The blue sucker is a long-lived freshwater species of fish in the sucker family that is of conservation concern.

Coregonus vandesius, the vendace, is a freshwater whitefish found in the United Kingdom. Population surveys since the 1960s have revealed a steady decline and the fish is no longer present in some of its previous haunts but is still present in Bassenthwaite Lake and Derwent Water. The main threats it faces are eutrophication and the introduction of alien species of fish which eat its eggs and fry. The International Union for Conservation of Nature has rated its conservation status as "endangered".
The European bitterling is a temperate freshwater fish belonging to the subfamily Acheilognathinae of the family Cyprinidae. It originates in Europe, ranging from the Rhone River basin in France to the Neva River in Russia. It was originally described as Cyprinus amarus by Marcus Elieser Bloch in 1782, and has been referred to in scientific literature as Rhodeus sericeus amarus. It is known simply as "the bitterling" in its native range, where it is the only species of its genus Rhodeus, and sometimes in the scientific literature, also, but this is technically wrong, being a leftover from the times when the European bitterling was united with its Siberian relative, the Amur bitterling, in R. sericeus. Properly, "bitterling" can refer to any species of Acheilognathus or Rhodeus.
The deepbody bitterling or Itasenpara bitterling is a species of freshwater fish in the family of Cyprinidae. It is endemic to central and southern Japan. It grows to a maximum length of 8.0 cm.
Alburnus belvica. the Prespa bleak, is a species of ray-finned fish in the family Cyprinidae, that can be found in Lake Prespa and the nearby Small Prespa Lake in the Balkans. In North Macedonia it is known as nivichka (нивичка). It is threatened by habitat loss. This species makes up the bulk of the diet of the Dalmatian pelican population breeding at the Small Prespa Lake.
Cyprinus micristius, the Dianchi carp, is a critically endangered species of ray-finned fish in the family Cyprinidae. It is found only in Lake Dianchi and its tributaries in Yunnan, China. The nominate subspecies from the lake itself has not been confirmed since the 1960s.
Yunnanilus nigromaculatus is a species of stone loach endemic to the Dianchi Lake basin in China, but has apparently been extirpated from Dianchi Lake itself due to heavy pollution. It was formerly placed in the genus Eonemachilus.

Mesopristes elongatus is a species of fish in the family Terapontidae known by the common name plain terapon. It is endemic to Madagascar, where it occurs in several rivers along the eastern coast. Its populations are thought to be decreasing due to habitat loss and degradation, which is accelerated by the siltation caused by deforestation.
The Dianchi bullhead, Pseudobagrus medianalis, is a species of catfish in the family Bagridae. It is endemic to the Lake Dianchi basin in Yunnan, China. It can grow to 20 cm (7.9 in) TL. It is a cryptic, benthic fish that hides during the daytime and forages on small fishes and aquatic invertebrates at night.
The redside dace is a species of ray-finned fish in the family Cyprinidae, found in the United States and Canada. It is unique among minnows, being the only species to routinely feed on flying insects by leaping from water. Thus, it acts as a conduit for nutrient transfers between terrestrial and aquatic environments. The species can be used as an ecosystem health indicator, as it is sensitive to environmental disturbances.
Fuxian Lake stretches out through Chengjiang, Jiangchuan and Huaning Counties in Yunnan Province, spanning an area of 212 square kilometers. The lake is ranked third-largest in Yunnan, after Dian Lake and Erhai Lake. Also the deepest lake in Yunnan, it is 155 meters deep at its greatest depth.

The species started to decline in the 1970s and has not been caught in the lake after two specimens were collected in 1985; it may be extinct. Its demise is likely due to introduced fish species, grass carp. It was also impacted by over-fishing and pollution. They grow to a maximum length of 23 cm. They are dark grayish with a silvery white belly, gray dorsal fin, reddish anal fin and orange red caudal fin. They have a rounded belly, blunt snout, eyes on the lateral of their heads, small and transverse mouth.
