“…It is an adaptation for submerged-buoyant animals, such as fish, not to disturb their center of gravity and thus orientation [ 62 ]. There is a pattern too in this; lipids classes are preferentially catabolized in the following order, from the body reserves: SFA → MUFA → PUFA [ 63 , 64 ]. Barbels raised on average to sub-standard diets had lower essential lipid reserves.…”

Large-bodied, river-migrating, rheophilic fishes (cyprinids) such as barbel Barbus barbus, nase Chondrostoma nasus, asp Leuciscus aspius, and vimba bream Vimba vimba are threatened in major European drainages. This represents the subject of our present study. Their hatchery nutrition prior to river-release is mostly on a hit-and-trial or carp-based diet basis. The study demonstrates an alternative approach to decide optimum nutrition for these conservation-priority and nutritionally data-poor fishes. The study revealed barbel as a central representative species in terms of wild body composition among other native rheophilic cyprinids considered (asp, nase, vimba bream). Taking barbel as a model, the study shows that barbel or rheophilic cyprinids may have carnivorous-like metabolism and higher requirements of S-containing, aromatic, branched-chain amino acids (AAs) than carps. Besides, there are important interactions of AAs and fatty acids (FAs) biosynthesis to consider. Only proper feeding of nutritionally well-selected diets may contribute to river stocking mandates such as steepest growth trajectory (≈less time in captivity), ideal size-at-release, body fitness (≈blend-in with wild conspecifics, predator refuge), better gastrointestinal condition, maximized body reserves of functional nutrients, and retention efficiencies (≈uncompromised physiology). Considering important physiological functions and how AA–FA interactions shape them, hatchery-raised fishes on casually chosen diets may have high chances of physiological, morphological, and behavioral deficits (≈low post-stocking survivability). Based on the observations, optimum nutrient requirements of juvenile (0+ to 1+ age) barbels are suggested. Future efforts may consider barbels as a nutrition model for conservation aquaculture of threatened and data poor rheophilic cyprinids of the region.

“…AS with protein sparing, the concept of omega-3 FAs sparing has emerged too [ 64 , 91 ], with saturated fatty acids (SFA) relative to monounsaturated fatty acids (MUFA) being of central importance. Our present observations might be hinting in this direction too.…”

“…lysine, methionine and tryptophan) in meals, or high levels of SFA in oils, can limit the use of ABP within aquafeeds as these factors can have a negative impact by reducing protein and lipid digestibility 146,147 . Albeit less than 100% digestibility is an expectation for all protein sources and is readily managed—the same should be true for lipid sources high in saturated fats 145 .

The aims of this review are to describe the role of 'blue-food production' (animals, plants and algae harvested from freshwater and marine environments) within a circular bioeconomy, discuss how such a framework can help the sustainability and resilience of aquaculture and to summarise key examples of novel nutrient sources that are emerging in the field of fed-aquaculture species. Aquaculture now provides >50% of the global seafood supply, a share that is expected to increase to at least 60% within the next decade.Aquaculture is an important tool for reducing resource consumption in global protein production and increasing resilience to climate change and other global disruptions (i.e. pandemics, geo-political instability). Importantly, blue foods also provide essential nutrition for a growing human population. Blue foods are helping to help the global goal of 'zero hunger' (United Nation's Sustainable Development Goal 2) while reducing the dependency on finite natural resources but further refinement and new solutions are needed to make the industry more 'circular' and sustainable, particularly with respect to sourcing raw materials for aquafeeds. This review describes the feed resources that are available or may be created within a circular bioeconomy framework, their role within the framework and in aquaculture and ultimately, how these resources contribute to de-risking and establishing a resilient aquaculture production chain.

“…A topic of growing interest and importance, requiring substantial and cohesive R&D effort from all stakeholders. The work from Rombenso et al, 4 comprising a senior and corresponding author from industry, is an opinion piece which makes the case to explore the exploitation of the omega-3 sparing effect, towards producing farmed products with a higher content of beneficial long chain omega-3 fatty acids by optimising their nutritional utilisation. To conclude, another industry-academia joint review effort from Sievers et al 5 provides an in-depth analysis of challenges and opportunities for submerged aquaculture systems, with interesting biological considerations given the diverse nature of fish species, particularly when it comes to swim bladders.…”

The ultimate goal of a literature review is the advancement of the given subject. An objective that is realised not via the reporting of novel findings, observations, data, methods or theories, but via the critical evaluation and logical synthesis of prior studies. By identifying, collecting, reporting, synthesising, comparing and contrasting the findings of published studies in a specific domain, review articles aim to suggest future research opportunities and needs, identify research gaps and, more broadly, provide a state-of-the-art understanding of the research topic to readers. 1
