Trout Eat More Mammals Than You’d Think
« on: March 31, 2015, 09:58:20 AM »
interesting article....


Trout Eat More Mammals Than You’d Think

University of Washington researchers recently published a study in Ecology of Freshwater Fish that concludes grayling and trout consume more mammals, namely shrews, than previously assumed. The findings address questions about the fishes’ feeding habits, which have long fueled intrigue among anglers and scientists. 

Of the 1,568 grayling and 2,424 trout examined over the 13-year study in Alaska’s Bristol Bay watershed, researchers found 75 shrews and one vole in the fishes’ stomachs. More interestingly, scientists discovered shrews in 25 percent of the fish larger than 12 inches in length.

In addition, the number of shrews found in the fish fluctuated during the course of the study, with eight years producing no shrews. Researchers surmise this variability may stem from changes in shrew’s abundance, not the fishes’ appetites.   

What remains unclear is how or why shrews enter the water in the first place.

Wow.
Learn something new all the time. A quick search resulted in this cool pic:

Thats something I've always wanted to try for bait when it comes to summer run steelhead and dolly varden. I can just imagine a big 2 to 10 pound trout is not going to pass up a tiny mouse swimming across a calm deep hole during summer.

They make a mouse imitation fly. They can really work well for lunker browns & bows.

The picture with all the shrews that were taken out of the trout is from the Kanektok River in western Alaska. This is the river that my brothers and I have several fly fishing camps on and have guided on since 1981. The mouse pattern is a "go to" pattern all season long and it is the fly that we use more than any other. Here is a pic of one of the many mouse patterns that we use. We mainly fish for rainbows with the mouse but it is not uncommon to catch Dolly Varden, Arctic Char, Arctic Grayling, Silver, Pink, and Sockeye Salmon.

Never seen such a thing. I have in my early years caught a few trout on poppers but i never thought they would eat anything like that. The biggest thing I've ever taken out of a trout was a large bug.

When we were kids we used to go out to the grain bins and catch mice.  Tie them to a hook, and let them swim around.  Caught some monster pike and bass.  Never really tried it for trout, but it doesn't surprise me.  I once saw a giant trout take out a 12" swimming garter snake.

Floated the Green River in Utah last September.  Each night we would switch to mice at dusk for the last mile or so float back to camp.   Caught 2-3 big Browns per night just messing around.  Used mice to catch big Brookes in Labrador as well.

You swing them down and across like a steelhead swing, right?
I've got a few mouse patterns in my box but I've never used them.

The ones I have look a lot like this pattern.

We catch a lot of Silvers on the mouse pattern. Silvers are very aggressive and will take a lot of different surface patterns.

I'd be totally comfortable throwing my 10' 6wt. With big flies I cheat and overline 1 size with a 7wt line. It's a fast rod too, which helps.
I've got a few spools for the reel, all for different applications.

A spey rod would be a great tool to use also if you're into that sort of thing.

Yep the Wulff  triangle taper works great for throwing large flies. I use it on my 6, 8 and 10 weights. I like this line for my nymphing purposes too

http://royalwulff.com/products/triangle-taper-floating-fly-line/

Bass poppers work well for trout too. I caught brook trout ( 3 to 6 lbs) in N Quebec until I got sick of catching them on mouse patterns, By end of trip cut off my hook

I fish Rocky Ford, Rock, Dusty Wenas Lakes at night with poppers and mouse patterns. You might be surprised how well they ;)

Great pics ground hog  :tup:
Those AK rainbows have awesome coloration
