Toxic Effects of Ammonia Exposure on Growth and Hematological Response of Clarias Batrachus (linneaeus, 1758)
Summary
Researchers investigated the effects of ammonia exposure on the catfish Clarias batrachus, finding that increasing ammonia concentrations over three months significantly impaired growth performance and altered hematological parameters.
In aquatic environments, ammonia nitrogen is the primary pollutant that depletes oxygen.In this study effects of ammonia exposure on growth and hematological parameters of Clarias batrachus was investigated.Fish with a mean initial total length of 13.33 ±1.08, 13.46±1.80,13.53±0.94,13.40±1.94,and 14.11±0.69cm, and with a body weight of 22.36±5.84,24.36±9.93,23.38±5.17,23.11±9.36 and 25.66±6.00g were exposed for 3 months with ammonia concentrations (0, 0.25, 0.50, 0.75 and 1.00 mg/L), in T-o, T-I, T-II, T-III, and T-IV, respectively.A significant decrease was observed in mean values of growth, condition factor and various hematological parameters such as White Blood Cell (WBC), Hemoglobin (Hb), Red Blood Cell (RBC), Hematocrit (HCT), Platelets (PLT), Monocyte (Mon), Lymphocyte (LYM), and Mean Platelet Volume (MPV), while other hematological parameters including Mean Corpuscular Hemoglobin (MCH), Mean Corpuscular Hemoglobin Concentration (MCHC), Mean Corpuscular Volume (MCV) and Red Cell Distribution Width Standard Deviation (RDW-SD) were significantly increased (P< 0.05) as determined by Duncan's multiple range test.

Toxic Effects on Bioaccumulation, Hematological Parameters, Oxidative Stress, Immune Responses and Tissue Structure in Fish Exposed to Ammonia Nitrogen: A Review
This review summarizes how ammonia nitrogen pollution in aquatic environments affects fish health, including damage to blood, organs, immune function, and tissue structure. Researchers found that ammonia exposure triggers oxidative stress and bioaccumulation in fish, with toxic effects varying by species and developmental stage. The study highlights the importance of monitoring ammonia levels in waterways to protect aquatic ecosystems and the food chain.
Oxidative Stress and Immunopathological Alterations of Clarias gariepinus Exposed to Monocyclic Aromatic Hydrocarbons (BTX)

Combined effects of water salinity and ammonia exposure on the antioxidative status, serum biochemistry, and immunity of Nile tilapia (Oreochromis niloticus)
Researchers tested how combinations of saltwater and ammonia affect the health of Nile tilapia and found that fish raised in high-salinity water with continuous ammonia exposure showed the worst outcomes, including reduced growth, weakened immunity, and tissue damage to gills and intestines. The study suggests moderate brackish water (5–10 ppt) is manageable but high ammonia makes it harmful.
Investigations of hemato-biochemical and histopathological parameters, and growth performance of walking catfish (Clarias batrachus) exposed to PET and LDPE microplastics
Researchers exposed walking catfish to PET and LDPE microplastics for 60 days and observed significant changes in blood parameters, including decreased red blood cells and increased white blood cells. Tissue damage was found in the liver and gills, and fish growth was reduced compared to unexposed groups. The study suggests that bottom-dwelling fish species may be particularly vulnerable to microplastic contamination in their habitat.
