Are you sure they take eggs from steelhead that return to the hatchery? Don't the hatchery guys fish the canyon(on the Wack) for brood stock..wild fish...i've had hatchery guys ask if the fish I've hooked was wild or hatchery and they even took a wild doe that i had landed and put it in a black plastic tube type cage and placed it back in the river to get picked up by the hatchery tanker truck later...but that was several years ago...maybe things have changed
I to have witnessed them with those black tubes every year i have been out there. they arent out all the time but you do see them and yes all the guys i have spoken to are always targetting the wild stock
why is this ? why do they seem to be after wild ones only?

Hatchery fish are not used for brood stock. The gene pool is kept as broad as possible by not reusing the same gene bank.
Having broodstocked in squamish the routine goes like this. First you catch the steelhead and carefully place in a tube and anchor it in a safe and well ventilated area,call hatchery guys and they pick it up and place in a live pool on the back of a truck and take to the hatchery, where they are kept until ready to spawn.Once fish have been spawned they are returned to the river as safely as possible so they can return again.Only wild fish are used for brood stacking.Although there is a ongoing debate about hatchery genetics opposed to wild,a recent twenty year study in the north has proven that there is no differance in genetics between wild stock and hatchery stock ......................................................
..........once upon a time the world was flat too! It's good to be picky though when it comed to broodstocking given the recent state of our west coast steelhead fishery!

There is no measurable difference between the genetics of hatchery and wild, precisley because there is no use of hatchery identified fish as brood stock. If 5% of a run is captured for brood stock and if only hatchery identified stocks were used as brood stock, over a very short time the gene pool would be reduced to only 5-10% of the original run. By ensuring that the brood stock are "wild" the diversity of the stock is ensured. Hatchery fish that survive the angler to actually spawn contribute their genetic code as well, meaning that "wild" fish have the real possibility of having one or both parents be hatchery fish. Although it took a 20 year study to prove it, it should come as no surprise that there is no difference in genetics in the two types of fish. The use of wild fish for brood stock every spawn was designed to produce exactly this result. Nice to see DFO get it right occasionallyhotrod said:
