Potential biomarker genes for crowding stress in maraena whitefish Coregonus lavaretus

ABSTRACT: Stress represents a major factor negatively affecting fish welfare in aquaculture. The objective of the present study was to identify and evaluate informative indicators for the welfare and particular health status of maraena whitefish (Coregonus maraena) farmed at four different stocking densities. Transcriptome profiling revealed that numerous stress-related signaling pathways were activated in liver and kidney under ED and HD conditions, such as ERK/MAPK, mTOR, glucocorticoid receptor, SAPK/JNK and JAK/Stat signalling, as well as p38 and p53 signalling. Moreover, several stress-relevant effector pathways were found to be overexpressed including glycolysis and glycogen degradation. Strikingly, a high number of upregulated genes in kidney and in liver of fish kept at HD (compared to MD fi
