(Chuckling) I hear you, Meadowlark. Who wants to work at having fun? Before I would be completely convinced about the results, though, I would want random samples of fish, rather than angling samples by themselves. Once yearly is enough for me, if seining. Heck, I might even figure out a way to sneak off and seine with you, if it's practical. Angling for samples is a bias toward most aggressive fish. While angling is valuable, it's only valuable in combination with random sampling. And, it wouldn't be too tough to track your feeding. If you have an automatic feeder, you can track how often the feeders are filled. If by hand, you can keep field notes. I really think this is important. If you feed 10 bags of feed through a year, and your fish grow to half pound each, you have data to deduce impact of feeding. If you aren't going to feed, records are even easier.
Your thesis is clear, and your methods are, too.
