Muscle Proteomic Dataset of A Threatened Indian walking catfish, Clarias magur (Hamilton 1822) Exposed to Thermal Stress

This Data Descriptor presents a comprehensive LC-MS/MS-based muscle proteome dataset for Clarias magur subjected to sustained sub-lethal thermal stress. Fish were maintained at a control temperature of 26 °C or gradually warmed at a rate of 1 °C per day until reaching 37 °C, which was sustained for 60 days. Muscle samples were collected, proteins were extracted, digested with trypsin, and analyzed using a Waters SYNAPT G2-Si Q-TOF mass spectrometer. Resulting peptide spectra were searched against the Danio rerio Swiss-Prot UniProt database due to limited proteome resources for C. magur. The dataset includes raw mass spectral files, protein and peptide tables, sample metadata, water-quality logs, and processing files. These records are publicly available via PRIDE and are intended to support future studies on thermal tolerance in aquaculture species here the sole objective is to provide a transparent and reusable thermal proteome resource.
