Understanding and connecting the impact of anthropogenic activities on mangrove food webs is a research challenge. Has research on the subject been able to find answers using stable isotopes? The present opinion paper analyzed the utility of stable isotopes in tracing the impact of anthropogenic activities on mangrove food webs and if the research questions raised could be answered using these chemical markers. Representative research papers (16) focused on the use of stable isotopes (δC, δN, δS, δH, δD,206Pb/207Pb, and 208Pb/207Pb) to evaluate the effect of anthropogenic activities (Sewage discharge, timber harvesting-deforestation, metallurgical activities, hydrological disruption, aquaculture ponds, and urban development) on mangrove food webs were selected.

- Mangroves are crucial ecosystems along tropical and subtropical coastlines, but human activities harm their habitat quality and affect fish communities.
- The study compared fish communities from three mangrove systems with varying levels of human impact, revealing that moderate intervention resulted in the highest fish abundance, while high intervention led to decreased diversity and abundance.
- Findings indicated that anthropogenic activities alter the trophic structure and diversity of mangrove fish communities, suggesting that human actions disrupt energy flow and resource availability in these coastal ecosystems.
