The transformation of land use for ecotourism can yield mixed impacts. To ensure ecological integrity, monitoring tools like bioindicators such as fish species sensitive to environmental stressors are vital for assessing ecosystem health and informing conservation strategies. This study evaluates the health of aquatic conservation areas in East Java, Indonesia, through analyses of fish hematology and water quality parameters. Selected sites such as Iwak Kali, Boonpring, and Badherbank were chosen for their ecological and economic significance as well as the challenges posed by pollution. The aim was to assess ecological health by using hematological profiles and water quality indicators. Fish species including Tawes, Nilem, and Wader Cakul were sampled, and hematological tests measured erythrocytes, leukocytes, hemoglobin, and other immune parameters. Simultaneously, water samples were tested for dissolved oxygen, ammonia, nitrate, and other indicators of water quality. The findings revealed notable differences in fish hematology and water quality across the sites, with certain fish species demonstrating greater resilience to environmental stressors. High pollution levels detected at Badher Bank indicate a need for focused conservation interventions. In conclusion, this study demonstrates that integrating fish hematology with water quality monitoring provides a comprehensive approach to managing aquatic conservation areas, promoting both ecological sustainability and community involvement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Summary<\/jats:title>\n
