Seahorses are unique, charismatic, and threatened fish that inhabit some of the most vulnerable marine environments. In Brazil, three seahorse species recognized as with extinction; however, knowledge their ecology conservation is unsystematized patchy. Using PRISMA protocol, we performed a systematic review existing literature on Brazilian seahorses to assess current distribution, life history aspects, threats, efforts, while also identifying research gaps proposing future priorities. By accessing 289 studies, found significant population ecology, habitat preferences, particularly for Hippocampus patagonicus H. aff. erectus, including critical taxonomic uncertainties latter. Despite being studied in country, reidi lacks updated large-scale studies. We evidenced major threats Brazil: fisheries (both targeted incidental), trade, destruction. Furthermore, highlight emerging anthropogenic disturbances, such tourism-related activities, potential stressors populations. Weaknesses framework, regarding regulation monitoring these require attention. Our findings provide important insights direct management actions Brazil. emphasize need comprehensive studies address uncertainties, clarify distribution patterns, understand waters.

Ornamental fish are amongst the most popular pets in world, with a massive number of thriving hobbyist groups both online and person. The global trade ornamental is growing rapidly. However, documentation production limited, despite this, considerable inroads have been made to document marine freshwater trade; this information has primarily focused on data collection via import/ export and, as result there still limited captive within nation. While it known that hobbyists produce fish, date little scale production. This study aimed what extent involved fish. used snowball method survey collect current status practices hobby. was hosted two forums, well Facebook™ fishkeeping groups. A total 3304 valid responses were collected, from 76 countries. identified 66.3% surveyed had actively engaged breeding at some point during their hobby another 23.5% indicating they experienced aquarium accidentally. There clear increases active effort experience hobbyists, however not case keepers. majority did seek make profit endeavour, those who saw small annual profits, or exchanged for store credit. Overall, significant pursue stage lays groundwork further engagement community required foster collaboration between them academia.

Abstract The surge in internet accessibility has transformed wildlife trade by facilitating the acquisition of through online platforms. This scenario presents unique ethical challenges for researchers, as traditional frameworks in‐person research cannot be readily applied to realm. Currently, there is a lack clearly defined guidelines appropriate procedures when conducting (OWT) research. In response this, we consulted scientific literature on considerations and examined existing established professional societies boards. Based these documents, present set recommendations that can inform development ethically responsible OWT Key designing executing include violation privacy rights, defining subjects illegality, risk misinterpretation or posing risks participants sharing data. Potential solutions considering participants’ expectations privacy, are authors versus subjects, understanding legal cultural context, minimizing data collection, ensuring anonymization, removing metadata. Best practices also involve being culturally sensitive analyzing reporting findings. Adhering help mitigate potential pitfalls provides valuable insights editors, review boards, enabling them conduct scientifically rigorous advance this growing field.

The pet trade of native species outside of their natural distributions within Australia is a biosecurity risk

Conservation Science and Practice, Год журнала: 2025, Номер unknown

Опубликована: Янв. 6, 2025

Abstract The trade of alien species as pets is increasingly recognized a biosecurity risk due to their intentional and accidental release into the wild. However, are often categorized native or non‐native at national level, meaning that presence outside range, yet within country, may be an overlooked threat. So‐called “domestic non‐natives” have established new populations across several countries and, in some cases, become invasive. Here, we investigated extent domestic Australian pet natural distributions determined whether such locations were climatically suitable for potential establishments. Australia provides unique system explore this issue because it deters most permits keeping large diversity pets. We monitored from popular e‐commerce site used birds, reptiles, amphibians (29 k advertisements over 1 year; July 2019 2020). Of 177 vertebrate observed trade, 129 (73%) had least instances occurring distribution. found environments present range 90 these regions proximal suburbs where trade. Our results indicate non‐native” widespread that, if captive escape released wild sufficient numbers, there establishment species. suggest regulations pertaining ensure careful consideration given circumstances when occurs beyond species' both context other with industries.

Abstract Hypancistrus was proposed as a monotypic genus for highly unique species, H. zebra, known only from short stretch of the Middle rio Xingu on Brazilian Shield. Subsequent studies added eight all described river systems draining Guiana Analysis specimens middle and lower detected two new species that can be separated its congeners based color pattern body size adults, are well ornamental fish trade. Due to their non-overlapping distributions, prospects conserving quite different. One is relatively safe due large distribution throughout Lower channel up downstream end Volta Grande do Xingu, while other in need urgent protection because it restricted at depths greater than 15 meters, lies entirely within impact zone Belo Monte Hydroelectric Power Plant Complex.

Marine or freshwater: the role of ornamental fish keeper’s preferences in the conservation of aquatic organisms in Brazil

PeerJ, Год журнала: 2022, Номер 10, С. e14387 - e14387

Опубликована: Ноя. 11, 2022

Background The use of ornamental fish as pets has important implications for the conservation species used in keeping, particularly relation to overexploitation. Understanding keepers’ relationship with hobby can provide information assessing potential impacts activity. Here, we analyzed profile Brazilian keepers and evaluated their preferences choices. Methods Information was obtained by applying questionnaires 906 participating keeping groups a social network. questionnaire contained questions about kept (freshwater marine), techniques used, socio-economic aspects, associated perspectives. Results Most were young men (20–40 years old), higher education monthly income above US$ 530.00. Participants predominantly freshwater (86%), but marine only (5%) or both hobbyists (9%) also recorded. A total 523 kept, most which comprised (76% total) exotic (73%). About third recorded under national trade restrictions. In addition, declared that they had invertebrates. Marine aquariums require greater financial investment, especially at beginning, than are almost entirely based on species. aesthetic factor is main motivation practicing this hobby, being color behavior key factors choosing fish. 10% have already released into wild, highlighting concerns biological invasions. There an urgent need enforce regulations towards restricting access threatened native potentially invasive species, well measures aimed informing raising hobbyists’ awareness related hobby.

Abstract Online research methods are increasingly used in conservation science to monitor and collect data on online wildlife trade. Shark‐like rays (Rhinopristiformes) among the most threatened vertebrates, prized for their high‐value fins while other uses derivatives largely unrecognized literature. The bowmouth guitarfish ( Rhina ancylostomus ) is characterized by ridges of enlarged thorns, sometimes sold as amulets. Listed Convention International Trade Endangered Species Wild Fauna Flora (CITES) Appendix II, thorn‐market has been ignored undocumented. Using systematic, retrospective searches, we recorded 977 bowmouth‐derivatives sale. In our global multi‐lingual scope, 97% products were offered from Thailand, despite prohibited 98% all thorns (USD3‐300) alongside high‐profile CITES‐listed taxa (e.g., tiger claws). Consistent advertisements 2012 revealed a previously unquantified trade an often‐neglected marketplace elasmobranch research. Our findings offer insight into drivers thorn trade, potentially rooted cultural beliefs. accessible can be applied internationally across species, providing quantitative qualitative insights aspects critically endangered fish. Continued monitoring markets, like this study, necessary fill critical gaps informed policy species‐specific management.
