I've had other fresh-fish experiences, but those didn't involve any kind of fish that we ever bought in grocery stores. We'd sometimes have freshly-caught kokanee from Okanagan Lake, the summers when we had the cabin there. Either my grandfather and/or dad would go out in the boat and catch a few, or my grandmother would fish from the pier.
I caught my own fish one time, in the North Saskatchewan River. I remember being shocked at catching anything, and when I yanked my line out of the water, the fish smacked my grandmother right in the face (mom's mother, so I feel no guilt about that). She wasn't happy, since she'd wanted a picture of me catching my own fish (I was about 5 or 6 at the time, and we were on a Labor Day weekend camping trip). I caught two that weekend. They weren't large, but they tasted pretty good.
Some friends of my grandparents used to go fishing on Pigeon Lake, and they'd bring us a whitefish or two sometimes. My grandmother had a wonderful way with fish, when it came to preparing them. I remember her getting upset with me when I didn't want to put lemon juice on mine. She wouldn't believe me when I told her that it was so good that it didn't need anything else on it.
