Fish of Timor
The Fish List of Timor lists the fish species that live in the freshwater and brackish water near the coast of the Southeast Asian island of Timor . In the waters of the state of East Timor , according to Larson et al. 56 species known so far (as of 2007). Since different sources give different information about the known species, there are more species in the list. Other species were discovered in earlier studies, but not specifically assigned to the Indonesian West or East Timor (see literature ).
Overview
Endemic freshwater fish in the rivers of Timor are the only four centimeters long Oryzias timorensis from the family of rice fish (Adrianichthyidae) and Craterocephalus laisapi from the genus hard-headed . Quite a few species of East Timor are better known from the brackish water of the estuaries and mangroves , including the families of the cross catfish (Ariidae), the gobies (Gobiidae) and the archer fish (Toxotidae). The carp , the African catfish ( Clarias gariepinus ) and the Cyprinodontiformes Guppy , mosquitofish and Panchax ( Aplocheilus panchax ) were introduced by man.
The water system of the Ira Lalaros , the largest lake on the island, and the populations of aquatic inhabitants living in it are practically cut off from the outside world. The outflow of the lake, the Irasiquero, disappears in a ponor . Color tests have shown that the water reappears in three springs south of the Paitchau mountains and in four springs near Com on the north coast. A total of 21 different fish species live in the lake, two native and four imported fish species in Irasiquero.
Most of the rivers on the north coast of Timor are dry outside the rainy season . Only those whose headwaters are in the south, such as the northern Lacló , the Seiçal and the Lóis , flow all year round. The water of some springs in the north, such as those of Ira Ono , Lutu Ira and Came Ira , do not reach the sea because their water is used to irrigate fields or as drinking water.

| Liza melinoptera | For the first time in East Timor, the species belonging to the mullet was detected in the Aramaco in 2006. The fish migrate into rivers from the sea. In the Aramaco they were found in isolated basins, on the tidal line , two kilometers upriver from the coast. | |

| Common argus fish | Scatophagus argus | |
| Sicyopterus caeruleus | Detected for the first time in 2006 in East Timor in the rivers Aramaco, Veroruhu and Vero (Nair-Ete source). It is possible that the species was incorrectly identified as Sicyopterus cynocephalus by Weber and de Beaufort in 1912 . The naming of the species is currently still controversial. | |

| Stenogobius blokzeyli | Detected for the first time in 2006 in East Timor. Only one male of the species was found in Irebere. The species was previously only known from two female specimens from Bali that were in poor condition. The male is small and has more teeth than the two females. S. zurstrasseni is a possible synonym of Art. | |
| Stiphodon semoni | First detected in 2006 in East Timor 2007 in the Tchino, its spring and the Han spring , west of the Vero. In 2004 a specimen was found that was then described as a small representative of Stiphodon cf. atratus . In view of the adult animals found in 2006, it is possible to assign all of them to S. semoni . There are currently taxonomic studies that also suggest a new species that is related to S. atratus and resembles S. semoni . | |
| Three-lined tiger bass | Terapon jarbua | |
| Archer fish | Toxotes jaculatrix | |
