“…Typically, carbohydrates are the main source of energy metabolism and play a vital role in cell homeostasis under stressful conditions [25]. The overall response in the sugar-based metabolites (Figure 3, pathway A) of the heat-stressed mussels under investigation was a decrease in metabolite concentration after 48 h, followed by an increase at 72 h. Metabolites, such as cellobiose, glucose-1-phosphate, fructose-1.6-biphosphate, galactosamine, arabinose-5-phosphate, arabinose, and xylitol, increased after three days at a constant temperature of 24 • C when compared to control temperature 16 • C. It can be argued that mussels experienced an energy deficit by 72 h due to the presence of heat stress and increased these sugar metabolites to support increased glycolysis functioning (Figure 3, pathway B).…”

Temperature is considered to be a major abiotic factor influencing aquatic life. Marine heatwaves are emerging as threats to sustainable shellfish aquaculture, affecting the farming of New Zealand’s green-lipped mussel [Perna canaliculus (Gmelin, 1791)]. In this study, P. canaliculus were gradually exposed to high-temperature stress, mimicking a five-day marine heatwave event, to better understand the effects of heat stress on the metabolome of mussels. Following liquid chromatography-tandem mass spectrometry analyses of haemolymph samples, key sugar-based metabolites supported energy production via the glycolysis pathway and TCA cycle by 24 h and 48 h of heat stress. Anaerobic metabolism also fulfilled the role of energy production. Antioxidant molecules acted within thermally stressed mussels to mitigate oxidative stress. Purine metabolism supported tissue protection and energy replenishment. Pyrimidine metabolism supported the protection of nucleic acids and protein synthesis. Amino acids ensured balanced intracellular osmolality at 24 h and ammonia detoxification at 48 h. Altogether, this work provides evidence that P. canaliculus has the potential to adapt to heat stress up to 24 °C by regulating its energy metabolism, balancing nucleotide production, and implementing oxidative stress mechanisms over time. The data reported herein can also be used to evaluate the risks of heatwaves and improve mitigation strategies for aquaculture.

“…Copper is a cofactor for various enzymes and a component of hemocyanin [ 3 , 4 , 5 ]. Transition metals including copper can stimulate excessive formation of reactive oxygen species (ROS) and disrupt the balance of oxidation–reduction reactions, causing structural lesions in lipids, proteins, and DNA [ 3 , 6 , 7 , 8 , 9 ]. Unlike copper, nickel cannot generate ROS directly by participating in Fenton and Haber-Weiss redox reactions.…”

The effect of copper and nickel ions on the lipid composition of freshwater mussels Anodonta cygnea was investigated using an aquarium experiment. The contents of the main lipid classes were determined using thin layer chromatography and spectrophotometry, and the fatty acid composition was analysed using gas–liquid chromatography. The results indicated that copper and nickel had different effects on the mussels’ lipid composition, with copper producing less effect on the composition of lipids and fatty acids than nickel. On the first experiment day, excessive copper content in the organism caused oxidative stress and modifications in membrane lipids, which returned to their initial level by the end of the experiment. Nickel accumulated predominantly in gills; however, significant modifications in lipids and fatty acids were seen also in the digestive gland from the first day of the experiment. This indicated the activation of nickel-induced lipid peroxidation processes. Moreover, this study revealed a dose-dependent effect of nickel on lipid composition, which was likely related to the development of compensatory biochemical mechanisms in response to nickel-induced oxidative stress. A comparative study of the lipid composition alteration in mussels in response to copper and nickel action revealed the consequences of the toxic impact of metal ions and the defensive mechanisms that organisms employ to detoxify and remove xenobiotics.
