Spotted stone loach (Triplophysa strauchii), a common fish species in Xinjiang, China, is ecologically pivotal within the local ecosystem; regrettably, human-induced factors like habitat destruction, pollution, and overfishing have gravely imperiled its survival, compounding this dearth of research on morphological disparities among geographically diverse populations. Thus, between April October 2024, 198 specimens were procured from Sayram Lake, Khamusigou Reservoir, Chaiwopu Lake using cage traps gillnets; post-collection, an array metrics meticulously measured, then statistical methods such as one-way analysis variance (ANOVA), principal component (PCA), stepwise discriminant analysis, cluster employed for comprehensive data interrogation. Findings show that, across all sampled populations, mean values total length (X1), body (X2), height (X3), width (X4) population are significantly lower than those Reservoir population; except head length, has variability other traits compared to others. Moreover, significant divergences detected multiple trait ratios populations; PCA yielded five components, cumulatively accounting 77.45% variance, spotlighting key ratios; further validated highly distinctions (p < 0.01), with having highest accuracy; graphically showed populations clustering together while formed separate cluster; had most pronounced divergence traits. This not only provides novel perspectives adaptive evolutionary mechanisms T. strauchii but also serves cornerstone formulating evidence-based conservation management strategies species.

Chronic stress is a critical challenge in fish aquaculture, adversely affecting growth, health, and overall productivity. Among the most significant chronic stressors intensive farming crowding, which triggers release of cortisol, primary hormone fish. Cortisol re-allocates energy away from growth-related processes toward response mechanisms. Consequently, overcrowded often exhibit slower growth rates, impaired skeletal muscle development. Understanding mechanisms underlying crowding their long-term effects, including epigenetic changes, essential for optimizing conditions, enhancing welfare. This study aims to characterize physiological, transcriptomic, epigenomic responses juvenile rainbow trout (Oncorhynchus mykiss) exposed 30 days high stocking densities. Crowding led decreased weight high-density (HD) group. It also resulted elevated cortisol levels, oxidative DNA damage, protein carbonylation muscle. Using RNA-seq, we identified 4,050 differentially expressed genes (DEGs), through whole-genome bisulfite sequencing (WGBS), detected 11,672 methylated (DMGs). Integrative analyses revealed 263 with negative correlation between upregulated expression downregulated methylation, primarily associated autophagy, mitophagy, insulin signaling pathway. Conversely, 299 exhibited reverse trend, mainly linked ATP-dependent chromatin remodeling. offers first detailed exploration molecular stress, integrating RNA-seq WGBS analysis trout, offering valuable information improving aquaculture practices.

ABSTRACT Industrial pollution is a major driver of ecosystem degradation, but it can also act as contemporary evolution. As result intense mining activity during the Revolution, several rivers across southwest England are polluted with high concentrations metals. Despite documented negative impacts ongoing metal pollution, brown trout ( Salmo trutta L.) survive and thrive in many these metal‐impacted rivers. We used population genomics, transcriptomics, burdens to investigate genomic transcriptomic signatures potential tolerance. RADseq analysis six populations (originating from three control rivers) revealed strong genetic substructuring between impacted populations. identified selection at 122 loci, including genes related homeostasis oxidative stress. Trout sampled exhibited significantly higher tissue cadmium, copper, nickel zinc, which remained elevated after 11 days metal‐free water. After depuration, we RNAseq quantify gene expression differences trout, identifying 2042 differentially expressed (DEGs) gill, 311 DEGs liver. Transcriptomic gill were enriched for involved ion transport processes, homeostasis, stress, hypoxia, response xenobiotics. Our findings reveal shared pathways detoxification, stress responses regulation. Overall, our results demonstrate diverse effects shaping both neutral adaptive variation, whilst highlighting role constitutive promoting
