Abstract The sea trout, Salmo trutta L. population in the Vistula River was largest Baltic Sea. Its primary spawning grounds were located Carpathian tributaries upper river basin. fish ascended to spawn two runs: winter when immature and spent nearly a whole year river, summer mature spawned within few months. This work presents fisheries stocking history scientific studies of this from late nineteenth century. consequences most important changes trout habitat are tracked construction basin...
Sea trout (Salmo trutta m. trutta) is a migratory form of brown common in the Baltic Sea. Nine populations from southeast (Poland; Lithuania; Denmark, Bornholm; Estonia and Russia) were genotyped using iPLEX Gold technology (Sequenom) with 62 informative SNPs. A diagnostic panel 23 SNPs was applied to estimate genetic differentiation assess population structure sea trout. The highest level pairwise FST differences observed between Russian (East Gulf Finland) Polish (Baltic main basin)...
Abstract Sea trout, S almo trutta L ., populations in the Slupia River basin have been affected by mass stocking with smolts and fry. This work is focused on a small‐scale differentiation sea trout from one strong emphasis relationship between wild hatchery origin fish. A total of 216 were genotyped at 10 microsatellite loci. Global F ST obtained amova was low 0.0165. Pairwise significant for all tests except stocked adults. The highest pairwise difference found sample Kwacza ( = 0.038)....
Native populations of Atlantic salmon in Poland, from the southern Baltic region, became extinct 1980s. Attempts to restitute Poland have been based on a Latvian population Daugava river. Releases hatchery reared smolts started 1986, but date, only one with confirmed natural reproduction has observed Slupia Our aim was investigate genetic differentiation using 7K SNP (single nucleotide polymorphism) array order assess impact restitution Poland. One hundred and forty samples were collected...
Abstract The European eel, Anguilla anguilla L., is an endangered species. Barriers to its downstream spawning migration are one of the greatest threats this species faces. There hundreds hydroelectric plants (HEP) on rivers in Poland (> 600), and thousands throughout Europe. Eel that pass through HEP turbines as they migrate suffer high mortality, but depends mainly local technical conditions. Silver eel mortality was estimated possibility fish bypassing studied between November 2013...
The genetic relationship between original Atlantic salmon populations that are now extinct in the southern Baltic Sea and present-day has long been controversial. To investigate clarify this issue, we successfully genotyped individuals of historical from Oder Vistula Rivers using DNA extracted dried scales with single nucleotide polymorphism array. Our results showed a global F ST 0.2515 for all pairs loci, which indicates high level differentiation among groups analyzed study. Pairwise...
Abstract The developmental pathways of the offspring three groups trout, Salmo trutta L., with known life histories were compared: one group from a freshwater resident population and two an anadromous (fish that have smoltified fish not). hybridized within group, 27 families obtained reared mixed in tanks. Tracking specimens was possible thanks to individual passive integrated transponder (PIT) tagging. All followed different pathways. Faster growth favored early smoltification maturation at...
Abstract In 1969, a dam was constructed on the Vistula River, longest in Baltic drainage basin, 276 km from its estuary, which resulted collapse of migratory fish populations throughout basin. The existing, ineffective fishway rebuilt 2014. Monitoring at new indicated that 24 species used it, and over period five years number individuals fluctuated nearly 4,000 to 23,000. Radio frequency identification (RFID) technology investigate 12 species, mostly vimba bream, passing through fishway....
La réponse de juvéniles saumon aux fortes baisses niveau caractéristiques l'étiage n'est pas bien connue. Trois expériences ont été menées en fin d'été dans un ruisseau artificiel comportant des séries 3 biefs (10 m x m) constitués d'amont aval séquences d'habitat radier, plat, profond. En eau profonde, les tacons ne réagissent et débit. Dans eaux peu profondes, ils réduisent leur activité, particulier alimentaire, conditions critiques, une partie la population se déplace vers plus proche...
Growth and smoltification were followed during the first year of life in 14 full sibling families sea trout, Salmo trutta m. L., originating from Vistula stock. Until January, reared separately, then together after they had been PIT tagged. The degree was evaluated second spring. Smolts noted each family. percentage these, which ranged to 66%, depended on mean fish length October (r 2 = 0.338) January 0.346). In either or that smolted next spring were, average, longer than those did not, but...
Large areas of the £eba River catchment are inaccessible for fish because barriers, and this reduces significantly their spawning possibilities. The sea trout Salmo trutta L. population in is sustained through compensatory stocking with smolts. In autumn 2007 2008, seventy two were caught a lake, which river flows, several kilometers upstream from its mouth. These individuals tagged radio transmitters that recorded by automatic stations river. They also monitored active telemetry. Only 26...
Abstract Several rivers that are tributaries of the Oder estuary inhabited by Salmo trutta L, most important which Ina, Gowienica, and Wołczenica. Both forms species, sea trout resident brown trout, present. All traditionally stocked with either from neighboring Pomeranian river Rega basin or various locations. To examine populations in these terms genetic structure, diversity, origin, they were analyzed using 13 microsatellite loci. Relatedness was also assessed for fish same year. The...
Selection, genetic drift, and gene flow affect variation within populations differences among populations. Both drift selection tend to decrease increase populations, whereas increases but leads being related. In brown trout (Salmo trutta L.), the most important factor in population fragmentation is disrupted river-segment connectivity. The main goal of study was use analysis estimate level resident migratory potential hybridization areas located downstream impassable barriers one river...
The native population of the salmon, Salmo salar L., in S³upia River probably became extinct 1960s. restoration this species began 1986, and is based on Daugava River. As indicated by historic data, salmon was decidedly less abundant than sea trout, trutta L. This remains unchanged today. To date, it has been impossible to differentiate positively smolts stocking origin from those natural spawning. Since 2006, all released into have had their adipose fins clipped, which allows for easy...
