Salmo dentex (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 been 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 (55 °F) 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 is a generic common name for numerous species of carnivorous freshwater ray-finned fishes belonging to the genera Oncorhynchus, Salmo and Salvelinus, all of which are members of the subfamily Salmoninae in the family Salmonidae. The word trout is also used for some similar-shaped but non-salmonid fish, such as the spotted seatrout/speckled trout.
The Neretva, also known as Narenta, is one of the largest rivers of the eastern part of the Adriatic basin. Four hydroelectric power plants with large dams provide flood protection, electricity and water storage. The Neretva is recognized for its natural environment and diverse landscapes.
Salmo is a genus of ray-finned fish from the subfamily Salmoninae of family Salmonidae, and is part of the tribe Salmonini along with the sister genera Salvelinus and Salvethymus. Almost all Salmo species are native only in the Old World, the only exception being the Atlantic salmon, which is also naturally found across the North Atlantic in eastern North America.
Salmo obtusirostris, commonly known as the softmouth trout, also known as the Adriatic trout, or Adriatic salmon, is a species of salmonid fish endemic to a handful rivers spilling into Adriatic in the Western Balkans, in southeastern Europe, namely in Bosnia and Herzegovina, Croatia and Montenegro. The scientific name has changed several times through history; synonyms include Thymallus microlepis, Salmothymus obtusirostris and Salar obtusirostris.
Ohrid trout or the Lake Ohrid brown trout is an endemic species of trout in Lake Ohrid and in its tributaries and outlet, the Black Drin river, in North Macedonia and Albania. Locally, the fish is known as охридска пастрмка in Macedonian and Koran or Korani in Albanian.
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.
The Neretvan nase or Dalmatian nase, Serbo-Croatian: podustva, is a species of freshwater fish in the family Cyprinidae. It is found in Bosnia and Herzegovina and Croatia.
Jablaničko Lake is a large artificially formed lake on the Neretva River, right below Konjic where the Neretva expands into a wide valley. The river provided a lot of fertile, agricultural land there before the lake flooded most of it. The lake was created in 1953 after the construction of Jablanica Dam near Jablanica in central Bosnia and Herzegovina.
Salmo ohridanus, also known by the local name as the belvica in North Macedonia or belushka in Albania, is a species of freshwater salmonid fish, endemic to Lake Ohrid in Albania and North Macedonia.
Salmo aphelios is a species of trout, a salmonid fish endemic to Lake Ohrid in North Macedonia and Albania in the Balkans.
Salmo marmoratus, the marble trout, is a species of freshwater fish in the family Salmonidae. It is characterized by a distinctive marbled color pattern and high growth capacity. The marble trout is found in only a handful of drainages and rivers of the Adriatic basin in Italy, Slovenia, Croatia, Bosnia and Herzegovina, and Montenegro, while in Albania, the species is considered most likely extirpated.
Konjic is a city located in the Herzegovina-Neretva Canton of the Federation of Bosnia and Herzegovina, one of two entities that make up Bosnia and Herzegovina. It is located in northern Herzegovina, around 60 kilometres (37 mi) southwest of Sarajevo, in a mountainous, heavily wooded area, and is 268 m (879 ft) above sea level. The municipality extends on both sides of the Neretva River. According to the 2013 census, the city of Konjic has a population of 10,732 inhabitants, whereas the municipality has 25,148.
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.
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 is an extension and outlet 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. The river has rich biodiversity, with numerous fish species endemic to the Neretva basin inhabiting Krupa and its lakes. It is observed that important Salmo marmoratus, known under its vernacular name as glavatica and/or gonjavac, and endemic to the handful of rivers of the Adriatic watershed, enters these waters to spawn.
The Bunica is a short river in Bosnia and Herzegovina and a left-bank tributary of the Neretva. It is also a main tributary of the Buna. Its source, Vrelo Bunice, is located under sharp cliffs between the villages of Hodbina and Malo Polje, 14 km south from Mostar. It is a very deep and strong karstic spring and difficult to access. Together with the Buna river, it flows west for approximately 10 km and joins the Neretva river near the village of Buna. The Bunica is inhabited by endemic trout species known under its vernacular name as Softmouth trout.
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 (transl. parish).
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 Vrljika is short sinking river in Croatia and Bosnia and Herzegovina, belonging to Neretva River basin. Its source is located on the outskirts of village Proložac near town of Imotski, Croatia. The Vrljika River is home of endangered endemic Softmouth trout, also known as Adriatic trout.
Salmo farioides, commonly known as the West Balkan trout, the Adriatic brown trout, or the Balkan brook trout, is a species of ray-finned fish found in the Balkans, including Albania, Croatia, North Macedonia, among others. It is an important fish in numerous rivers and lakes throughout the region. Identification of Salmo farioides is difficult due to the high degree of endemism in the western Adriatic and Mediterranean area, particularly among salmonid species, and because of high phenotypic diversity among trout populations specifically.
