Unfortunately, no. Unless you are into "ripping lips", bass boats, and seeing how far a large mouth bass' lower lip will twist under it's own weight while held out of the water an arm's length away!
There is a "sports" section you can search, then it narrows to fishing ... let me know if you find anything good.
OK, I take that back ... there some good looking titles but they are all on DVD and not available for streaming. I've never seen "Fly Fish TV" but there is a series of those...
