Ameca River

Several species of fish are only found in the Ameca River basin: the butterfly splitfin, Tequila splitfin, finescale splitfin, banded allotoca, golden skiffia, Amatlan chub, Ameca chub and Ameca shiner. All these are highly threatened. The Tequila splitfin, finescale splitfin and golden skiffia are likely already extinct in the wild; but all three survive in captivity. The butterfly splitfin and banded allotoca were also thought to be extinct in the wild, but have since been rediscovered. The Ameca shiner was once feared entirely extinct, but it too survives in captivity. A reintroduction project for the shiner and Tequila splitfin was initiated in 2015. ==References==
