Abstract
Heavy metals such as mercury (Hg), lead (Pb), cadmium (Cd), and arsenic
(As) are prevalent contaminants in aquatic ecosystems, originating from
industrial discharge, mining, agricultural runoff, and atmospheric deposition.
These toxic elements pose significant threats to fish reproduction, impacting
both individual organisms and entire populations. This review examines the
mechanisms through which heavy metals affect fish reproductive health,
including endocrine disruption, oxidative stress, and DNA damage. It explores
the implications for fish populations, such as reduced fertility, altered sex
ratios, and decreased offspring survival. Furthermore, the review discusses
current and emerging mitigation strategies to counteract these effects,
emphasizing bioremediation, policy regulations, and the use of advanced
technologies like artificial intelligence for monitoring and managing
contamination. By integrating recent research findings, this paper aims to
provide a comprehensive understanding of the challenges posed by heavy metals
in aquatic environments and to highlight potential solutions to safeguard fish
reproductive health and ensure sustainable aquaculture practices.
