(Heckel, 1852)

Salmo dentex is a variety of trout, a freshwater fish in the family Salmonidae, found in the western Balkans. [1] [2] [3] Until recently the identity, biological distinctness and species status of the dentex trout were not properly clarified, [4] but genetic data now suggest it is not a monophyletic unit that could be distinguished from other salmonids as a separate species. [5]

Salmo dentex has been reported to inhabit the Neretva river and Hutovo Blato wetlands in Bosnia and Herzegovina, [6] and is also found in Albania and Montenegro in Lake Skadar and its tributaries. [7] It is reported that S. dentex is extinct from Croatian rivers, Cetina and Krka, [8] but has recently bee reported by anglers from the Cetina river in Croatia. Some reports indicate its presence in the rivers of Livanjsko field in Bosnia and Herzegovina [9] and in river Alfeios in Greece. [10]

The status of S. dentex, locally known as the zubatak, long remained unclear due to lack of samples for detailed analyses, hybridisation with other trout lineages and diverse and multiple designations of the same trout in different areas. One of the inhabited areas, the Hutovo Blato wetlands, is situated North West of the Neretva river estuary in southern part of Bosnia and Herzegovina. This is an atypical type of wetland, characterized by several shallow lakes and channels filled with clear and cold water (around 13 °C whole year) creating conditions suitable also for salmonids. [4]

Recently the genetic structure of S. dentex and its relations to other co-existing salmonids in the Neretva and Skadar river systems have been studied using mitochondrial DNA, microsatellite [5] and 21 other nuclear DNA loci. [11] Genetic analyses showed that the Neretva S. dentex ("zubatak") and the co-existing marble trout (S. marmoratus) formed a genetically unified cluster, while Skadar S. dentex ("strun") was "genetically distinct from S. marmoratus in the same river system and indistinct from local brown trout (S. trutta)". Thus the Neretva and Skadar S. dentex are not closely related but rather "S. dentex [is] a particular life history form of S. marmoratus in the Neretva basin and of S. trutta in the Skadar basin". "These results clearly demonstrate that S. dentex does not represent a monophyletic lineage and should not be considered a distinct species." [5]

Trout Number of species of freshwater fish

Trout are species of freshwater fish belonging to the genera Oncorhynchus, Salmo and Salvelinus, all of the subfamily Salmoninae of the family Salmonidae. The word trout is also used as part of the name of some non-salmonid fish such as Cynoscion nebulosus, the spotted seatrout or speckled trout.

Neretva River in Bosnia and Herzegovina and Croatia

The Neretva, also known as Narenta, is one of the largest rivers of the eastern part of the Adriatic basin. Four HE power-plants with large dams provide flood protection, power and water storage. It is recognized for its natural environment and diversity of its landscape.

<i>Salmo</i> Genus of fishes

Salmo is a genus of fish in the salmon family Salmonidae that includes the European species of salmon and trout, among them the familiar Atlantic salmon Salmo salar and the brown trout Salmo trutta. The natural distribution of Salmo also extends to Northern Africa and to Western Asia around the Black Sea basin. The single Salmo species naturally found in the Atlantic North America is the Atlantic salmon, whereas the salmon and trout of the Pacific basin belong to another genus, Oncorhynchus. The generic name Salmo derives from the Latin salmō (salmon). The number of distinct species and subspecies in Salmo is a debated issue. Atlantic salmon and brown trout are widespread species, while most of the other taxa are narrowly distributed forms endemic to single watersheds.

Hutovo Blato

Hutovo Blato is a nature reserve and bird reserve located in Bosnia and Herzegovina. It is primarily composed of marshlands that were created by the underground aquifer system of the Krupa River. It is fed from the limestone massif of Ostrvo that divides the Deransko Lake and Svitavsko Lake. The reserve is on the list of BirdLife International's Important Bird Areas. It is the largest reserve of its kind in the region, in terms of both size and diversity. It is home to over 240 types of migratory birds and dozens that make their permanent home in the sub-Mediterranean wetlands surrounding Deransko Lake. In the migration season, tens of thousands of birds fill the lake and its surroundings.

Rakitnica River in Bosnia and Herzegovina

Rakitnica is the main tributary of the first section of the Neretva river, also called Upper Neretva (Bosnian: Gornja Neretva). It meets Neretva from the right, flowing from north to south, between Bjelašnica and Visočica mountains.

Desilo

Desilo is an underwater archaeological site in southern Bosnia and Herzegovina, located near the Neretva river and the Croatian border. The site was first discovered in the late 20th century, but Desilo's history can be traced as far back as ancient times. Investigations by a University of Mostar archaeological team in 2007 uncovered many sunken boats at the bottom of the small lake in Desilo valley. The archaeologists believe these boats to be Illyrian ships, dating back to the first and second centuries B.C. Further excavations in 2008 by University of Oslo archaeologists found evidence suggesting that Desilo was an Illyrian trading post. These archaeological findings are significant because they are the first known discovery of Illyrian ships. Additionally, Desilo functioning as a trading centre suggests there were peaceful interactions between the Illyrians and the Romans.

Krupa (Neretva)

The Krupa river is a left tributary of the river Neretva and the main water current of Hutovo Blato, which leads the waters from Gornje Blato and Svitavsko Lake into the Neretva river near Dračevo. The length of Krupa is 9 km with an average depth of 5 meters. The Krupa does not have an actual source, but is actually an extension of Deransko Lake. Also, the Krupa is a unique river in Europe, because the river flows both ways. It flows normally from the source to the mouth and from the mouth to the source. This happens when, due to high water levels and large quantities of water, the Neretva pushes the Krupa river in the opposite direction.

Glavatičevo Village in Federation of Bosnia and Herzegovina, Bosnia and Herzegovina

Glavatičevo is a small village in Konjic Municipality, Bosnia and Herzegovina, which is a central village to a group of villages of a wider Glavatičevo, positioned 30 km southeast of Konjic, within a wide Župa Valley straddling the Neretva river. The village and its wider areal, with surrounding villages and the valley, is also referred to as Župa Glavatičevo, or Komska Župa, or simply Župa.

Upper Neretva, is the upper course of the Neretva river, including vast mountainous area surrounding the Neretva, with numerous human settlements, peaks and forests, numerous streams and well-springs, three major glacial lakes near the river and even more scattered across the mountains of Treskavica and Zelengora, in a wider area of the Upper Neretva with its flora and fauna.

The fish fauna of the Neretva river basin in the western Balkans is representative of the Dinaric karst region and characterized by several endemic and endangered species.

The Abant trout is a salmonid fish native to Lake Abant in northern Anatolia. It was initially described as a subspecies of the brown trout Salmo trutta abanticus Tortonese, 1954, but later even considered a full species Salmo abanticus. On the basis of crossing experiments and mtDNA sequences, Kalayci et al. (2018) however proposed that it should be considered a local strain within Salmo trutta, with no distinct species status.
