Flexible Guts Used By Some Alaskan Trout For The Ultimate Binge Diet

University of Washington Imagine having a daylong Thanksgiving feast every day for a month, then, only pauper's rations the rest of the year. University of Washington researchers have discovered Dolly Varden, a kind of trout, eating just that way in Alaska's Chignik Lake watershed. Organs such as the stomach and intestines in the Dolly Varden doubled to quadrupled in size when eggs from spawning sockeye salmon became available each August, the researchers found. They were like...

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,...

Fast-growing farm-raised salmon and trout that are sterile can now be produced using a method developed by Agricultural Research Service (ARS) scientists. Blocking reproduction can enhance growth, and is important for fish being reared in situations where reproduction is undesirable. The method allows researchers to more efficiently and reliably produce fish that have three sets of chromosomes, instead of the usual two sets. Fish with the extra set of chromosomes can't reproduce, so the...

Forestry access roads can have undesirable outcomes on fish populations living in remote lakes due to increased access, reveals research written by Len Hunt and Nigel Lester of the Ontario Ministry of Natural Resources, recently published in the journal North American Journal of Fisheries Management. The presence, location, and extent of forestry roads have important effects on access point development on remote lakes in northern Ontario. Due to the popularity of walleye in northern Ontario,...

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...

By JOHN HOLYOKE When October rolls around, many Maine outdoors enthusiasts forget all about lakes, ponds and streams and start foraging for shotgun shells and orange caps. Make no mistake, ruffed grouse hunters are out and about - their season started Wednesday - but that doesn't mean there's not a pile of aquatic options available. In fact, many diehard anglers will tell you (as long as you agree not to let anyone else in on the secret) that come October, they enjoy some of the best...

GATLINBURG, Tenn. - Curious bears fattening up for winter craftily took part in a project to reintroduce native Southern Appalachian brook trout into streams in the Great Smoky Mountains National Park. Despite the interference, biologists completed the first phase of the planned reintroduction of the brook trout into several streams in the Tremont area of the park. From Sept. 7 to 19, the park closed an 8-mile segment of streams to poison nonnative fish. But bears tore into the baskets of...

By KEVIN MILLER; OF THE NEWS STAFF WINTERPORT - Part of a small but ecologically important tributary of the Penobscot River is getting a face-lift this week, and the results should benefit both the stream's aquatic inhabitants and residents of Winterport. Each spring and after heavy rains throughout the year, the tiny and meandering stream known as Cove Brook overwhelms a culvert that runs beneath Meadow Road in Winterport. Occasionally, the waters actually push the culvert downstream,...

2009-02-16 20:21:04

The Lake Trout (Salvelinus namaycush) is a species of freshwater char that is found mainly in lakes of Canada, Alaska, and the northern United States. They have been introduced into many other parts of the world including Europe, South America and some parts of Asia. In Canada, about 25% of the Lake Trout population is found in Ontario. However, only 1% of Ontario's lakes contain trout. The Lake Trout has been known to hybridize with Brook Trout, but such hybrids are almost always...
