Resources for trout fishing

I am looking for some trout fishing resources which are specific to different trout subspecies. I wrote a blog post a couple of months ago Trout Fishing Tips For Beginners, but I don't personally find it comprehensive enough. Now, I am looking to expand this post by adding species-specific fishing tips e.g. tips for rainbow trout, tips for brook trout and so on. The goal is to make beginners aware of finer nuisances for each of these species.

Although I have some ideas in my mind, I am not sure how to structure the content. I don't want to repeat the tips or techniques which are common. So I am looking for some relevant resources to get some ideas. I would be really thankful to anyone who can guide me here.

Best, Victor
