UK Marine Ornamental Trade: Species-Level Import Records on Corals, Invertebrates, and Fish in 2018 and 2019 dataset https://portal.medin.org.uk/portal/start.php?tpc=009_CEFASffc19061-a48f-4f72-bb10-df0fefa95283 The dataset provides species-level information, as declared by the exporter, for marine ornamental species that were imported into the UK during select periods in 2018 and 2019. The study was undertaken to support the provision of higher resolution data on the UK’s marine ornamental trade at a Convention on International Trade of Endangered Species of Fauna and Flora (CITES) technical workshop on the conservation and management of marine ornamental fish (Decision 18.296). The dataset provides a snapshot in space and time of the UK's marine ornamental import trade and should be interpreted as such. 20251127 20250717
