New research from the University of Exeter and King's College London has shown how a population of brown trout can survive in the contaminated waters of the River Hayle in Cornwall where metal concentrations are so high they would be lethal to fish from unpolluted sites. The team believe this is due to changes in the expression of their genes. The research was funded by NERC and the Salmon and Trout Association. The researchers compared the trout living in the River Hayle with a population...

Be careful what you eat, says University of Notre Dame stream ecologist Gary Lamberti. If you're catching and eating fish from a Lake Michigan tributary with a strong salmon run, the stream fish – brook trout, brown trout, panfish – may be contaminated by pollutants carried in by the salmon. Research by Lamberti, professor and chair of biology, and his laboratory has revealed that salmon, as they travel upstream to spawn and die, carry industrial pollutants into Great Lakes...

In Less Than 100 Years Trout Will Become Extinct In The Iberian Peninsula
2012-09-05 16:24:36

Climate change, pollution, the extraction of water for irrigation and overfishing all threaten the survival of the common trout. This fish is very sensitive to changes in its environment and, according to the Spanish study, its habitat will have reduced by half by the year 2040 and will have completely disappeared from Iberian rivers by 2100, so its population will become extinct. Global warming is threatening the existence of many fish species, especially those in the salmonid family,...

Personality is not just a feature unique to humans and pets. Scientists at the University of Gothenburg (Sweden) have revealed that also brown trout have individual characters and show different personalities. Researcher Bart Adriaenssens from the Department of Zoology at the University of Gothenburg has for many years studied the behavior of juvenile trout from watercourses on the west coast of Sweden. "My results show that it are not just humans and other mammals that exhibit personality....

Trout and salmon are among the world's most familiar freshwater fishes, but numbers have fallen over recent decades "“ in some areas, dramatically. Pollution, habitat loss and over-fishing have all been blamed in the past, but new evidence from Cardiff University shows that climate change could be a major factor, putting both species at risk. The scientists studied populations of young salmon and trout in the River Wye in Wales, traditionally one of the UK's best angling rivers....

Over a 23-year study, Javier Lob³n-Cerviá has found the mechanism that controls the number of salmonids found each year in Cantabrian rivers. His method has been to monitor population numbers in relation to river flow in March, when the juvenile fish emerge. He concludes that environmental conditions change each year and modify river flow, positively or negatively affecting survival rates. This information throws light on a long debate within ecological theory about the mechanisms...

Atlantic salmon have returned to France's Seine River with gusto, after disappearing for the past hundred years. This year has seen hundreds of these salmon swimming past the Eiffel Tower and Notre Dame cathedral, researchers told AFP. It is remarkable that salmon and other species, which had previously been chased away by dams and pollution, are now popping up again without any human effort to bring them back. "There are more and more fish swimming up the Seine," said Bernard Breton, a top...

The impact fish stocking has on aquatic insects in mountain lakes can be rapidly reversed by removing non-native trout, according to a study completed by U.S. Forest Service and University of California, Davis, scientists. Their findings appear in a current online issue of the journal Freshwater Biology where they describe experiments that examined some effects of fisheries management practices now in use in California mountain lakes where fish do not naturally occur. The research has value...

Brown Trout, Salmo trutta
2013-10-15 12:46:40

The Brown Trout (Salmo trutta) is originally a European species of salmonid fish. It includes both purely freshwater populations, referred to Salmo trutta morpha fario and S. trutta morpha lacustris, and anadromous forms referred to as the sea trout, S. trutta morpha trutta. The latter migrates to the oceans for the majority of its life and returns to freshwater only to spawn. The specific handle trutta comes from the Latin trutta, meaning, literally, “trout”. The lacustrine morph of...

The Golden Trout (Oncorhynchus mykiss aguabonita) is a subspecies of the Rainbow Trout (Oncorhynchus mykiss). It is also known by the name California Golden Trout and is native to Golden Trout Creek, Volcano Creek and the South Fork Kern River in California. It is most likely found at elevations 10,000 feet above sea level. This subspecies is also commonly placed with other subspecies of rainbow trout known as redband trout. The Golden Trout has flanks with a red, horizontal band along the...

Australian salmon are medium-sized perciform marine fish of the small family Arripidae. Four species are recognized, all within the genus Arripis; they are found in the waters off southern Australia (including Tasmania) and New Zealand. Despite the common name, Australian salmon are not related to the salmon (family Salmonidae) of the Northern Hemisphere; the former were named so by early European settlers after their superficial resemblance to the salmoniform fishes. Relatively long-lived...
