“…A dose-dependent response of dietary ARA inclusion was also observed in some species, such as Japanese flounder 135 and Atlantic cod. 141 In pikeperch (Sander lucioperca), an ARA dietary level of only 3.0% TFA negatively impacted on the egg quality, 142 which was attributed by the authors to the altered ARA/EPA ratio.…”

Throughout the evolution of fish nutrition science, the importance of dietary arachidonic acid (ARA, 20:4n‐6) has been somewhat overlooked, likely due to the polarizing research focus on docosahexaenoic (DHA, 22:6n‐3) and eicosapentaenoic (EPA, 20:5n‐3) acids. Nevertheless, especially during the past two decades, increasing attention has been paid to the requirements and functions of ARA in fish nutrition, and a number of relevant studies have now been conducted on a series of fish species, including both marine and freshwater species. Those studies revealed important and diverse functions of ARA in various physiological processes, such as growth, reproduction, stress resistance, pigmentation, immunity, lipid deposition and bone development. The results of the present review, in addition to providing a state‐of‐the‐art summary of current knowledge, also revealed the complexity of ARA functions in terms of dosages, species, development stage, sex and feeding period, as well as in terms of interaction between ARA and other nutritional or non‐nutritional factors.

“…Although this study can have substantial implications in evaluating the role of fish physiology and/or feeding history in reproductive efficiency, it does not account for the lower feeding efficacy of F1 broodstock in comparison to F0 fish, due to different cognition and preying capacities between the two fish populations [11,12] Anyway, it indicated the potentially lower intrinsic capacity of F1 fish to accumulate ARA in oocytes. This finding was further confirmed when hatchery fish were fed with feed enriched with ARA at the same percentage as was present in live feed [13].…”

“…Aside from ARA, docosahexaenoic (DHA) and eicosapentaenoic acid (EPA) have been considered to affect oocyte quality in maturing fish, which is the reason why broodstock diets are supplemented with DHA-and EPA-rich ingredients, predominantly fish oil [14]. However, even formulated diets rich in DHA and EPA fail to provide satisfactory reproductive performance of hatchery-reared pike-perch broodstock, as shown in the previous study [13]. Moreover, due to competition between DHA, EPA, and ARA for incorporation into membrane phospholipids and/or enzymes involved in eicosanoid synthesis [15,16], DHA/EPA/ARA ratios in diets may be more important than their absolute levels, both for fish growth and reproductive success [17,18].…”

Ratio 3:2:2 was found to be optimal for satisfactory egg and larval quality in Eurasian perch [19], and diets high in marine ingredients do not necessarily meet this requirement [13]. Hence, the application of high-cost diets may unduly increase farming costs, without any advantage to lower-cost, more sustainable diets with a lower inclusion of marine ingredients.…”

This research aimed to evaluate the reproductive potential of hatchery-reared (F1) pike-perch (Sander lucioperca) broodstock fed a commercial diet with low levels of long-chain polyunsaturated fatty acids (Lc-PUFA) and wild (F0) pike-perch broodstock fed forage fish. Reproductive parameters, including pseudogonadosomatic index (PGSI), egg size, latency time, hatching rate, embryo survival, and eggs’ fatty acid (FA) composition, as well as plasma sex hormone, glucose and immunoglobulin levels after hormone injection, were analyzed. The results showed low PGSI (10% in F1 vs. 14% in F0) and embryo survival (24% in F1 vs. 61% in F0) in F1 broodstock, but a satisfactory hatching rate (63% in F1 vs. 78% in F0) and larval size (4.6 mm in F1 vs. 4.7 mm in F0). A low arachidonic acid (ARA) percentage in F1 fish eggs (1.32%), along with increased immunoglobulin levels (17.31 g/L), suggests that immune system activation might have depleted the reserves of ARA in F1 fish, which is the key fatty acid for successful oocyte maturation. We assumed that the administration of more sustainable diets, based on terrestrial plant ingredients, is not inferior to higher-quality diets based on marine ingredients.

“…From the lipid composition perspective, the present study hinted at some fatty acids that were previously identified as contributors to fertility problems in fishes and terrestrial vertebrates if present in higher amounts. For example, the relatively high amounts of α‐linolenic acid (ALA) and arachidonic acid (ARA) in SKR feed could be linked with poor fertilization rate and lower embryo survival (ALA: Jungheim et al ., 2011; Marei et al ., 2010; ARA: Ljubobratović et al ., 2020; Surai et al ., 2000). The generally lower fertilization rate in the dry feed groups compared to the BLW group is commonly found when live feeds and dry feeds are compared (Mandal et al ., 2012; Markovich et al ., 2007).…”

The absence of a controlled diet is unfortunate in a promising model organism for ageing, the turquoise killifish (Nothobranchius furzeri Jubb, 1971). Currently captive N. furzeri are fed bloodworms but it is not known whether this is an optimal diet. Replacing bloodworms with a practical dry feed would reduce diet variability. In the present study, we estimated the nutritional value of the diet ingested by wild fish and determined the fish‐body amino acid profile as a proxy for their nutritional requirements. We compared the performance of fish fed four commercial feeds containing 46%–64% protein to that achieved with bloodworms and that of wild fish. Wild fish target a high‐protein (60%) diet and this is supported by their superior performance on high‐protein diets in captivity. In contrast, feeds for omnivores led to slower growth, lower fecundity and unnatural liver size. In comparison to wild fish, a bloodworm diet led to lower body condition, overfeeding and male liver enlargement. Out of the four dry feeds tested, the fish fed Aller matched wild fish in body condition and liver size, and was comparable to bloodworms in terms of growth and fecundity. A starter feed for carnivorous species appears to be a practical replacement for bloodworms for N. furzeri. The use of dry feeds improved performance in comparison to bloodworms and thus may contribute to reducing response variability and improving research reproducibility in N. furzeri research.
