“…In fish, the phospholipid composition of the cell membrane was altered by temperature (Farkas et al, 2001;Grim et al, 2010). In rainbow trout (Oncorhynchus mykiss), the levels of PC and lysophosphatidylcholine (LysoPC) in the liver were reduced after exposure to high temperatures (Li et al, 2022). Here, most of the glycerophospholipids containing polyunsaturated fatty acids (PUFAs), such as PC 18:5-22:6 and PE 22:4e-20:5, were downregulated in the 19°C group (Supplementary Table A .5.).…”

The effect of thermal changes on the physiology and behavior of fish is a major research focus in the face of ongoing global warming. There is little information about the effects of temperature increase on fish in the wild. However, the consequences of temperature increase on fish in controlled laboratory conditions can provide insights into what can be expected in the wild. Triplophysa bleekeri, a high-plateau fish, exhibits high sensitivity to high temperatures, suggesting it to be a good model to investigate the impact of temperature increase on fish. In this study, we analyzed the effect of gradual temperature increase on transcriptional and metabolic levels of T. bleekeri subjected to a gradual temperature change of 0.5°C/day until temperatures of 10°C, 13°C, 16°C, and 19°C were reached. Transcriptomics results of the liver, gut, spleen, and trunk kidney showed that metabolic pathways are widely involved in the response to increased temperatures in T. bleekeri. Lipidomics results further indicated that the lipid composition was altered by increased temperatures, and three lipids (PC 14:0e/22:1, PC 18:0e/22:5, and TAG 14:3-21:2-21:2) were identified as potential biomarkers of heat stress in T. bleekeri. Moreover, a decline in unsaturated fatty acid levels was observed in T. bleekeri under high temperatures. These results suggest that high temperatures modify the metabolomic pathways. Overall, our results help improve the understanding of physiological responses in fish to increased temperatures, and provide valuable information predicting the consequences of global warming on fish.

“…Under these conditions, the mechanism involved increases free radical production and reduces tissue damage which could be attenuated by SeNP supplementation [ 102 ]. Furthermore, a recent study found that SeNP supplementation alleviated heat stress and improved thermal tolerance in rainbow trout through upregulation of GPx and CAT activities and activation of glutamate-glutamine pathways linked to reduced ROS production and inflammation [ 103 ]. Microscopically, the phospholipid membrane of rainbow trout was more integral due to SeNP-induced mitigation of oxidative damage.…”

Dietary selenium (Se) intake within the physiological range is critical to maintain various biological functions, including antioxidant defence, redox homeostasis, growth, reproduction, immunity, and thyroid hormone production. Chemical forms of dietary Se are diverse, including organic Se (selenomethionine, selenocysteine, and selenium-methyl-selenocysteine) and inorganic Se (selenate and selenite). Previous studies have largely investigated and compared the health impacts of dietary Se on agricultural stock and humans, where dietary Se has shown various benefits, including enhanced growth performance, immune functions, and nutritional quality of meats, with reduced oxidative stress and inflammation, and finally enhanced thyroid health and fertility in humans. The emergence of nanoparticles presents a novel and innovative technology. Notably, Se in the form of nanoparticles (SeNPs) has lower toxicity, higher bioavailability, lower excretion in animals, and is linked to more powerful and superior biological activities (at a comparable Se dose) than traditional chemical forms of dietary Se. As a result, the development of tailored SeNPs for their use in intensive agriculture and as candidate for therapeutic drugs for human pathologies is now being actively explored. This review highlights the biological impacts of SeNPs on growth and reproductive performances, their role in modulating heat and oxidative stress and inflammation and the varying modes of synthesis of SeNPs.

BackgroundTemperature, which affects numerous physiological processes, has been described as the 'main ecological factor' for fish. The aim of this modelling study is to explore the impact of climate‐induced temperature changes on fish fillet quality and shelf life.ResultsThe obtained results showed that temperature stress in rainbow trout effects ash and moisture and inhibits myofibril fragmentation in fillet. However, with the increase in temperature, there was a decrease in the total amount of saturated fatty acids (∑SFA) and significant increases in the total amount of omega 3 (∑n3) and 22:6n‐3 (DHA). It was determined that temperature increase had a negative effect on color, texture, water holding capacity, water activity, pH, lactic acid and glycogen levels in fillets, while it had a positive effect on the delay of microbial spoilage especially in cold storage.ConclusionThis study suggest that the effects of climate change on products quality and shelf life infish take specific research community attention. However, it also highlights knowledge gaps to guide future research in this emerging field.This article is protected by copyright. All rights reserved.
