Even though several studies have reported how stress induces detrimental pathophysiological responses that are linked to increase in disease susceptibility, no study has evaluated the impact of overcrowding on the serum chemistry of Heterobranchus longifilis. This study aimed at evaluating the impact of overcrowding on serum chemistry in Heterobranchus longifilis. Briefly, 30 apparently healthy Heterobranchus longifilis weighing between 1 kg and 1.5 kg were randomly divided into 2 groups of 15 catfish, each designated as groups 1 and 2. Group 1 (control group) was not subjected to stress, while group 2 was subjected to 3 hours of overcrowding in a 120 L plastic water tank at 201 g/L of water. Blood samples were collected from the caudal vein into non-heparinized tubes before stress, immediately after stress and 24 hours after stress. Sera were collected, and serum chemistry and electrolytes were analyzed. At 24 hours after stress, alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, creatinine, uric acid, total bilirubin, conjugated bilirubin, total protein, albumin, total cholesterol, triglyceride, chloride, potassium, and sodium were significantly higher in group 2 compared to the control group. Based on the findings of this study, it was concluded that overcrowding of Heterobranchus longifilis for 3 hours has a significant impact on its health status.
