Antakelsen om at "Eldstjärten" er utryddet i naturen stammer fra Maurice <b>Kottelat</b>, som er en av verdens fremste eksperter på Sørøst-Asias fiskefauna i sötvatten. Det er altså grunn til å frykte at han har rett i dette.
...
Kottelat & Whitten (1996, side 27) sier følgende om akvariefiskhandelen og statusen for Epalzeorhynchos bicolor:
"<b>Pet trade. </b>The aquarium fish trade has been accused of driving species to extinction because of very selective overfishing, but there is no documented evidence for this. Some species which have been the subject of an important trade have decreased significantly and have disappeared in part of their original range, but this has always been related to other causes (e.g. Botia sidthimunki in Thailand). Some species have disappeared also in areas where they had never been collected for the aquarium trade (e.g. the 'silver shark' Balantiocheilos melanopterus in the Kapuas basin, west Bomeo). <b>On the other hand, some species may be temporarily saved from extinction because of the trade; for example, it is not clear whether the 'red-tailed shark' Epalzeorhynchos bicolor (commonly called Labeo bicolor) still exists in the wild, but tens of thousands of specimens are exported annually from Thailand, all now captive bred.</b>"

Tack, Svein, jag borde ha kollat källan själv, men jag erkänner att jag litade på red list databank.
Jag tycker du bör skicka det där urklippet till IUCN red list (redlist@ssc-uk.org) och till fishbase (R.Froese@cgiar.org); jag misstänker att det kan finnas politiska skäl till varför de anger insamling för akvariehandel som skäl till utrotningen.
Åtminstone fishbase tar säkert åt sig en sån rättning väldigt snabbt.
