“…One of the most important pathways for introduction of non-native species is the international pet trade (Early et al, 2016;Novák et al, 2020;Patoka et al, 2020a,b). Freshwater animals exploited for ornamental purposes sometimes escape or are both intentionally or accidentally released from aquaria or garden ponds (Padilla and Williams, 2004;Kalous et al, 2015;Patoka et al, 2017;Magalhães et al, 2017b;Schofield et al, 2019).…”

Ornamental aquaculture is known to be one of the main sources of non-native species and Indonesia has been identified as one of the leading suppliers of these organisms worldwide. Released or escaped ornamental aquatic animals can establish new populations and become invasive. On the other hand, some invasive species can be also endangered in their native range, which is called the “Biodiversity Conservation Paradox”. This is true for Arapaima gigas, one of the popular ornamental creatures and the largest bony fish of all, which is threatened in its native range in parts of Amazonia and which has been found to occur in various localities in Java and Sumatra in Indonesia. Based on climate matching we found the vast majority of Indonesian territory to be suitable for this species establishment. Keeping in mind the size and predatory behaviour of A. gigas, we discussed possible consequences of its spread and impacts on native biota in Indonesia.

“…Keeping wild (i.e., non-domesticated) animals as exotic pets has become increasingly popular across the world in recent decades [ 1 , 2 , 3 , 4 , 5 ] and is a major driver of the global wildlife trade [ 1 , 6 ]. In the UK, the exotic pet market is particularly prevalent [ 7 , 8 , 9 ].…”

Keeping exotic pets has become a popular habit in the UK in recent decades. Yet, information on the current scale of the trade and the diversity of animals involved is lacking. Here, we review the licensed sale of amphibians, reptiles, birds, and mammals as exotic pets in the UK, identifying current geographical hotspots of trader activity, data gaps, and compliance issues related to this trade. In terms of trade volume, records showed large numbers of individual wild animals, across a wide range of species groups, are being legally sold in the UK. Maximum numbers of exotic pets permitted for sale included 54,634 amphibians, 64,810 reptiles, 23,507 birds, and 6479 mammals. Moreover, nearly 2000 pet traders located in 283 different local authority areas had permission to sell exotic pets. The scope and scale of the trade draws additional attention to the substantial animal welfare challenges associated with it, and our review serves to highlight several shortcomings associated with the licensed exotic pet trade in the UK. Pet shop licences often lacked detailed information about the specific type and number of animals permitted for sale, which raises compliance concerns and hinders efforts to carry out adequate inspection and monitoring. Ninety-five pet traders in England had been given a one star rating, indicating ‘minor failings’ in animal welfare, and some local authorities in England were still operating under the old Pet Animals Act (1951). We recommend that resources should be prioritised and focused towards local authorities in England that are not operating under the new Animal Welfare (Licensing of Activities Involving Animals) (England) Regulations (2018), and that local authorities should improve data reporting on all licenses issued to aid inspection and monitoring.

First report of freshwater atyid shrimp, Caridina formosae (Decapoda: Caridea) as a host of ectosymbiotic branchiobdellidan, Holtodrilus truncatus (Annelida, Citellata)

In recent years, ornamental shrimps gained increasing popularity in the aquarium trade. Unfortunately, they are potential vectors of epibionts, which may be unintentionally introduced to aquaria with imported shrimps. This contribution presents the first report of the occurrence of Holtodrilus truncatus on aquarium freshwater shrimp Caridina formosae. A total of 120 shrimp imported from Taiwan as aquarium pets were examined for the presence of epibionts. Holtodrilus truncatus occurred in 23.3% of shrimps. A total of 29.6% of crustaceans showed signs of damages as a result of H. truncatus activity. The shrimp is not common in the ornamental trade and is not subject to selective breeding. Therefore C. formosae populations available on the market, if not wild-caught, are most likely very similar to those occurring in Taiwanese natural water bodies, where H. truncatus occurs in Neocaridina shrimp. Neocaridina spp. are a known host for this epibiont, and transmission between species might occur in nature as well as in the aquarium trade were densities of animals are often high. The ability of H. truncatus to infect also highly invasive crayfish Procambarus clarkii, might also pose concern for regions where this crustacean is widespread. The actual lack of preventive measures for shrimp epibionts as well as confirmed releases of ornamental crustaceans into new aquatic ecosystems may result in further spread of H. truncatus, a potential new threat to native crustaceans and other epibionts.
