Objective: To monitor the water quality parameters and climatic impact on the health condition\udof the fish through pathology study of Marine catfish spleen using Melano-macrophage centers\ud(MMCs) aggregation as a biomarker Marine catfishes along the parangipettai coast of Tamil Nadu.\udMethods: Replicate samples were done for all the seasons along the coast. Condition factor (K)\udand Histopathology technique, were used to evaluate the condition. Results: The result revealed\udthe Condition factor (K) of fish was minimum in winter 1.0874 and maximum in summer 1.6726.\udHistology show the number of MMCs aggregation in spleen 59.5 暲8.3 MMCs/mm2 was observed in\udat post monsoon and 2-5 MMCs/mm2 in summer. Anova shows significantly different at P<0.05.\udThe MMCs aggregation excited 30/mm2 when the water temperature is below 22曟and reaches\udmaximum at temperatures of below 20 曟. The MMCs were correlated with water temperature\udshows positive correlation mean drop in water temperature may also reason for MMCs aggregation\udin spleen. Conclusion: The rise in temperature causes effect in health of the fish which was\udindicated in condition factor and MMCs aggregation. Animals are vulnerable to disease due to\udlowering of temperature and other environmental conditions. The MMCs aggregation can be used\udas bio-indicators for environmental
