This research proposes an environmental quality indicator to detect, predict and scientifically evaluate the environmental impact generated by chemical substances within the pollutant group of nonsteroidal anti-inflammatory drugs (NSAIDs) that are categorized as emerging contaminants (ECs) with endocrine disruptive action. The present study was carried out in two coastal lagoons affected by wastewater produced by urban and rural settlements in the states of Colima and Jalisco. Four pharmaceutical compounds were analyzed: diclofenac, ibuprofen, ketorolac and naproxen. The muscle tissues of 14 fish species were analyzed; all had measurable concentrations of the four contaminants. The presence of the ECs was confirmed in all the samples collected. The bioaccumulative potential risk (BPR) of the ECs is estimated by calculating the environmental risk factors and the potential risks to human health, evaluating the concentration and assessing the risk involved in the incorporation of the pollutants into the environment. The BPR indicates the potential impact of NSAIDs on the ecology of these coastal lagoons, and predicts whether a contaminant is likely to act and persist in the environment and bioaccumulate in organisms. Additionally, it estimates the possibility of contamination and risks to human health caused by residues of the chemical contaminants.

Reproductive biology is fundamental for understanding fish population dynamics and for guiding fisheries management and aquaculture practices. Key reproductive and fishery-related variables such as catch size, age at maturity, spawning season, aggregation behavior, and the implementation of seasonal closures are critical to ensuring fish population sustainability. Snappers have been targeted for commercial aquaculture development due to their plasticity and ability to adapt to captive conditions. In Mexico, reproductive biology information on snappers remains fragmented and largely species-specific along both Pacific and Gulf coasts. This review reveals a lack of integrated perspective on snappers’ reproductive biology and identifies key knowledge gaps that may limit the development of effective conservation measures and aquaculture strategies. The absence of species-specific regulations for many snapper species along the Mexican Pacific coast reflects limited biological information and restricts the development of effective management policies. Increasing catch rates may indicate overexploitation, highlighting the need for targeted research to address existing information gaps and support effective conservation strategies for snapper populations. This review synthesizes available information on snapper reproductive biology and discusses how these traits can inform broodstock management, spawning control, and seed production in snappers from the Mexican coastal regions.
