Uncommon Knowledge, Part 3

Part 2 of this post presented some info on body temperature, the language of motion, migration and spawning. Part 3 discusses species origins and diversity, claims to fame, and some points on diet.

Species Origins, and Man as Proliferation Mule

Rainbow and brown trout may be in the same family (Salmonidae), but they’re different species in different genera. Ancestrally, the family divided into two groups between fifteen and twenty million years ago. Oncorhynchus (from which rainbows spring) became isolated in the North Pacific, and Salmo (the browns faction) in the North Atlantic.

So the natural range of brown trout extends from Iceland to the Atlas mountains in North Africa and from Ireland to the Ural Mountains and the Caspian sea. Non-natives to North America, browns were introduced in the second half of the 19th Century from Germany and the UK. And there are no native brown trout of any kind in the southern hemisphere–all introduced by man. Conversely, rainbows are not native to Europe or the British Isles; they were introduced by man around the same time browns came to North America. more…

Uncommon Knowledge, Part 1

We may think we know our quarry. But I’ve spent part of this past winter doing some research, which has uncovered some knowledge tidbits of which I was unaware and which in many cases lend me an improved understanding. Some of them will result in trying things differently. I thought I’d share some of these facts with you, on the chance you might get a similar benefit.

So many aspects of trout lore are widely known by fly fishermen; but I’ve tried to avoid including the more commonly obvious items in this article. Instead I’m listing only items that could raise an eyebrow here and there. Also, I’ve uncovered one piece of info for one trout species, and another for another; so it’s very much a swiss-cheese-esque picture I can paint. Anyway, here we go: more…

Mitta Mitta – Too Late for Blackberry Pie

Guest Blogger: Mike Cline, Bozeman MT

The Murray River is Australia’s longest—some 1500 miles. The Mitta Mitta, flowing out of the Great Dividing Ranges in Victoria is the Murray’s largest headwater tributary. Hydro schemes, gold mining, dairy farming and logging has long transformed the Mitta Mitta valley into what it is today. Although Australian anglers are quick to praise the introduction of brown and rainbow trout into the Victorian mountains in the 19th century, they are also quick to show complete disgust for the introduction of the European Blackberry, Rubus fruticosus. Blackberries were introduced into the Sydney region in New South Wales in 1830 by early settlers. However, in a fateful decision that continues to plague trout anglers well into the 21st century, in 1851 the Government Botanist in Victoria, Baron von Mueller, and the first Curator of the Gardens at Melbourne University, Alexander Elliot recommended blackberries be planted along stream banks to prevent erosion. It didn’t take long for everyone to realize how bad a decision that was.
