The Orontes Bream, aka. Long-spine Bream, described in 1843; it was restricted to Lake Amik in Turkey as well as some water bodies in the Ghab Plain in Syria, which both obtain their water from the Orontes River.
Lake Amik was drained in the 1940 to obtain land for growing cotton but also to eliminate malaria; and the swampy areas in the Ghab Plan were drained in the 1950s, more or less for the same reasons.
The Orontes Bream is now most likely completely extinct.

This Plateau Chub was described in 1894, it inhabited freshwater channels in the Chalco – and the Xochimilco-Tláhuac area in the Valley of Mexico, a region that is no longer existent due to the unstoppable growth of Mexico City.
The species apparently disappeared at around 1954.
The Luhondo Yellowfish was described in 1937; it was endemic to Lake Luhondo in Rwanda and is only known from the type specimen.
The species started to disappear in the late 1930s after the introduction of cichlid species, including tilapias, into the lake, which outcompeted the native fish species.

The Baolan Barbel, locally known as Baolan, was endemic to Lake Lanao on the island of Mindanao, Philippines, where it was said to inhabit deeper waters.
The species reached a length of about 11 cm.
The fish is known from only nine specimens, despite being one of the most highly esteemed for food and apparently the rarest and most difficult to obtain. It is said to have only been caught during the colder months, and only after a storm with the waves still running high.
The species was reportedly last caught in 1963 to 1964, it is now feared to be extinct.
This species, which locally is known as Dipura or Pait, was endemic to Lake Lanao on the island of Mindanao, Philippines.
The species reached a length of about 11 cm.
The species was reportedly last caught in 1982, all subsequent surveys failed to record it and it is now feared to be extinct.
The causes for the extinction of so many endemic fish species from Lake Lanao are the excessive exploitation of fish, which is the main diet for the increasing human population in the area; the traditional fishing methods having been replaced by dynamite fishing, which simply destroys and kills everything, and by the use of several poisons.
This species was described in 1924; it was endemic to Lake Lanao on the island of Mindanao, Philippines.
In the 1960s, the Tank Goby (Glossogobius giuris (F. Hamilton)), a predatory fish species was accidently introduced to the lake, leading to the extinction of several endemic fish species. However, overfishing, rampant use of destructive fishing methods (dynamite fishing), and unsustainable fishing practices certainly played their part too.
The Bitungu was last recorded in 1975 and is now extinct.
The Mexican Chub is one of three known species in this genus, all of them are now extinct due to habitat loss.
This Mexican Chub was described in 1955, it inhabited canals and streams in the Valley of Mexico, a plateau in central Mexico that now is nearly completely overbuilt by Mexico City, one of the largest cities on the planet.
The species died out at around 1983 as a result of the complete drying of the water bodies in the valley due to the withdrawal of water by the agriculture and the unstoppable growth of the city and its suburbs.
The Las Vegas Dace was described in 1984, it was declared extinct in 1986, only two years later.
The Las Vegas Valley in Nevada, USA originally was formed by a river, this river, however, started to disappear at 4000 to 1000 BCE., leaving behind only three springs and becoming merely a dry wash.
The last Las Vegas Daces were cought in 1940 (but were not recognized as being distinct), they apparently survived in one of the springs and outflows until 1955 to 1957, but disappeared sometimes before 1967.
The creek that formerly held the three springs is now obviously completely dry.
