“…For instance, salinity stress alters the oxidative phosphorylation pathway in the gills of Eriocheir sinensis, leading to changes in energy-metabolism homeostasis [51]. Similarly, L. vannamei responded to nitrite stress by upregulating genes related to oxidative phosphorylation, resulting in enhanced energy metabolism in gills [52]. Chronic hypoxic stress affects the oxidative phosphorylation pathway in the gills of Macrobrachium nipponense, potentially coping with increased energy demand [53].…”

Stocking density is a crucial factor affecting productivity in aquaculture, and high stocking density is a stressor for aquatic animals. In this study, we aimed to investigate the effects of stocking densities on oxidative stress and energy metabolism in the gills of Cherax quadricarinatus under rice-crayfish farming. The C. quadricarinatus were reared at low density (LD), medium density (MD), and high density (HD) for 90 days. The results showed that the superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and malondialdehyde (MDA) levels were higher in the HD group than those in the LD group. Transcriptomic analysis revealed 1944 upregulated and 1157 downregulated genes in the gills of the HD group compared to the LD group. Gene ontology (GO) enrichment analysis indicated that these differentially expressed genes (DEGs) were significantly associated with ATP metabolism. KEGG (Kyoto Encyclopedia of Genes and Genomes) analysis also showed that high stocking density resulted in the dysregulation of oxidative phosphorylation. Furthermore, high stocking density upregulated six lipid metabolism-related pathways. Overall, our findings, despite the limited number of samples, suggested that high stocking density led to oxidative stress and dysregulation of energy metabolism in the gills of C. quadricarinatus under rice–crayfish co-culture. Alteration in energy metabolism may be an adaptive response to adverse farming conditions.
