A best friend Ryan used to work at the Chelan Hatchery. I volunteered to help on a burbot study. As part of the study, we assisted the State biologist with a Burbot survey in Lake Chelan. I believe this is legal to fish this way for burbot but double check.
We took weighted PVC tubes which had leaders secured by pop rivets every 18". I think there were about 5 leaders per pipe section. We sank the baited hooks secured to the tubes and left them on a buoy. We returned the next day, pulled the gear and took measurements and weights on the fish. I honestly can't remember what we used for bait. We had bait stolen from all the rigs and caught 5 fish. I'd never even heard of Burbot before Ryan asked if I wanted to go out and help. This was in 2002. Hap
