When I was younger, I used to slaughter them fishing backwater beaver ponds. Tiny spinner, or a tiny spoon always did the trick.
When I was a sophomore in high school, in my science class, I teamed up with one of the prettiest little girls on earth for our semester project. Our project was to start, stock and maintain an aquarium. It was a huge undertaking, but one we both thoroughly enjoyed. It was real long, so we created a stream in it. We filled it with all local fish including many grass pickerel, or grass pike as we called them. It was an awesome project, and my favorite of all time. Even though I was a perfect gentleman, I especially liked taking care of the project during our study halls when Patty and I were alone in the classroom...
Anyway, they were prolific fish and kept our aquarium lively and interesting.
