“…Previous studies carried out in NAV have described how trace metal concentrations in its sediments have become bioavailable to marine species (Páez-Osuna and Osuna-Martínez, 2015), including those of commercial interest (Páez-Osuna and Osuna-Martínez, 2015;Góngora-Gómez et al, 2018;Delgado-Alvarez et al, 2019). In the NAV, one of the most important artisanal fisheries is the blue swimming warrior crab (Callinectes bellicosus) which is exported to international markets at up to 13,000 tons year −1 (Ortega- Lizárraga et al, 2020).…”

This study was carried out in the Navachiste coastal lagoon, Mexico, surrounded by intensive agricultural and aquaculture activities that cause environmental pollution by the deposition of trace metal residues in the sediments of this coastal lagoon. The trace metals are bioaccumulated by benthic organisms such as the blue swimming warrior crab, Callinectes bellicosus, which inhabits this lagoon and is consumed by humans. Ninety-five C. bellicosus edible tissue samples were collected (April 2014–January 2015). The extraction procedure of the trace metals in edible tissue samples was carried out by acid digestion with nitric acid. Based on the Environmental Protection Agency (EPA) of the United States, two indices were used to measure health risk: the estimated daily intake (EDI) and the target hazard quotient (THQ). The hazard index (HI) was used to calculate the probability of adverse carcinogenic risk and the target hazard quotient per sample (MHI) to calculate the probability of developing a carcinogenic or non-carcinogenic risk. The analysis of variance (ANOVA) showed significant differences among trace metal concentrations (p < 0.01), but all trace metal concentrations in the edible tissues of C. bellicosus were higher than the maximum residual limits (MRLs). The highest EDI was for Zn, Fe, and Cu, showing that the consumption of these crabs might represent health risks. The THQ >1 was for Ni, Zn, Cd, and Cu, and the HI = 16 revealed the risk of C. bellicosus for high-level consumers. The MHI showed that 98% of samples presented a THQ >1, implying a high rate of bioaccumulation of trace metals by the crabs independent of the sampling site in the NAV. The presence of trace metals in the edible tissue of crabs reflects contamination by trace metals, and the indices results mean that the NAV lagoon is constantly polluted with trace metal residues by neighboring agriculture and aquaculture activities. These trace metal residues are being bioaccumulated in the edible tissues of C. bellicosus due to its feeding habits, resulting in a health risk if its consumption is high, including carcinogenic and non-carcinogenic risks.

“…Although adult seahorses are recognized as having few predators due to their low nutritional value (Lourie, Pollom and Foster 2016), crabs and large pelagic fish are considered predators (Kleiber et al 2011; Ternes, Gerhardinger and Schiavetti 2016). Direct observations of seahorses with shorter tails also suggest constant partial predation by crabs (Rosa et al 2005), especially in Topolobampo and southeastern Gulf of California, where it is an important fishery resource (Ortega-Lizárraga et al 2020). Therefore, predation studies on seahorses by crabs might be of interest in future research.…”

The Pacific seahorse ( Hippocampus ingens) is an important cultural and economic resource for coastal communities in the state of Sinaloa, Mexico. However, the conservation of this species is threatened by overfishing, habitat loss, and lack of awareness about its ecological importance. In this study, we examine the local ecological knowledge and use of the Pacific seahorse by residents of Sinaloa. Through ethnographic interviews and participant observation, we document the traditional knowledge and practices associated with this species, including its habitat, behavior, and uses. We find that local ecological knowledge has played a crucial role in the management and conservation of the Pacific seahorse, and that community-based approaches are necessary to address the conservation challenges facing this species. Our study provides important insights into the role of traditional ecological knowledge in marine conservation and highlights the need for more collaborative and participatory approaches to marine management and conservation in Sinaloa and other coastal regions.
