Metabolic responses to short starvation and re-feeding in rainbow trout (Oncorhynchus mykiss)

Changes in fatty acids, blood biochemistry and mRNA expressions of genes involved in polyunsaturated fatty acid metabolism in brown trout (Salmo trutta) during starvation and refeeding

“…In fishes, lipids are a major source of energy for fundamental metabolism during starvation periods and proteins are broken down if needed (Cho, 2005; Li et al., 2018). It has been well‐documented that plasma lipid levels are differently affected by starvation in fish because of the complex interactions among the environment, species, age and feeding history prior to food deprivation (Azodi et al., 2015; Dar et al., 2018; Eslamloo et al., 2017; Li et al., 2018; Rossi et al., 2015). Few studies on teleosts have described that starvation upregulates or downregulates gene expressions involved in lipid metabolism, owing to the effect of the factors listed above (Martin et al., 2010; Qian et al., 2016; Salem et al., 2007).…”

Short-term starvation in silver pomfret (Pampus argenteus): molecular effects on lipid mobilization and utilization

“…During short‐term starvation, lipids provide an energy source for bodily metabolic activities and maintaining overall homoeostasis of fish. Previous studies have demonstrated that starvation results in a decrease of tissue lipid content, changes in fatty acid composition and alterations in circulating lipid metabolites (Jezierska, Hazel & Gerking ; Black & Love ; Black & Skinner ; Segner, Dölle & Böhm ; Pérez‐Jiménez, Guedes, Morales & Olivateles ; McCue ; Tian, Wen, Zeng, Jiang, Wu, Liu & Yang ; Azodi, Ebrahimi, Motaghi & Morshedi ). Nevertheless, how starvation affects key aspects of lipid metabolism, such as lipid mobilization and utilization, is not fully understood.…”

Effects of dietary xylooligosaccharide on growth and feeding performance, body composition and physiological responses of sobaity seabream ( Sparidentex hasta ) juvenile

“…The blood samples for haematological factors and serum biochemical assays were drawn from the caudal vein of the individual fish. For serum, the whole blood was collected in a syringe, allowed to clot in microtubes at room temperature, stored in a refrigerator and (4 hr at 4°C) and then serum was harvested by centrifuging at 3,000 × g for 10 min at 4°C (Azodi, Ebrahimi, Motaghi, & Morshedi, ). All serum samples were preserved at −20°C prior to analysis.…”
