“…PAHs enter the aquatic environment primarily via an oil spill, riverine drainage, and urban and industrial effluents [ 29 , 30 , 61 , 62 ]. The 2–3 ringed low molecular weight (LMW) PAHs are more likely to persist in the water after being released, where they can be ingested or breathed in by aquatic organisms [ 29 , 30 ]. The high molecular weight (HMW) PAHs stay in sediments and particulate matter because they don’t get photochemically oxidized or biologically broken down [ 63 , 64 ].…”

This study focuses on the short-term contamination and associated risks arising from the release of Polycyclic Aromatic Hydrocarbons (PAHs) due to the 2020 Baghjan oil blowout in upper Assam, India. Shortly after the Baghjan oil blowout, samples were collected from water, sediment, and fish species and examined for PAHs contents. The results of the analysis revealed ΣPAHs concentrations ranged between 0.21–691.31 μg L-1 (water); 37.6–395.8 μg Kg-1 (sediment); 104.3–7829.6 μg Kg-1 (fish). The prevalence of 3–4 ring low molecular weight PAHs compounds in water (87.17%), sediment (100%), and fish samples (93.17%) validate the petrogenic source of origin (oil spill). The geographic vicinity of the oil blowout is rich in wildlife; thus, leading to a significant mass mortality of several eco-sensitive species like fish, plants, microbes, reptiles, amphibians, birds and mammals including the Gangetic River dolphin. The initial ecological risk assessment suggested moderate to high-risk values (RQ >1) of majority PAHs concerning fish, daphnia, and algae species. This study highlights the need for recognizing the potential for short-term exposure to local species. To safeguard local ecosystems from potential future environmental disasters, it is imperative for the government to adopt a precautionary strategy.

“…Most of the elasmobranchs in this analysis resulted with moderate RV to fishing activities in Mexico. However, future analysis should consider that species may be subject to other sources of pressure (e.g., overlapping with fishing fleets from other countries, oil spills, climate change, and habitat loss) (Calich et al, 2018;Osgood et al, 2021;Yan et al, 2021;Romo-Curiel et al, 2022). Moreover, half of the evaluated elasmobranchs in this study belong to extinction risk categories of the Red List of Threatened Species of the International Union for Conservation of Nature (IUCN) of Critically Endangered, Endangered, and Vulnerable (Supplementary Table S3).…”

The main key drivers of vulnerability for marine species are anthropogenic stressors, ranging from pollution and fishing to climate change. The widely documented impacts of fishing activities on marine species, the growing concern about the population status of many marine species, and the increase in per capita consumption of marine products worldwide have led to the development of environmentally responsible fishing standards and initiatives to inform consumers about the health status of the species. In Mexico, fishing is a vital source of jobs and food security for many coastal communities, but the population status of many species of commercial importance has not been evaluated. Management efforts and fisheries certification procedures and standards to achieve the sustainability of many Mexican fisheries are hindered by a lack of biological and fishery data for many species. In this study, a risk assessment methodology for data-limited fisheries, a Productivity, and Susceptibility Analysis was used to estimate the relative vulnerability of marine invertebrates and fishes commercially important in Mexico to fishing. Ninety-eight invertebrates, 66 elasmobranchs, and 367 bony fish were analyzed. The vulnerability among the 531 evaluated species is high for 115 (22%), moderate for 113 (21%), and low for 303 (57%). The most vulnerable species are the Mexican geoduck (Panopea globosa) and the Black Sea Cucumber (Holothuria atra) for invertebrates, the Spiny butterfly ray (Gymnura altavela) among elasmobranches, and the Black-and-yellow rockfish (Sebastes chrysomelas) for bony fishes. This study provides a first screening of the many species potentially affected by fisheries, prioritizes marine species for future research and management efforts, identifies the main data gaps, and sets the baseline for future research efforts and management. Furthermore, the results could improve market-based approaches like eco-labeling initiatives and the Responsible Seafood Consumption Guide, developed by Mexican authorities in collaboration with Comunidad and Biodiversidad (COBI, a civil society organization), to inform consumers about the origin and sustainability of fishery products.

“…Species distribution models of large pelagic fishes have been extensively used to predict suitable areas 29 , identify hotspots 1 , 30 , and assess the potential impacts of climate change 31 and of anthropogenic events such as oil spills 30 , 32 or fishing mortality 13 , 19 . We implemented mixed-effects Bayesian spatial models with an integrated nested Laplace approximation (INLA) 33 , which has demonstrated to be a great alternative for modeling species distributions and environmental preferences 1 , 34 , giving results in terms of posterior probability distributions instead of fixed values, and incorporating several types of random effects of both spatial and temporal nature, with reduced computational times 35 , 36 .…”

Yellowfin tuna, Thunnus albacares, represents an important component of commercial and recreational fisheries in the Gulf of Mexico (GoM). We investigated the influence of environmental conditions on the spatiotemporal distribution of yellowfin tuna using fisheries’ catch data spanning 2012–2019 within Mexican waters. We implemented hierarchical Bayesian regression models with spatial and temporal random effects and fixed effects of several environmental covariates to predict habitat suitability (HS) for the species. The best model included spatial and interannual anomalies of the absolute dynamic topography of the ocean surface (ADTSA and ADTIA, respectively), bottom depth, and a seasonal cyclical random effect. High catches occurred mainly towards anticyclonic features at bottom depths > 1000 m. The spatial extent of HS was higher in years with positive ADTIA, which implies more anticyclonic activity. The highest values of HS (> 0.7) generally occurred at positive ADTSA in oceanic waters of the central and northern GoM. However, high HS values (> 0.6) were observed in the southern GoM, in waters with cyclonic activity during summer. Our results highlight the importance of mesoscale features for the spatiotemporal distribution of yellowfin tunas and could help to develop dynamic fisheries management strategies in Mexico and the U.S. for this valuable resource.
