Trout growth per year

I've been to Cabela's recently and they didn't have any tiger trout that I recall. I'm pretty sure they'd stick out to me if they were in there. I love looking at tigers.

The fish that sticks out most to me is the monster hook-jawed, hunchbacked brookie in there. He's a crazy looking fish. Some of their bass are swimming around funny because their backs have humped up so much.

As far as the food supply goes, I'd say that all depends on the actual types of food they're getting. Minnows, flies, pellets, worms? The fly eaters won't grow as quickly as the minnow eaters or the pellet fish. The pellet fish won't taste as good or look as pretty as a fish that eats natural foods IMO, but they probably grow way faster with a plentiful supply of nutritious power pellets getting tossed to them all day.

The fish at Cabela's kind of scare me, though. I love staring at them, but the big bows really look cloudy in their tank. Maybe it's just the light overhead, but it just doesn't look right to me.

Trout growth is highly dependent on environment. Biologists work hard to control factors that will keep fish growth at desired levels.

Read this paper on managing fish populations...it talks much about this subject:

"A Simple 4-step Method to Manage for Quality Fishing"

Here is a sample paragraph: "Fishermen often underestimate how fast trout can grow and overestimate the time it takes to grow a trophy trout. Large trout are most often a function of fast growth rather than old fish. Several good trout streams in southern Utah lack spawning habitat and are therefore stocked with fingerling brown trout. Brown trout of known ages commonly reach sizes of 18-20 inches in 3-4 years. We have measured brook trout from Boulder Mountain lakes that reached 5 pounds after surviving only two winters (3 summers of growth). Brook trout stocked as 3-inch fingerlings and at a rate of 50 per acre grow to a size of about 13 inches and 1.0 pounds in a year. If the stocking rate is increased to 100 per acre, growth decreases to about 0.5 pounds in a year. If growth is rapid, then harvest of trout by fishermen is not a greath threat to quality fishing. In either Boulder Mountain lakes or brown trout streams, moderate annual harvest of 16-18 inch trout is replaced annually by younger fish quickly growing to this same size. Even if 80-90% of the 16-18 inch trout are harvested, they are replaced each year and there are still some fish left to potentially grow even larger."
