“…This difference was reflected in the elevated lipid catabolism protein expression levels in carnivorous fish and increased glycolysis protein levels in omnivorous fish. Tinca tinca , although primarily a carnivorous feeder with optimal dietary lipid, carbohydrate, and protein requirements of around 11%, 19%, and 48%, respectively ( González-Rodríguez et al, 2014 ), displayed a high hypoxia tolerance similar to some omnivorous species, suggesting unique adaptation. In addition, this species demonstrated a higher capacity for glucose breakdown compared to fatty acid catabolism.…”

Hypoxia is a common environmental stress factor in aquatic organisms, which varies among fish species. However, the mechanisms underlying the ability of fish species to tolerate hypoxia are not well known. Here, we showed that hypoxia response in different fish species was affected by lipid catabolism and preference for lipid or carbohydrate energy sources. Activation of biochemical lipid catabolism through peroxisome proliferator-activated receptor alpha (Pparα) or increasing mitochondrial fat oxidation in tilapia decreased tolerance to acute hypoxia by increasing oxygen consumption and oxidative damage and reducing carbohydrate catabolism as an energy source. Conversely, lipid catabolism inhibition by suppressing entry of lipids into mitochondria in tilapia or individually knocking out three key genes of lipid catabolism in zebrafish increased tolerance to acute hypoxia by decreasing oxygen consumption and oxidative damage and promoting carbohydrate catabolism. However, anaerobic glycolysis suppression eliminated lipid catabolism inhibition-promoted hypoxia tolerance in adipose triglyceride lipase ( atgl ) mutant zebrafish. Using 14 fish species with different trophic levels and taxonomic status, the fish preferentially using lipids for energy were more intolerant to acute hypoxia than those preferentially using carbohydrates. Our study shows that hypoxia tolerance in fish depends on catabolic preference for lipids or carbohydrates, which can be modified by regulating lipid catabolism.

“…The development of intensification techniques is necessary to promote and consolidate tench production, and establishing rearing procedures under controlled conditions is essential to set up adequate feeding in early growth phases. As a specific diet is essential to face nutritional studies, González-Rodríguez et al [ 34 ] and García et al [ 31 ] proposed a practical diet for juvenile tench which allowed for good juvenile survival and growth performance. Later, Sáez-Royuela et al [ 35 ] determined that an 8.5% dietary lipid content (2% of cod liver oil) should be present in the formulation.…”

Tench (Tinca tinca L.) plays a key role in the diversification of inland aquaculture, but its culture is mainly based on extensive culture systems with usually low and unpredictable yields. Rearing procedures under controlled conditions are essential to promote and consolidate tench production, and it is necessary to set up adequate feeding in early growth phases. Fish oil (FO) is currently the main source of lipids in aquafeeds, but considering the stagnation of smaller pelagic fisheries, alternative oils should be addressed. In a ninety-day experiment, the effects of partial and total replacement of FO with camelina oil (CO) on juvenile tench growth performance and whole-body composition were evaluated. Six isonitrogenous and isolipidic diets with different levels of CO were tested: 0% (control), 20%, 40%, 60%, 80%, and 100%. The survival rate was 100%, and no significant differences in growth performance (total length, weight, specific growth rate, feed conversion ratio, and biomass gain) were found. The lipid content in whole-body juveniles was significantly lower when juveniles were fed diets containing 40% and higher levels of CO than those fed the control diet whereas linolenic acid content was significantly higher. No differences in ΣSFA, ΣMUFA, ΣPUFA, Σn − 3, or Σn − 6 whole-body content were found. The nutritional indices ΣPUFA/ΣSFA and Σn − 6/Σn − 3 showed a linear increase trend with dietary CO inclusion whereas the EPA + DHA showed an opposite tendency. Compared to the control diet, EPA + DHA content (g kg−1) was significantly lower in juvenile tench fed a 100% CO diet, and Σn − 6/Σn − 3 was significantly higher in juvenile tench fed 80% and 100% CO diets. Overall, the results indicate that the total replacement of FO with CO in diets is feasible without negative effects on growth performance whereas the nutritional quality of juvenile tench was unaffected with a maximum replacement of 80%.

“…The availability of a specific diet is essential to face nutritional studies. For this reason, García et al (2015) proposed a fish meal‐based practical diet for juvenile tench and later González‐Rodríguez et al (2014) estimated the protein requirements between 48 and 52%. In both studies, good survival and growth performance were achieved.…”

“…In the search of alternative protein sources, plants are increasingly incorporated to satisfy the growing demands of the aquafeed industry (Malcorps et al, 2019). Between plant protein sources, pea protein concentrate (PPC) is a promising alternative to FM (Gatlin et al, 2007;Hartviksen et al, 2014). This product is obtained using a dry fractionation process, which employs milling and further air classification to separate smaller protein-rich from larger fibre and starch-rich granules (Pelgrom et al, 2013;Schutyser et al, 2015).…”

Aquaculture is currently one of the fastest growing food-production sectors in the world and plays a key role in achieving many of United Nations Sustainable Development Goals in 2030 (FAO, 2020).Although agriculture and livestock farming are less diversified in terms of the number of species and culture systems than aquaculture, it is officially recognized that the development of diversification strategies is essential to improve the culture of aquatic species (FAO, 2017(FAO, , 2019. Among freshwater fish, tench (Tinca tinca L.) is considered one of the most promising species for the development of inland culture (Kujawa et al., 2011). This cyprinid is highly appreciated in many European countries, mainly for its gastronomic quality but also as an attractive sport fishing species (
