Oxidative Stress in Mud Crabs Across Bay of Bengal Seasons

Spectrophotometric and FTIR measurements detail the oxidative stress physiology of the edible mud crab Scylla serrata sampled from three coastal zones in Odisha, India. The study analyzes tissue-specific antioxidant enzyme activities and lipid peroxidation levels across summer, rainy, and winter seasons. It correlates these biological responses with habitat variables like water pH, temperature, salinity, and soil calcium, magnesium, and organic carbon loads.

Use Cases

• Analyze correlations between soil Ca, Mg, and organic carbon loads and tissue-specific antioxidant enzyme activities like SOD, catalase, and GPx.
• Model seasonal variation in lipid peroxidation (LPx) levels in crab tissues as a function of water temperature and salinity.
• Compare spatial patterns in total antioxidant levels and ascorbic acid across the Chandipur, Chilika, and Jagatsinghpur coastal zones.
• Investigate the negative correlation between glutathione (GSH) levels and habitat water pH using the reported physiological measurements.

Strengths

• Data includes specific percentage changes in biological responses, such as a 13.23% average increase in antioxidant enzyme activities during dry seasons.
• Measurements cover three distinct seasons with defined temperature ranges: summer (38–42°C), rainy (25–35°C), and winter (12–20°C).
• Study design compares three specific coastal sampling zones along the Bay of Bengal: Chandipur, Chilika, and Jagatsinghpur.

Limitations

• The primary data is embedded in a narrative DOCX file (1.4 MB), not a structured, machine-readable table, complicating direct analysis.
• Sample sizes for crab specimens per season and location are not specified, limiting statistical assessment.
• The dataset title is marked as 'RETRACTED', which may indicate underlying issues with the data or publication.
