“…When compared with the CTRL, all diets promoted EPA+DHA gain, which resulted in a significant increase in fish whole body EPA+DHA content. Still, both fatty acids were metabolized at whole body level, as suggested by their correlation line below the equity line (Figure 1), whilst a selective deposition and retention of these FA was noted in muscle as previously reported in marine fish species, such as Atlantic salmon (Bell et al, 2002;Bell et al, 2003), turbot (Regost et al, 2003), Senegalese sole (Pereira et al, 2019), gilthead seabream (Fountoulaki et al, 2009) and European sea bass (Montero et al, 2005;Marques et al, 2022). In the present study, there is a trend for a higher retention of DHA, as compared to EPA (Figure 2B), which could be due to a higher beta-oxidation of EPA when compared to DHA.…”

“…The partial or total FO replacement by vegetable oils (VO) in fish diets has been thoroughly evaluated (Turchini et al, 2010;Torrecillas et al, 2017). Many studies have shown that it is feasible to partially replace FO by VO in diets for both freshwater and marine fish species without affecting feed utilization and growth (Turchini et al, 2009;Dikel et al, 2013;Pereira et al, 2019). However, others studies have reported negative effects on fish health and fillet nutritional value due to the low levels of n-3 LC-PUFA and the imbalance of n-3 PUFA to n-6 PUFA (Glencross, 2009;Nasopoulou and Zabetakis, 2012).…”

IntroductionIn order to ensure lipid quality of cultured fish and an environmentally sustainable production, new alternative sources of EPA and DHA are needed to replace traditional lipid sources, such as fish oil.MethodsDifferent combinations of alternative marine lipid sources rich in n-3 LC-PUFA available in the market were herein evaluated to replace traditional fish oil (sardine oil) in diets for European sea bass (Dicentrarchus labrax). A commercial-type diet (CTRL), containing 1.6% of EPA + DHA, 5% sardine oil and 8% rapeseed oil was used as a negative control. Another diet (SARDINE) formulated with 8.5% sardine oil, 4.5% rapeseed oil and 2.5% EPA + DHA was used as the positive control. Three experimental diets were formulated to completely replace sardine oil with alternative sources, targeting approximately the same EPA + DHA level as the positive control: the SALMON diet contained 9.9% salmon by-product oil mixed with 3.1% of an algal oil rich in EPA and DHA, while the ALGARAPE and the ALGASOY diets included 4.4% of the algal oil and 8.6% of either rapeseed or soybean oil, respectively. A sixth diet (ALGABLEND) was formulated to partially replace sardine oil with salmon by-product oil and rapeseed oil, balanced with 2% of algae biomass. The experimental diets were hand-fed to 118 g fish for 54 days. ResultsAll diets were well-accepted by fish and no significant differences were found in feed efficiency, growth performance, somatic indexes or whole body composition among treatments. At the end of the trial, regardless the dietary EPA + DHA level, all fillets contained more than 250 mg of EPA + DHA per 100 g fresh weight, meeting EFSA recommendations for cardiovascular risk prevention for European adults (> 250 mg day -1). DiscussionOverall, this study demonstrated that combining expensive sources of n-3 LC PUFA (Veramaris® or Algaessence Feed™ with low-priced sustainable oils (salmon by-products oil or vegetable oils) allows fortifying European sea bass flesh with EPA and DHA, without major textural changes. This approach is a successful strategy for mitigating the negative effects associated with the high inclusion of vegetable oils. However, the retention of n-3 LC-PUFA in muscle was not significantly increased, suggesting that there is a maximum dietary threshold beyond which β-oxidation might be promoted, and hence there is no advantage in increasing the dietary level of these fatty acids in European sea bass diets.

“…Moreover, the digestive ability is different for the different growth stages of fish species. The significant differences on the nutrients demand have been observed in the different growth stages of fish species (Alam et al, 2020;Busti et al, 2020;Canosa and Bertucci, 2020;Lopes et al, 2021;Pereira et al, 2019).…”

In this study, the effect of different lipid levels (6.6, 10.56, 15.43, 18.91, 22.52 and 26.91%) on the body composition, growth performance and lipid deposition was investigated in the post-larval coho salmon (Oncorhynchus kisutch). The results showed that the optimum lipid level for post-larval coho salmon was 15.8% based on the Specific Growth Ratio (SGR). Moreover, 15.43, 18.91, 22.52 and 26.91% lipid levels significantly elevated the content of crude lipid in fish. However, the moisture, ash and crude protein was not significantly influenced by various lipid levels. The lipid levels of 18.91, 22.52 and 26.91% significantly elevated the content of TC, TG and NEFA, whereas significantly decreased the activity of FAS, ACC and ACL in the liver of coho salmon. In addition, the higher lipid levels significantly increased the activity of HL and LPL in liver. The total content of Saturated Fatty Acids (SFA) was increased but that of Polyunsaturated Fatty Acids (PUFA) was decreased by 18.91, 22.52 and 26.91% lipid levels. In all, the appropriate lipid levels had positive effects on the growth performance and hepatic lipid deposition of the post-larval coho salmon. Our results will be beneficial for optimizing the use of lipid in the diets of Coho salmon.
