Waypoint TV which prides itself on bringing viewers “the best fishing shows” is available free on Roku.
While not a big outdoorsman myself, I have plenty of family and friends that enjoy the outdoors and fishing and the programs on this channel seem of top notch. I checked out the channel and it loads very quickly and has a very high quality stream.
More on the channel from the developer:
The highest quality (HQ) fishing, hunting and outdoor shows and short films in one location. Anywhere, anytime, on any device. Video streaming at up to 1080p allows cord cutters free access to premium outdoor content.
