On the right- no scales? Then my guess is it's a flounder. The sole looks tasty. I grew up on the North Shore, and caught some pretty good bottomfish as a boy at Ambleside and John Lawson parks. Ambleside had more sand near the drive-in entrance, so that's where most of the sole were. Just used garden or sea worms (Neres). The flounder would be from the Cap estuary- good sand worms there- as well as John Lawson. Rock and kelp greenling were the tastiest of them all. I even caught sea-run cutthroat and a coho while using worms! Got the coho in, but the cutthroat straightened the fine wire hook in the current Lots of Portugese guys would cast their smelt nets during the season as well. Any way you looked at it, it was a beautiful way to spend time as a youth on the seashore.
When I return to visit West Van once in a while, I drop by if I can for a walk. Some of the places close to these areas seem to be fished a lot from shore, by both fin and crab fishermen. Saw some true pole fishermen (Asian) last time, and learned some cute tricks just watching them. Anyone go there recently to fish? This walk down memory lane's got me winsome.
