I'm a bit doubtful about the age thing... I mean, how long do they keep them in the hatchery for? Its surely not growing in the lake there by any significant amount. My understanding, is that in fish-farming, fish can grow extremely fast. I have an uncle who is a chicken farmer in Canada, he was telling me about the economies of various protein production, and said this:
" For beef, you get approximately 1 pound of meat for every 10 pounds of feed. For pork, that number is about 4 to 1, chicken, is again, more efficient at about 2 to 1, but FISH... Fish farmers yield almost a whole pound of meat for every pound of feed"
My hunch is that the fish are just extremely overfed to become these big hog planters, and that once in the water, they will actually start to lose weight, rather than gain.
Not that a pellet-fed pig that's 18 months old is going to taste better than a wild fish of 6 years old because it is younger...
Now, onto your questions... Different species tasting better/worse. It is my opinion that the taste of the fish withing the Trout/Salmon family is almost entirely related to 2 things: Temperature of the water, and Diet.
FWIW - Brookies are less related to Salmon, as they are a Char, and evolutionarily further separated from Pacific Salmon than Rianbow/Cutthroat are, and further separated from Atlantic Salmon than Browns are. Though Mike, I also have heard the "Brook trout are closer to salmon" rationale... and while it might make sense, its just not true from a biology standpoint.
I keep fish occasionally when backpacking. I only ate 1 this last year, and will likely not bother next year (why waste time cutting fish up when I could be fishing!?!?!), but I have no qualms keeping a fish or 2 where the fishery can support some harvest and the laws are being observed. I have experienced varying meat color and taste between 2 backcountry sierra lakes, just hundreds of yards apart. Same fish (goldens), same elevation, water temp, etc... the only difference can be the food source, and the once lake with the dark salmon-colored flesh and more rubust taste, is known for having an abundant scud population.
This brings me to my beef with the pay-to-play lakes (for the record, I am eternally grateful that these places exist to lure "fishermen" away from our precious wild fisheries.):
You're not allowed to release fish. Now I've never fished there, and I probably never will, as it doesn't really tickle my fancy (Not a beautiful surrounding, not wild fish, and Expensive)... but seriously, why would a fisherman want to go there and only catch 5 fish, then go home. Oh well, we're not the target audience.
Fishing is the most wonderful thing I do in my life, barring some equally delightful unmentionables.
