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....

Every year, large amounts of hatchery-raised young salmonids are released into Swedish rivers and streams to compensate for losses in natural production. But these fish generally survive poorly in the wild.. Researchers at the University of Gothenburg have discovered why: the young fish get too crowded at the hatchery. The Swedish Research Council Formas is now granting $2.7 million USD (20 million SEK) to a Swedish/Nordic research project. The goal is to find out how the hatcheries can be...

JUNEAU, Alaska, Dec. 21 /PRNewswire/ -- Today is the shortest day of the year. During the dark winter months, sunlight can be an insufficient source of vitamin D which is vital for the absorption of calcium and phosphorous. Low vitamin D levels have recently been linked to a greater chance of developing diseases including diabetes and heart disease, several cancers and the common cold. The good news is that there is a delicious and healthy, vitamin D rich food source, that's also one of...

Exposure to common pesticides may hinder the growth and survival of ESA-listed salmon Biologists determined that short-term, seasonal exposure to pesticides in rivers and basins may limit the growth and size of wild salmon populations. In addition to the widespread deterioration of salmon habitats, these findings suggest that exposure to commonly used pesticides may further inhibit the recovery of threatened or endangered populations. "Major efforts are currently underway to restore Pacific...

Temperature differences, slow water could delay ocean entry Temperature differences and slow-moving water at the confluence of the Clearwater and Snake rivers in Idaho might delay the migration of threatened juvenile salmon and allow them to grow larger before reaching the Pacific Ocean. A team of Northwest researchers are examining the unusual life cycle of the Clearwater's fall Chinook salmon to find out why some of them spend extra time in the cool Clearwater before braving the warm Snake....

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...

A sonar station that counts salmon traveling up the Yukon River in Alaska malfunctioned this year, resulting in a smaller allowed catch, officials say. Russ Holder, federal fisheries manager for the Yukon, said the king salmon season looked like one of the poorest we've ever had, the Anchorage Daily News reported. In hindsight, it doesn't look as poor as those numbers indicated to us, he said. Because of the lower catch, enough fish got as far as the Canadian section of the river to fulfill a...

A number of Alaskan rivers have been closed to king salmon fishing after considerable numbers of the fish failed to return to spawn. The king salmon is a favorite meal for many Alaskans, but the fish's low population has left many Yukon River smokehouses without their signature dish. "It is going to be a tough winter, no two ways about it," said Leslie Hunter, a 67-year-old store owner and commercial fisherman from Marshall, Alaska. State and federal biologists are studying the problem. ...

The salmon population in the Gulf of Alaska has been dwindling as Pacific Ocean currents shift, Alaskan fisheries biologists say. The Anchorage Daily News said Saturday the Pacific decadal oscillation may be to blame for an increase in cooler waters in the Gulf of Alaska, where king salmon fishermen have struggled for two straight years. Changing water temperatures have also been blamed for the poor king salmon catches at Canada's Kodiak Island, Susitna Valley and Kenai Peninsula. As an...

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...

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...
