Oxynoemacheilus hamwii, the Orontes sportive loach, is a species of ray-finned fish in the genus Oxynoemacheilus. This species is found in the headwaters of the Orontes River but is now restricted to three streams in the Turkish part of the drainage, two joining the lower Orontes in Turket and the third flowing into the Afrin River in Syria, and has been extirpated from Syria. It was described as being very common in the late 20th century, but it is sensitive to pollution and requires clear, flowing streams over mud or gravel. The drainage of the Orontes is heavily used by humans and lower rainfall in the region caused by climate change may exacerbate the threat to this species by increasing the amount of water taken from the streams by humans and by lowering the water table.
Nemacheilus stigmofasciatus, the Thuttinjet stone loach, is a species of ray-finned fish in the genus Nemacheilus which has been recorded from just one locality in the west flowing river Seethanathi at Thuttinjet in Karnataka. This locality is at an altitude of 199m above sea level and has many cascades and waterfalls in its upstream portion. The stream is dominated by the presence of pebbles and boulders with gravel and sand making up approximately 5% of the substrate.

The mountain madtom is a North American species of temperate freshwater fish belonging to the Noturus genus of the family Ictaluridae. The species was first described to the United States National Museum by Professors Jordan and Gilbert in the Big Pigeon River. The mountain madtom has a body that is characterized as being robust, and by the toxic sting that is associated with their pectoral and dorsal spines. Currently, the Pigeon River Recovery Project is working to try to restore the mountain madtom population that was lost in fisheries. Aside from the Pigeon River Recovery Project, there is little management being applied to this species, and it is currently listed on the threatened species list for the state of Tennessee.
