Just to elaborate Double Underhooks' post a bit regarding retention of dolly varden and bull trout. When you're freshwater fishing, in Region 2 you are not allowed to keep any wild trout and char from streams. There are no hatchery raised dolly varden and bull trout therefore all of them are required to be released. You are however allowed to keep wild trout in lakes, please check the daily quotas. The online freshwater fishing regulations can be found on
this page.
When you are saltwater fishing:
South of a line due west from Cape Caution, wild trout and char: catch and release only. Hatchery trout: 2, none of which may be less than 30 cm (so you can't keep any dolly varden and bull trout in Southern BC, as again, there are no hatchery raised dolly varden and bull trout).
North of a line due west from Cape Caution, hatchery and wild trout: 2, only one of which may be greater than 50 cm. None may be less than 30 cm.
Note: Wild trout are those with an adipose fin. Hatchery trout are those with a healed scar in place of the adipose fin.
Other saltwater fishing regulations are listed on
this page.
Anyways, I've never tasted one so can't really offer any thoughts on that. I've never caught them in lakes so can't really comment on that either. I have however caught quite a few in streams and it is one of my favorite species to target. Most dolly varden, bull trout are not picky, any large spinnerrs, spoons and flash flies will do the trick. Many times you'll see them following your lures before engulfing it. The fight is not too spectacular, I find the fish in June in the Fraser are the fiestiest ones.
