Abstract Elasmobranches are popular animals in public aquariums. Worldwide more than 700 million people visit zoos and aquariums annually, enabling elasmobranches to become an important ambassador for their natural habitats. We conducted a census within the European Association of Zoos and Aquaria to gain a better overview of which species are present within European collections. The census showed that 102 chondrichthyan species are found in European zoos and public aquaria, accounting for 8,6% of all known species. Of the captive population 47.1% of species have reproduced in aquariums. Benthic species are found most commonly in aquariums. Of the species reproducing, 87.8% fall in the body size range of 51 to 250 cm. Categorising the reproductive results by reproductive mode, the most successful groups are oviparous and aplacental viviparous with uterine villi or trophonemata. A regional collection plan has been defined by using the results of the census and the IUCN status. Currently 42 species are managed by a species coordinator, within the ex-situ European elasmobranch population to ensure a genetically healthy population, to increase reproductive output, and to conduct husbandry research. Long-term breeding efforts will help to reduce the demand on wild populations to supply the aquarium population. Species coordinators will become the contact for in-situ conservation initiatives and international conservation bodies like IUCN. This study discusses further the future challenges in the captive management of chondrichthyan populations.
