Studies on the Prevalence Rate of Neoplastic Growth in Fish Johniuss Dussumieri (Valenciennes, 1833) of Karachi Coast Due to Polluted Sea Environment

Abstract

Background: With the growing concern over the impacts of environmental pollution on marine life, this study addresses the critical issue of neoplastic growth in fish populations. The increasing prevalence of tumors in fish due to contaminated marine environments has raised alarms about ecosystem health and public health implications. Objective: The primary objective of this research was to assess the prevalence and seasonal variation of neoplastic growth in fish populations, particularly focusing on the impact of environmental pollution. Methods: Fish specimens were collected from various markets and examined for neoplastic growth. The study employed observational techniques, statistical analyses including ANOVA and Duncan's Multiple Range Test, and assessed seasonal variations from January 2019 to December 2022. Results: A total of 2,373 fish were examined, with 193 cases of neoplastic growth identified, indicating a substantial prevalence of tumors. The statistical analysis revealed significant variations in tumor prevalence, with a notable correlation to environmental factors. Conclusion: The study concludes that environmental pollution significantly impacts the prevalence of neoplastic growth in fish populations. This has profound implications for marine ecology and public health, emphasizing the need for effective environmental management and pollution control measures.
