industry due to recent advances in the genetic, nutritional as well as cultural and management systems (Small et al, 2016). The expansion of the aquaculture sector occasioned by the genetic improvements, especially in the production of hybrid fishes with improved desirable traits like flesh quality has made investments in the sector more profitable, hence the increase in demands for fish products (Guillen et al, 2019;Supartini and Yagi, 2018).…”

This study investigated the biochemical composition of a hybrid, crossbred between Pangasianodon hypophthalmus (PH) (♀) and Pangasius nasutus (PN) (♂), denoted as hybrid PH×PN, in comparison to its parents' species in terms of proximate compositions, fatty acid, and amino acid profiles. The results revealed that the biochemical composition of hybrid PH×PN was comparable with either one of its parents' species. The crude lipid and total saturated fatty acids (SFAs) were significantly higher in hybrid PH×PN and P. hypophthalmus. Also, crude protein and docosahexaenoic acid (22:6n-3, DHA) were higher in the hybrid PH×PN and P. nasutus. However, there were no significant differences recorded between the hybrid and its parents for omega-3 (n-3PUFA), total polyunsaturated fatty acids (PUFAs), and eicosapentaenoic acid (C20:5n-3, EPA) and (C22:5n-3, EPA). Likewise, the total essential amino acids (EAAs) was significantly higher in hybrid PH×PN and P. nasutus. In summary, certain components did not deviate much from either of their parents' species or even enhanced in the hybrid compared to P. nasutus. Therefore, the production of this hybrid could be an alternative to meet the market demand for P. nasutus.
