Assessing the interplay between trophic index (TRIX), and environmental health from an aquaculture perspective

<span style="caret-color: rgba(0, 0, 0, 0.87); color: rgba(0, 0, 0, 0.87); font-family: &quot;Noto Sans&quot;, -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Oxygen-Sans, Ubuntu, Cantarell, &quot;Helvetica Neue&quot;, sans-serif; font-size: 14px;">The Trophic Index (TRIX) serves as a comprehensive metric for evaluating eutrophication in aquatic ecosystems by integrating key water quality parameters, including chlorophyll-a, dissolved inorganic nitrogen, total phosphorus, and oxygen saturation deviation. Elevated TRIX values typically signal increased nutrient loading, often linked to anthropogenic activities such as agricultural runoff, wastewater discharge, and aquaculture effluents. This study investigates the interplay between TRIX values, water quality, and the environmental health of aquaculture sites along the Turkish coasts. Through multi-year TRIX monitoring at two designated aquaculture zones in the Aegean and Mediterranean Seas, findings reveal that TRIX values remained below the critical threshold for eutrophication risk, indicating stable environmental conditions. The study underscores the necessity of continuous TRIX-based monitoring to assess trophic dynamics, ensure sustainable aquaculture practices, and mitigate ecological risks. The results contribute to the broader discourse on balancing aquaculture productivity with marine ecosystem health through informed nutrient management strategies.</span><br>
