Luciobarbus microcephalus differs from other types of genera Luciobarbus and Bewnk 45 to 50 scales in the side line series (SL), the last unexpected fins of the dorsal fin is stingy and mostly sawn from its back edge. The dorsal fin is concave in its back. The head length is 22 to 27% of the standard length. The lower lip is narrow, without a central lobbon, the lower jaw tip is not covered by the lower lip. The fish are already fully grown with a body length of 26 to 40 centimeters. [3] The end weight is between eight and nine kilograms. These weights are still exceeded in waters such as the Lagunas de Ruidera, Peñarroya or Tablas de Daimiel. [4] In the Rio Guadiana and Tajo, copies of nine to twelve kilograms of body weight have already been caught. [5] [6]

Microcephalus distribution area (green)

Luciobarbus microcephalus occurs in Portugal and Spain. Her occurrence in lowland flows such as the middle and lower reaches of the Rio Guadiana or in the river system of the Rio Tajo is particularly common. It was partially introduced in Morocco. [3] Their natural habitat is deep and slowly flowing rivers and currents as well as traffic jam areas. [3]

L. microcephalus feeds on plants, detritus and small animals. [7]

Luciobarbus microcephalus serves as a sports fish for anglers in some regions. [3]

Hazard status [ Edit | Edit the source text ]

The type of fish is classified as endangered by the IUCN. [8] In the Bern Convention [9] , Appendix III, will L. microcephalus listed as a species worth protecting. Habitat and individual density of Luciobarbus microcephalus will decrease even further in the future. It is assumed that in 2020 only half of the population will be available that existed at the beginning of the 21st century. The main reasons for the threat are water pollution [ten] , Water deprivation for agricultural irrigation and dam construction, such as the planned dam of Alquedi [11] . Introduced foreign fish species are another problem. [twelfth]
