Hematological profiles have been extensively used as a biomarker of fish, but such information is still limited for juvenile fish in mangrove forests of Thailand. The current study aimed to investigate the morphological characteristics of blood cells in five ecologically important estuarine fish species from the Estuary Pranburi River (EPR), Thailand: Ambassis kopsii, Chanos chanos, Chelon subviridis, Dermogenys pusilla, and Leiognathus decorus. We determined erythrocyte size of these species, demonstrating that C. subviridis and D. pusilla have eclipse erythrocytes. Three kinds of leukocyte including lymphocyte, monocyte, and neutrophil were also identified in this study. Lymphocytes were found in all species whilst monocytes and neutrophils were identified only in C. chanos, C. subviridi, and D. pusilla. Our hematological analysis has added new information to the literature and will help future hematology-based health monitoring of fish in Thailand and other countries.
