The Black Sea Trout, Salmo labrax Pallas, 1814 (Pisces: Salmonidae) in Romanian Waters

Abstract

The review assembles chronological data on Black Sea trout (Salmo labrax) from Romanian waters and brings up-to-date information related to the distribution of the species. The information used dates from 1909 to 2020 and includes books, articles, digital databases, field observations, and notes from different research fields such as ichthyology, biogeography, genetics, aquaculture, conservation, and ecology. Global distribution, migration, meristic characters, and aquaculture of the species were analyzed based on the recorded data from the specialty literature. New information related to a possible population of Salmo labrax inside the Carpathian Arch was discussed. In Romanian waters the species is found in the Black Sea, Danube, Danube Delta but the current paper proposes a new hypothesis, namely that resident populations can be found in rivers and lakes adjacent to the Carpathian Arch. The highest migration point of the Black Sea trout in the Danube was recorded near Corabia locality, Olt County, (43°46′25″N- 24°30′12″E). In the Danube Delta, it was caught in all the three branches (Sulina, Sf. Gheorghe and Chilia), and lagoonary complexes such as Razim-Sinoe. Sexually matured females were caught especially in Spring Season while unmatured specimens were caught in all seasons. Even if the species is protected under Romanian legislation, fishermen and anglers should report its presence when caught accidentally.

“…Fish from the Salmonidae family have great importance economically as a food source, environmental in terms of species diversity and aquatic ecosystem health, as well as socially as they are preferred in angling (Latiu et al 2020). Black Sea salmon (Salmo labrax) is one of the less studied salmonid species compared to other species (Figure 1).…”

Changing climate may mitigate the invasiveness risk of non-native salmonids in the Danube and Adriatic basins of the Balkan Peninsula (south-eastern Europe)

“…This taxon is often considered a complex of distinct species concordant with their matching two distinct haplogroups (Bernatchez 2001), whereas the number of species contained within the Salmo trutta complex remains debatable (Kalayci et al 2018;Makhrov and Lajus 2018). However, the introduction of stream-dwelling Salmo trutta (sensu stricto) of Atlantic origin and of Macedonian trout Salmo macedonicus of Adriatic mitochondrial haplotype, originating from the Aegean Basin, has made this unresolved taxonomy even more complicated (Latiu et al 2020), primarily due to long-term hybridisation (Škraba Jurlina et al 2020). Additionally, several repeated translocations of salmonids have taken place, mainly from the Danube Basin into the Adriatic Basin of the Balkan Peninsula involving European grayling Thymallus thymallus and Salmo trutta of Danube origin.…”

Fish Species Diversity From Someșul Cald River: 50Years After Cascade Dam Constructions

“…Along with the benefits of dams, there are also disadvantages, especially when their effects are projected on wildlife management. The concept of clean/green energy in the case of dams is questioned by some scientists (Li et al, 2019;Laţiu et al, 2020a). Freshwater fish fauna diversity is placed under great stress by anthropogenic activities, causing important ecological alterations (Jellyman and Harding, 2012).…”
