When you exit your cave, walk directly to the left to the river. It's mainly at this location that you can spear catch the Black Bass, (I'm not sure if the fishing rod works as well.) When cooked, the Black Bass can fill you 30-34%. This is very helpful when you're low on food and stamina.
Also, take your fishing rod to the bottom of that particular river to where the rocks block where it empties out into the ocean. At this location, you can catch Salmon which is the only fish I know of that when made into jerky becomes Smoked Fish 1.
I'm not sure how much Smoked Fish 1 or Salmon fills you, but it's a way to get it into your scrapbook.
