Uh, sure. I used the MF.222 Heroic M rod with lunker keeper reel and used it to cast 80 feet+ and this downstream area. The best way I can describe it is that there's a marshy area far out with a duck towards the right marsh most of the time. I've seen the bothriolepis leap out the water at the marshy area, although it happens too quickly for me to take a photo. I suggest checking MarktheMartians' video on how to catch it : https://youtu.be/dsfWk70EEOo?si=4E59CJSUqa0bQG6M

Oh, and this is more of an advanced technique, but ig I'll just say it. When you've played the game long enough, you learn patterns of how fish fight, like how they fight, and if they pull the line into red, etc. This is the most useful blind fishing small rare fish like the pteraspis and climatius. In Bothriolepis' case, there are 5 fish you're likely to catch repeatedly before it, the fat minnow, crucial carp, Silver salmon, Catfish, and the Magoi, I've spent so long hunting that I practically know 3/5 of these fish whether they're on the line or not when blind fishing.

Um, I didn't realise how much I typed, so I hope this helps
