“…Despite its 'Least Concern' status in the IUCN Red List [49], populations of S. biaculeatus are undoubtedly under considerable pressure. The species has been used in TCM for more than 600 years [12] and is considered to be the most heavily exploited pipefish species, although comprehensive range-wide figures are lacking [12,14]. The annual trade of dried pipefish species into Taiwan was reported to be around 1 600-16 500 kg between 1983 and 1993 [12,14], and the annual import of a mixture of pipefish into Hong Kong during 1998-2002 was estimated to have been around 7 500-21 300 kg, with further trade suspected to be occurring in India, Malaysia, Thailand and the Philippines [2,12,14].…”

“…Seahorses and pipefishes belong to this family, along with pipehorses and seadragons [1][2][3][4][5]. Many syngnathids live in highly vulnerable inshore marine habitats [6] such as shallow reefs and lagoons [7,8], mangroves [9], estuaries [7,10,11], seagrass beds and algal flats [12,13]. This makes them highly susceptible to overfishing and habitat destruction.…”

“…In many regions, syngnathids are threatened by commercial overexploitation. Some are sold as curious or aquarium fish [2,5,8,9,14,18], but the Traditional Chinese Medicine (TCM) market is the main consumer of wild syngnathids [12,14,18]. For example, the global annual seahorse trade exceeds 20 million individuals [19][20][21][22].…”

Seahorses and pipefishes are heavily exploited for use in Traditional Chinese Medicine (TCM), and less frequently for curio markets or as aquarium fish. A number of recent studies have used DNA barcoding to identify species sold at TCM markets in East Asia, but the usefulness of this approach in determining the region of origin remains poorly explored. Here, we generated DNA barcodes of dried seahorses and pipefishes destined for TCM that were confiscated at South Africa’s largest airport because they lacked the export permits required for the CITES-listed seahorses. These were compared with published sequences and new sequences generated for Mozambican seahorses, with the aim of determining whether it is possible to identify their country of origin. All pipefishes were identified as Syngnathoides biaculeatus, a widespread Indo-Pacific species, but the published sequence data did not provide sufficient resolution to identify the region of origin. The same was true of the majority of seahorses, which could not even be identified to species level because they clustered among an unresolved species complex whose sequences were published under the names Hippocampus kuda, H. fuscus and H. capensis. The presence of a few specimens of a second seahorse, H. camelopardalis, suggests that the shipment originated from East Africa because the range of this seahorse is centred around this region, but again, it was not possible to determine their country of origin. Even though seahorses and pipefishes have high levels of genetic population structure because of their low dispersal potential, DNA barcoding was only suitable to tentatively identify species, but not their region of origin. DNA barcoding is increasingly used to identify illegally traded wildlife, but our results show that more sophisticated methods are needed to monitor and police the trade in seahorses and pipefishes.

The aim of this study was to analyse the cytotoxicity of heavy metals (HMs) and nanoparticles (NPs) on populations of the ciliated protist Euplotes aediculatus. We used ecotoxicological tests, antioxidant assays, and the MixTOX tool in Microsoft® Excel to evaluate the toxic effect of HMs and NPs in single and binary mixtures on E. aediculatus and to detect the type of interaction between them. Based on our results, the order of toxicity was Cu > Cd >> Zn (1 h and 24 h) for HMs and ZnO > CuO >> TiO2 >> SiO2 (1 h) and CuO > ZnO >> TiO2 >> SiO2 (24 h) for NPs. The interaction between metals in binary mixtures was predominantly synergistic at low doses and antagonistic at high doses. The type of interaction depende on the metals present and their respective concentrations. Furthermore, both HMs and NPs were shown to trigger effective antioxidant responses in E. aediculatus. Our research highlights the importance of considering the combined effects of HMs and NP exposure and their potency in risk assessment.
