Parasites that breed in fish farms kill so many juvenile wild salmon that they threaten the survival of fish populations in some rivers and streams, Canadian researchers are reporting.

Fishing report and conditions for Northern California's Smith River. The river is known for excellent salmon and steelhead fishing in the Winter. From the editors of Casting Pond.com. Help for your Fly Fishing Day Dreams.

What a fantastic getaway and angling experience on the Angola's Pristine Coastline! Very reasonably priced. Check out the story. Fish include kabeljou (salmon), leervis (garrick) , various shark species and many more.

Toxins that once only surfaced in big fish are making their way down the food chain, a sign that the Great Lakes are getting even more polluted, says a new report. Now, smaller sizes of salmon, trout and carp have been slapped with strict consumption warnings - and some with outright bans - in many areas of the Lakes and particularly Lake Ontario.

That's what the House Resources Committee wants to know. The committee is probing the vice president's role in water resource-management decisions that are believed to have killed tens of thousands of fish. The Washington Post reported Cheney inserted himself into the minutiae of agency decisions to benefit conservative business interests.

Salmon is the common name for several species of fish of the family Salmonidae. Several other fish in the family are called trout. Salmon live in both the Atlantic and Pacific Oceans, as well as the Great Lakes and other land locked lakes.Typically, salmon are anadromous: they are born in fresh water, migrate to the ocean, then return to fresh water to reproduce. Folklore has it that the fish return to the exact spot where they were born to spawn; research indicates that at least 90% of the fish that spawn in a particular stream were born there. In Alaska, the crossing-over to other streams allows salmon to populate new streams, such as those that emerge as a glacier retreats. The precise method salmon use to navigate has not been entirely established, though their keen sense of smell is involved. In all species of Pacific salmon, the mature individuals die within a few days or weeks of spawning, a trait known as semelparity. However, even in those species of salmon that may survive to spawn more than once (iteroparity), post-spawning mortality is quite high (perhaps as high as 40 to 50%.) Those species average about two or, perhaps, three spawning events per individual.Salmon has long been at the heart of the culture and livelihood of coastal dwellers. Most peoples of the Northern Pacific shore had a ceremony to honor the first return of the year. For many centuries, people caught salmon as they swam upriver to spawn. A famous spearfishing site on the Columbia River at Celilo Falls was inundated after great dams were built on the river. The Ainu, of northern Japan, taught dogs how to catch salmon as they returned to their breeding grounds en masse. Now, salmon are caught in bays and near shore. Drift net fisheries have been banned on the high seas except off Northumberland on the east coast of England.Salmon population levels are of concern in the Atlantic and in some parts of the Pacific but in northern British Columbia and Alaska stocks are still abundant. The Skeena River alone has millions of wild salmon returning which support commercial fisheries, aboriginal food fisheries, sports fisheries and the area's diverse wildlife on the coast and around communities hundreds of miles inland in the watershed. The Columbia River salmon population is now less than 3% of what it was when Lewis and Clark arrived at the river.Both Atlantic and Pacific Salmon are important to recreational fishing around the world.In the southern hemisphere, there is a fish commonly called the Australian salmon but which is a salt water species and not related to the salmonidae. It is found along the southern coastline of Australia and Tasmania. Commonly caught with large beach nets, its use as a commercial fish has been declining over the last 20 years.
