YES. Very interested.
I often accompanied my dad to the lake or pond during the evenings and weekends to go fishing when I was growing up. Catching them is really fun, especially when you use different methods to catch different types of fish. Catching them is great, but watching them is equally as enjoyable, IMO. This is why I've always wanted to take a dive inside a submarine or go scuba diving. Just today I stood for probably about half an hour on a bridge at the park, engrossed in watching the fish, lol.
I even have a couple Ichthyology books sitting on my bookshelf. Both well used. :) Fish are awesome!
